The quantitative relationship between heat transfer and temperature change contains all three factors: Q = mcΔT, where Q is the symbol for heat transfer, m is the mass of the substance, and ΔT is the change in temperature. The symbol c stands for specific heat and depends on the material and phase.
HEAT TRANSFER AND TEMPERATURE CHANGE. The quantitative relationship between heat transfer and temperature change contains all three factors: \[Q=m c \Delta T, \nonumber \] where \(Q\) is the symbol for heat transfer, \(m\) is the mass of the substance, and \(\Delta T\) is the change in temperature.
28 Απρ 2023 · The heat capacity is a smooth, continuous function of temperature except for a small number of discontinuities. These occur at temperatures where the substance undergoes phase changes. These can be changes from one solid phase to another, melting to convert a solid phase to the liquid, or vaporization to convert the liquid to the gas.
