Heating Curve

Why is the heating slope for a liquid less steep if it has a higher heat capacity compared to a lower heat capacity that results in a steeper slope?

Re: Heating Curve

If something has a higher heat capacity that means it can absorb more energy before it increases in temperature. Therefore, it should have a smaller slope because the temperature is increasing at a lower rate due to the higher heat capacity of the liquid.

Re: Heating Curve

The heating curve would have a smaller slope because the substance's high heat capacity means that it would be able to absorb more energy for each increase of one degree in temperature.

Re: Heating Curve

Think of the heat capacity as the amount of heat something can absorb. The larger the value, the more heat it will be able to absorb before it transitions to the next phase. If it can absorb more heat,it will take longer for this process to happen and will thus have a less steep slope.

Re: Heating Curve

The slope corresponds with the coinciding heat capacity of that specific liquid. The higher the heat capacity, the more heat is require to raise its temperature so it will take longer for the temperature to rise thus leasing to a smaller slope and less steep curve.
