The specific heat capacity of a pure substance can be found by dividing the heat needed to change the temperature of a sample of the substance by the mass of the sample and by the change in temperature. The heat capacity of a certain substance has been measured to be 2.65gCJ. Suppose 316.g of the substance are heated until the temperature of the sample has changed by 34.9C. Write an equation that will let you calculate the heat Q that was needed for this temperature change, Your equation shnuld contain only symbols. Be sure you define each symbol
