Heat Capacity
Can someone explain why the slope of a heating curve is greater for samples with a low heat capacity, than for those with a high heat capacity?

Re: Heat Capacity
I think that a lower heat capacity means that it can reach a certain temperature without needing as much heat. Therefore something with a high heat capacity would need more heat to reach the same temperature, and that would take a longer time. That is my reasoning for why the slope of a heating curve is greater for samples with a low heat capacity. I could be wrong though.

Re: Heat Capacity
The reason that a greater slope equals a lower heat capacity is because if you think about it, a lower heat capacity means it can hold less heat comfortably. Therefore, any heat added would effect the substance more rapidly than one that had a higher capacity for it, causing it to have a higher rate/slope.

Re: Heat Capacity
The slope would be steeper for a lower heat capacity because the the same amount of energy input (x axis) would cause a greater increase in temperature (y axis), compared to something with a high heat capacity.

Re: Heat Capacity
A steeper slope would indicate a lower heat capacity since it heats up faster with less energy; conversely, a flatter slope would indicate a higher heat capacity because the same amount of heat is heating the substance in question slower.

Re: Heat Capacity
Liquids have a higher heat capacity than gases or solids so their slope is going to be less steep.
