please list all the formulas for calculating the specific heat of a substance please.
thanks

specific heat = (heat added)/[(mass)(delta T)]

That is the equation that defines specific heat. It should be the only equation you need.
"delta T" is the increase in temperature.

For gases, a distinction is made between the heat capacity value at constant pressure (Cp) and the value at constant volume (Cv).
Cv - Cp = R,
where R is the gas constant per mass.
