Which of the below statements are true? A. There can be a change in heat (kJ) without the temperature changing by. Heat remains constant through a change of state c. Temperature changes through a change of state d. Heat and temperature are the same

A. There can be a change in heat (kJ) without the temperature changing by.

Explanation:

A. There can be a change in heat (kJ) without the temperature changing by.

This is correct. It is what happens whenever there is a change in state.

B. Heat remains constant through a change of state

This is incorrect. During change of state like boiling, the amount of heat changes.

c. Temperature changes through a change of state

This is incorrect. During boiling, the temperature is fixed at 100 celcius

d. Heat and temperature are the same

This is incorrect. Heat refers to the total energy of the molecule. Temperature on the other hand is a measure of how hot or cold something is.  Plus they have different units.
