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 be2.76j·g°c suppose 466.g of the substance are heated until the temperature of the sample has changed by 39.4°c. write an equation that will let you calculate the heatqthat was needed for this temperature change. your equation should contain only symbols. be sure you define each symbol.
