TMHS Year 7 Science

Solids, Liquids and Gases.

You have been investigating the properties of Solids, Liquids and Gases in your lessons this week, both with me and Mr. Hudson. We have discussed why Forensic Scientists need to know the difference between Solids, Liquids and Gases. We have completed a practical circus where you observed similarities and differences between Solids, Liquids and Gases, and you will also look at the particle arrangement of Solids, Liquids and Gases.

But what actually are Solids, Liquids and Gases? How could we describe them? Why are they different to each other? Well, that’s your homelearning activity…..

I would like you to write a definition (a sentence to desribe the meaning) of what a solid is, a liquid is and a gas is. You could include examples, you should include descriptive words and you may want to research it before you write your comment. Click here for a good website to read.

Try and write it in your own words.

Remember to double check your writing before you submit your comment – happy blogging! Mr. Coles

    A solid is something hard and it will not break. e.g. table.
    A liquid is something like water. you can break the shape of a liquid.
    A gas is a like oxygen. it is lighter than a solid and a liquid.

    Solids: A solid is a hard objact that you can not squash or change shape e.g a brick. The solids particals stick together
    Liquids: A liquid is something that takes up the shape of a container it pours too e.g water. The liquids particals are spaced out a bit but not lots
    Gas: A gas can spread it also take the space e.g carbon dioxide. The gases particals are totally free.

    -A solid is a fixed shape and the particles cannot move from place to place. They cannot be compressed or squashed.
    -A liquid can flow easily and it takes the shape of its container, its particles have some space to move around
    -A gas can be compressed or squashed they also flow very easily and completely fill their container.

    Solids: Solids are when you cant brake the certain object and you cant compress the solid object there particles don’t have much space to move around in because they are held together with something called bonds!!

    Liquids: Liquids cant move around much but they can move around a little bit more than solids can they are also they cant be compressed or squished they take the shape of there container!!

    Gases: Gases have a lot more space to move around compared to solids and liquids. Gases don’t have any bonds that’s why they have free space to move around in. They flow and take the shape of a room also they can be compressed or squished!!

    Solids:Solids cannot be squshed and has a fixed volume
    liquids:Liquids also has a fixed volume
    Gases:do not have a fixed volume because it can get bigger and smaller

    Well the gasses can spread out easily unlike a solid the
    Particles can move freely. A solids particles can just shake. A liquids particles can move with the weak bond between the meaning they can move just a bit

    A solid is something that has a fixed shape. A liquid is something that you can pour and it does not have a fixed shape. A gas is something that does not have a fixed shape and goes in to any space it can.

    solid is lots of particals stuck together.
    gas is particals running free.
    liquid is particals together but it can flow unlike a solid.

    Carbon dioxide is gas which is in fire extinguisher. Gas is compressed in a small space but can still move but not much. It can not be squashed

    Liquid comes in different forms such as water, fizzy pop and cordial. Liquid is not compressed like gas it can move a round much more than gas.

    Solid is a object.The forms of solid are brick, wood, metal and steel. Solid is compressed and can not move in the slightest and can not be squashed.

    These are the examples of solid, liquid and gas

    Solids particles are close together by a strong force (bonds) and they can’t move from side to side.

    Liquids particles are close together, aranged in a random way and can move round each other.

    Gases particles are far apart and move freely around each other.


  • #   Ruby on 09.22.11 at 8:32 pm     Reply

    Solid-A solid has particles that are very close together. Like at a concert people get squashed very close and can barely move. The particles are held together by a strong force called bonds.

    Liquid-The particles in a liquid are sightly different to a solid as they are arranged in a random way. They also move around each other. Liquid cannot be compressed or squashed.

    Gas- A gas has much more free particles as they have more room to move about. Compared to solids and liquids, gas particles move much faster as they have much more room to move about in.

    Soloid. A solid is made up of tiny litle molecules which are so tightly compacted that it makes all chances of movement impossible (whithout being metal which you can melt down) liquid. The molecules in liquid are less compacted which makes them more free to move around the space that is given. Gas. The molecules in gas are the least bonded , which means that they will fill the space that they are given very easily.

    gas: A mostly invisible vapor which is released when open.

    Liquid: A fluid that takes the shape of it’s container.

    Solid: A solid is something that cannot be squashed.

    a solid is a rock hard block, grain ect…which cannot be bent or turned into a different shape.
    a liquid is a substance that is wet and can pour easy if boiled can turn into a gas.
    a gas is a substance that is everywhere such as air, some gases can be deadly but some are not ,right at this very moment we are breathing gas (air).

    A solid is an object you can touch and feel.

    A liquid is something that can pour and takes the shape of a cup anything like that.

    A gas is a clowd of chemical which often you can’t see, sometimes they could be deadly

    A solid means you cannot break it or it is very hard to break . Most solids are translucent i.e glass.
    A liquid means it can flow easily .Most liquids are transparent.
    There are gases in the air e.g nitrogen , carbon dioxide. Most gases are invisible i.e oxygen.

    Solid particles are tiny bits that are in an object that cannot move but vibrate.Frozen water is an example. Liquid particles are held by bonds as well but not as strong as solids which allows them to flow. Tap water is an example. unlike the other two gas particles have no bonds and move freely. Steam is an example.

    Well the soilds particles are clunched up together, thats why a solid it very very hard to squash. But water is different, because when you pour it out a jug it will spread, but not everywhere.But air is different as well eg: Get a fire extinguisher, let all of it out, and in seconds its spreaded everywhere. there all different

    Solids are a fixed shape. They can not move from place to place. They are held together by strong forces called bonds. Liquids are arranged in a random way. The particles are able to move around each other. Gas particles are far apart and can move quickly in any direction. There are no bonds between the particles.

    solid:a solid is a group of particles tightly squished together

    Liquid:a liquid is a group of particle that can move a little bit

    Gas:a gas is a group of particles that move freely


  • #   pierce on 09.25.11 at 7:29 pm     Reply

    The solids particals in a solid are all squashed up in lines.
    Liquids particals are squashed up but they can shuffle around.
    gasses are spaced out so they can move freely.


  • #   liam s on 09.27.11 at 5:42 pm     Reply

    solids particals are all together. luqids are near each other and a bit away. gases are miles a part


  • #   jordan on 09.27.11 at 7:32 pm     Reply

    solid :- a solid can’t be crushed

    liquid :- liquid is a runny fluid

    gas :- gas can be a flamable substance
    (e.g. gasoline)


  • #   tyler s on 10.05.11 at 3:09 pm     Reply

    solid particals are strongly bonded so they cant break.

    a liquid is very runny and the particles can breath more than the solids but less than the gas.

    the gas is free oxygen/air that moves about and has freedom unlike the other 2

    solid: a solid is where loads of particals are claped up together.
    liquid: a liquid is where loads of particals are slighty more apart.
    gasses: a gas is where loads of particals can move alover the place.

    solid – a solid is something that cannot be broken.
    liquid – a liquid is something that takes up the space of anything its poured into.
    gas – a gas is something like air.

    wow amazing


  • #   sofia.k on 10.25.13 at 5:06 pm     Reply

    solid- a solid is when the particles are stuck together like a chain and will not allow it self to be broken apart, it also cannot be compressed
    liquid- a liquid is when the particles are together but they move around slowly. the denser the particles the thicker the liquid, also water can be poured in and out of containers and take the shape of any container. it may also be separated, unlike a solid.
    gas- a gas is something we cannot see… well mostly, but some gases you can see. anyway a gas is when all the particles move around really fast and they are not together, because they are a wide distance apart from each other. also gases could be smelt but not all of them , some are flammable and some can kill.
