Use them to help you cross out the wrong information in the table below so you are left with only the correct information.
Extension: Using your table above, explain the following
a) Why does a solid have a fixed shape? A solid has a fixed shape because the particles are very close together and arranged in strong regular lines although they vibrate the particles are so packed together they can’t move.
b) Why can a gas be easily squashed? A gas can be easily squashed because the particles are very far apart and fast moving. This means that there’s a lot of free space between the particles so the gas can be easily compressed.
c) Why can a liquid be easily poured? A liquid can be easily poured because the particles are slightly further apart than in a solid. The particles are close but free to move past each other but they do all stick together. The particles can fill out the bottom of a container and move freely because of the particles that aren’t tightly packed together.
