Steepness of Heating Curve?

Postby Odalys Ugalde 1L » Sun Jan 31, 2016 11:20 pm

This is a general question regarding the heating curve as I was wondering how to accurately draw the steepness at each level, and whether this would depend more on time or temperature?

Thanks!

The steeper the slope of a heating curve, the lower the heat capacity. It is simply dependent on the value of the heat capacity which is defined as the amount of heat needed to raise the system's temperature by one degree.

A heat curve is temperature vs. heat added (x axis), so the slope of the curve is related to the substance's specific heat capacity. The more heat required to raise the substance 1 degree Celsius, the less steep the slope. Therefore it depends more on temperature since time is not part of the graph. Hope this helps!

It depends on joules and temperature because they are the x and Y axis of the graph, so if the the specific heat of a substance requires a lesser amount of joules to raise its temperature by a degree then it will have a steeper incline.

The above discussions are correct! Well done folks! It is simply that the steeper the slope, the less heat capacity. The explanation for it can be found in above discussion.
