Temperature’s effects on solids, liquids, gases Flashcards
1
Q
What happens when heat is increased?
A
When heat energy/temperature is increased, the particles in a substance increase in kinetic energy, and move further apart (density is decreased because the volume increases but the mass stays the same)
2
Q
What happens when heat is decreased?
A
When heat energy is decreased, the particles in a substance decrease in kinetic energy, and move closer together (density is increased because the volume decreases, but the mass stays the same)
3
Q
How do you change the state?
A
By raising or lowering the temperature enough, you can cause a change of state. Heating a solid will turn it into a liquid, and heating a liquid will turn it into a gas.
