Slope of heating curve

Postby Artin Allahverdian 2H » Tue Feb 12, 2019 5:35 pm

Why does a higher heat capacity mean a less steep slope?

A higher heat capacity means a substance can better withstand and input of heat and will not increase its temperature as easily. Hence, a higher heat capacity means a less steep slope.

I think that in general, the high specifc heat would mean that it would be harder to change the temperature of that substance and so the slope would be not as steep as something that would be easier.

Higher heat capacity means a less steep slope because it requires more energy (along x-axis) to raise the temperature (along y-axis) of the substance. In terms of the heating curve graph: when looking at y/x, the larger x is, or the energy, the smaller the slope-> less steep.

It is a shallower slope because it is a slower process to reaching the next phase change whereas for low heat capacity, it takes less energy and heat and thus has a steep slope because it reaches the next phase easier.

the slope refers to the rate, so lower heat capacities = steeper slope because it can reach the next phase quicker and higher heat capacity, more shallow because more energy and time is needed to reach next phase change

If a substance has a lower heat capacity, that means it will take less energy (x) to make an increase in the temperature (y). This results in a steep slope. Conversely, if a substance has a higher heat capacity, it takes more energy (x) to increase the temperature so it will have a smaller slope.

Because the substance can withstand more heat the slope will be much less steep.

What is a heating curve and what does it represent?
