Thermal Energy Flashcards
1
Q
State kinetic mode of matter?
A
Every matter is made of small particles that are constantly moving.
2
Q
State examples of things that sublimate.
A
- Iodine
- Dry ice (CO2)
- Diamond
- Aluminium chloride
- Ammonium chloride
3
Q
Explain and state an endothermic process.
A
Take in heat energy to occur
1. Melting
2. Boiling
3. Sublimating
4
Q
Explain and state an exothermic process
A
That releases heat energy to occur.
1. Freezing
2. Condensation
3. Deposition
5
Q
Why does evaporation cause cooling.
A
Evaporation causes a cooling on the surface of a liquid because the melon the surface gain energy from the sun’s radiation or from wind, start moving faster and eventually break free from the force keeping them in the liquid state and escape to go to the gas state leaving behind molecules with less kinetic energy.
