WebExperiments show that the heat transferred to or from a substance depends on three factors—the change in the substance’s temperature, the mass of the substance, and certain physical properties related to the phase of the substance. The equation for heat transfer Q is. Q = m c Δ T, 11.7. where m is the mass of the substance and Δ T is the ... WebScientists define heat as thermal energy transferred between two systems at different temperatures that come in contact. Heat is written with the symbol q or Q, and it has units of Joules ( \text J J ). Heat is transferred from the surroundings to the ice, causing the phase change from ice to water.
