Temperature Change and Phase Change - Specific Heat and Latent Heat - From COLD ICE to Warm Water The quantitative relationship between heat transfer and temperature change is Q = mcAT, where Q is heat transfer, m is the mass of the substance, and AT is the change in temperature. The symbol c stands for specific heat which depends on the material and phase (for exmample, water and ice have different specific heat). The specific heat...
