Want this question answered?
Thermal expansion will occur in just about all of the 15 or more phases of matter: whether it be solid, liquid, gas, etc.
it is used for bimetallic strip thermometers which is there in refrigerator and oven.
Analog thermometers are based on the fact that matter expands and contracts in response to changing temperature. This is able to show smooth variation because the expansion and contraction is distributed among trillions of molecules per cubic millimeter. Since the expansion or contraction of each molecule is ultimately miniscule, the accumulated effects are excessively smooth.
physical change
an explosion.
the matter always stays the same, expansion and contraction just means the matter is becoming more/less spread out from one another. A change in the state of matter is turning from solid-liquid-gas. The amount of matter always stays the same!

Thermometer is based on the expansion of matter as temperature increases.
Thermal Contraction
thermal expansion
The characteristic of matter that causes it to expand when the temperature increases and contract when the temperature decreases is known as thermal expansion. This is because as the temperature rises, the particles within the material gain kinetic energy and move more, causing the material to expand. Conversely, when the temperature decreases, the particles lose kinetic energy and move less, leading to contraction.
Not only is there not enough matter (dark or otherwise) to stop and reverse cosmic expansion, the rate of that expansion has been increasing over time. It would appear that dark energy is achieving "victory" over all matter.
Thermal expansion is the tendency of matter to change in volume in response to a change in temperature.
Yes. Dark energy is responsible for the expansion of the universe.
