I have a question regarding the calculation of specific heat capacity for someone

2022-03-23View Original

Thread Content

The specific heat capacity of water changes with temperature. When calculating the heat required for temperature rise, which temperature’s temperature rise should be used as a reference? Should it be the product of the specific heat capacity at temperature t1 and mass, minus the product of the specific heat capacity at the initial temperature t0 and mass temperature? C1mt1-C0mt0

The specific heat capacity is directly a function of temperature, not of the temperature rise; the latter is used instead

Okay, I wrote it wrong; what I meant to write was “the specific heat capacity at which temperature””

If it is possible to derive the equations relating specific heat capacity to temperature within two temperature ranges, using integration methods would yield more accurate results

The accurate method is integral calculation, while a rough estimate is made using the average specific heat capacity
