How is the specific heat capacity determined?

We were given the formula q = (g)(Csp)(delta T), so we can just rearrange the variables to get Csp = q / (g * delta T). We would need to know q (energy), the mass of the substance (g), and the change in temperature (delta T).

Specific heat capacity is determined by taking the heat capacity of the substance and dividing that by the amount of substance present in grams. This is an intensive property and will have the units of J/(degreeC*g). You can also get the specific heat capacity by using the formula q = (g)(Csp)(delta T).

The specific heat capacity is a constant intensive property for a given material. This is calculated using the formula above from the other answers, but in a experiment they are gathered through the use of a calorimeter.
