5) How is specific heat related to a change in temperature?
A
there is no relationship
B
the lower a substance's heat capacity, the more energy is required to raise that substances temperature
C
the greater a substance's heat capacity, the less energy is required to raise that substances temperature
D
the greater a substance's heat capacity, the more energy is required to raise that substances temperature
6) How does an object’s thermal energy depend on its mass?
A
the less mass, the more thermal energy
B
the more mass, the more thermal energy
7) How does the mass of an object affect the change in the temperature of an object?
A
There is no relationship.
B
Less mass = more change in temperature
C
Less mass = lower change in temperature
D
More mass = more change in temperature
