Understanding Phase Change: Effects of Heat on Kinetic Energy

AI Thread Summary
During a phase change, added heat primarily affects the kinetic energy of molecules, causing them to move faster. While some participants argue that potential energy also plays a role, the consensus leans towards kinetic energy as the main factor. The discussion emphasizes that only one answer is correct, with kinetic energy being the preferred choice. The conversation reflects differing opinions on the significance of potential energy in this context. Ultimately, the focus remains on the relationship between heat and kinetic energy during phase changes.

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:

Thread 'Voltmeter readings for this circuit with switches'

TL;DR Summary: I would like to know the voltmeter readings on the two resistors separately in the picture in the following cases , When one of the keys is closed When both of them are opened (Knowing that the battery has negligible internal resistance) My thoughts for the first case , one of them must be 12 volt while the other is 0 The second case we'll I think both voltmeter readings should be 12 volt since they are both parallel to the battery and they involve the key within what the...

Thread 'Trying to understand the logic behind adding vectors with an angle between them'

My initial calculation was to subtract V1 from V2 to show that from the perspective of the second aircraft the first one is -300km/h. So i checked with ChatGPT and it said I cant just subtract them because I have an angle between them. So I dont understand the reasoning of it. Like why should a velocity be dependent on an angle? I was thinking about how it would look like if the planes where parallel to each other, and then how it look like if one is turning away and I dont see it. Since...
