6. What is the equation for specific heat capacity?
- Change in thermal energy = SHC x mass x temp chang
- SHC = temp change x kinetic energy
- SHC = 1/2 x mass x temp change
7. What is the equation for energy efficiency?
- input/not useful output
- useful output/ total input
- power x time
8. What is the equation for Gravitational potential energy?
- = height x kinetic energy
- = mass x gravity x height
- = mass x height
9. What is convection?
- Man's still not that hot
- The movement of energetic particles from hot to cold regions
- The movement of particles across a concentration gradient
- The movement of heat through a solid
10. What is the equation for Energy lost from gpe store?
- Energy lost from gpe store = Thermal energy lost
- Energy lost from gpe store = Energy gained in kinetic store
- Energy lost from gpe store = Energy gained overall
11. What does 'work done' mean?
- Energy transferred
- Potential difference in a circuit
- When particles collide
12. What is an energy efficient device?
- It transfers energy quickly
- It transfers most of the energy to the desired type of energy
- It works for a long time
13. What is conduction?
- The movement of heat from cold to hot
- The transfer of heat from hotter to colder regions
- The transfer of heat through particle collisions
- Man's not hot
14. What is the equation for power?
- = energy/mass x time
- = work done/time
- = time x energy
15. What is the equation for kinetic energy?
- Kinetic energy = 1/2 x mass x speed squared
- Kinetic energy = 1/3 speed x energy transferred
- Kinetic energy = 2 x mass x speed
16. Which of these is an energy store?
