How does heat flow

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 ...
