Specific heat is the heat required to raise the temperature of 1 g of a substance by 1 °C. Based on this definition, what is the equation to calculate specific heat? Select one: heat O specific heat = %3D (mass x temperature change) temperature change specific heat = mass (heat x tempetature change) specific heat = mass temperature change O specific heat = (mass x heat)
