Heat always travels from cool to warm
Did you know?
WebHot objects have heat energy. Heat energy always moves from something hot to something colder. There is no such thing as cold energy, so an object can only get colder by heat energy moving away from it. There are three ways that heat energy can move: Conduction. Convection. Radiation. Conduction 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 ...
