thermal physics



solid :  it can be heated and converted into liquid .

it has a fixed volume and keeps its shape when a liquid is coooled it is converted into solid it cannot flow and its incompressable.

liquid: it can flow easily .its particles slide past each other

it can change  its shape depending on their container but the volume remains the same .

gas:  these molecules can spread out easily .when liquid is heated it turns into gas
