Compléter Changes of stateVersion en ligne Introduction to the changes of state in english. Taken from https://www.youtube.com/watch?v=DE3LCPfP8N8 par Brittany Moore 1 Matter can be in states : form , form and form . Solid state is characterised by having a size and volume , although in some cases we can change its size , like with plasticine or clay . In these cases they are malleable solids . Liquid state is characterised by having a size and volume . Liquids take the container ? s shape , like this jug or glass . Gas state is characterised by having a variable size and . In the same way that liquids take the shape of the that ? s holding them , but gases always occupy the full volume in the container . Now we know about the three states of matter but ? Do you know how we can change from one state to another ? Changes in state happen after or matter , and there are different types : melting , solidification , evaporation and condensation . happens when matter changes from its solid form to liquid form , and happens after rising temperature . When we heat an ice cube , or we leave it at room temperature it melts and changes from solid to liquid . is the opposite of melting . Matter changes from liquid to solid form . It happens when we put water in the and it turns into ice . It goes from liquid to solid . is when matter changes from liquid to gas , after liquids are heated . For example when we water , it turns into water vapour . It turns from liquid into gas . is the step from gas to liquid , and it happens when matter in gas state is cooled .
