pretty much everything.....depends on the heat
Well, solids. For example, when you heat up metal is expands and when you freeze it, it contracts
it expands and contracts when the temperature drops, the mercury contracts...when the temperature increases, the mercury expands
The diaphragm expands and contracts automatically, forcing air into and out of the lungs.
the Mercury in a thermometer expands when heated and contracts when the temperature cools down.
Matter generally expands when heated and contracts when cooled. This is due to the changes in the kinetic energy of the particles within the matter. The expansion or contraction allows matter to adjust its volume to the space available.
It doesn't, it expands and contracts in the space it has.
Glass expands and contracts according to the ambient temperature.
expands and contracts to accomodate varying amount of materials
When rubber is heated it expands and when it cools it contracts.
adiabatic
When one muscle in a pair contracts the other expands.
A sealed bellows that expands and contracts depending on the ambient pressure.
