Heat Transfer Flashcards
1
Q
Describe the two different types of heat
A
- Sensible
a, The amount of heat an object contains related to its temperature - Latent
a. The amount of heat an object contains related to changes of state
b. Most energy
2
Q
Describe the two types of latent heat
A
- Latent heat of vaporization: Gas to liquid or vice versa
- Latent heat of fusion: Liquid to solid or vice versa
* Latent heat of vaporization has more energy
3
Q
What are the driving forces and resistance for conduction?
A
Driving force: temperature difference
Resistance: Insulation
4
Q
How can the rate of heat transfer be reduced?
A
- Decrease driving force
2. Increase resistance
5
Q
How can the resistance to heat transfer due to conduction be increased in a building?
A
- Add insulation or add higher quality insulation
2. Increase surface area
6
Q
How can the driving force for heat transfer be reduced in a building?
A
Set the inside temperature closer to the outside temperature
