1
Internal energy is the total:
Answer & explanation
Correct: option C
Internal energy = kinetic + potential of all particles.
2
During boiling at constant pressure, temperature:
Answer & explanation
Correct: option B
T stays at the boiling point until all liquid has changed.
3
What does temperature measure?
Answer & explanation
Correct: option B
Temperature ∝ average kinetic energy.
4
When ice melts, energy added goes to:
Answer & explanation
Correct: option B
Bond energy (potential) rises; kinetic (T) stays constant.
5
Sloped sections of a heating curve indicate:
Answer & explanation
Correct: option B
Sloped = T rising; particles speeding up.
6
A glass of water at 20 °C and a swimming pool at 20 °C. Which has MORE total internal energy?
Answer & explanation
Correct: option B
Internal energy is total — more particles means more total energy, even at the same temperature.
