Dimensional Analysis for Molar Heat Capacity

Postby Bryce Ramirez 1J » Sat Jan 25, 2020 6:54 pm

When trying to cancel out the units for finding the heat needed to change an amount of moles of a substance, do you have to convert the temperature from Celcius to Kelvin? The units for the molar heat capacity have K in it, so I assumed the heat would have to be used in Kelvin, but I am not sure. Can someone explain how the units would cancel out?

If the units have K in it, then I would convert from Celsius to Kelvin so that it cancels out. The units need to be the same in order for it to cancel, so it would be easier to convert the temperature.

Can someone please define molar heat capacity?

By definition, the Molar Heat Capacity is the heat capacity divided by the amount (in moles) of the sample. When using it to determine the heat, you would just need to find the value given in table 4A.2.
