Understanding Phase Change: Effects of Heat on Kinetic Energy

Click For Summary

Homework Help Overview

The discussion revolves around the effects of heat on kinetic energy during phase changes of substances. Participants are exploring the relationship between heat, temperature, kinetic energy, potential energy, and mass in this context.

Discussion Character

  • Conceptual clarification, Assumption checking

Approaches and Questions Raised

  • Participants are debating which effects of added heat are correct, with some suggesting that kinetic energy is the primary factor, while others believe potential energy should also be considered. There is uncertainty about whether only one answer can be correct.

Discussion Status

The discussion is active, with multiple interpretations being explored regarding the effects of heat on kinetic and potential energy. Some participants express confidence in their answers, while others question the exclusivity of the options presented.

Contextual Notes

There appears to be a focus on the correctness of specific answers in a multiple-choice format, which may influence the discussion dynamics. Participants are navigating assumptions about the relationship between heat and energy types.

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
 
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?
 
i guess b is correct ... but c should also be an answer
 
Thanks.
 
you're welcome :smile:
