Difference temperature and heat
WebNov 13, 2024 · As a body loses or gains heat, its temperature changes in direct proportion to the amount of thermal energy q transferred: (2.2.3) q = C Δ T. The proportionality constant C is known as the heat capacity. (2.2.4) C = q Δ T. If Δ T is expressed in kelvins (degrees) and q in joules, the units of C are J K –1.
