WebNov 5, 2024 · Heat Transfer: (a) Heat transfer occurs spontaneously from a hot object to a cold one, consistent with the second law of thermodynamics. (b) A heat engine, represented here by a circle, uses part of the heat transfer to do work. The hot and cold objects are called the hot and cold reservoirs. WebDec 23, 2024 · The formula for specific heat looks like this: c = \frac {Q} {m \Delta T} c = mΔT Q Q Q is the amount of supplied or subtracted heat (in joules), m m is the mass of the sample, and \Delta T ΔT is the difference between the initial and final temperatures. Heat capacity is measured in J/ (kg·K). Typical values of specific heat
