Which statement accurately describes what happens when ice melts in terms of energy?
A. The ice releases energy which causes the water molecules to have less kinetic and potential energy, changing their configuration from solid to liquid.
B. The ice absorbs energy which causes chemical bonds to break, changing ice to water.
C. The ice releases energy which causes chemical bonds to break, changing the ice to water.
D. The ice absorbs energy which causes the water molecules to have more kinetic and potential energy, changing their configuration from a solid to a liquid.

In the first law of thermodynamics, ΔE=Q−W , what does ΔE stand for?
A. the heat added to the system
B. the internal energy of the system
C. the change in the internal energy of the system
D. the work done by the piston
In a heat engine, 500 J of heat enters the system, and the piston does 300 J of work.
What is the final internal (thermal) energy of the system if the initial energy is 1500 J?
A. 200 J
B. 800 J
C. 1300 J
D. 1700 J
The thermal energy of a system increases by 600 J, and 1400 J of heat is added to the system.
How much work did the system do?
A. 600 J
B. 800 J
C. 1400 J
