Understanding Phase Change: Effects of Heat on Kinetic Energy

[mopar969]

When a substance undergoes a phase change, the added heat changes (a) the temperature, (b) the kinetic energy, (c) the potential energy, (d) the mass of the substance.
I believe the answer is kinetic energy because the molecules move faster.

only 1 answer is correct?
coz i guess both b,c

 

[mopar969]

Only one answer is correct so I think the best answer is kinetic energy which is option B. What do you think, am I right?

 

[cupid.callin]

i guess b is correct ... but c should also be an answer
