WebWater’s heat of vaporization is around 540 cal/g at 100 °C, water's boiling point. Note that some molecules of water – ones that happen to have high kinetic energy – will escape from the surface of the water even at lower temperatures. WebNov 8, 2024 · We therefore introduce the specific heat capacity, c, which differs from one substance to the next, and which completes the relationship between heat transferred and temperature change: (5.3.3) Q = m c Δ T. The mass is always a positive quantity, and we define the specific heat capacity as a positive value, which means that Q > 0 when Δ T > 0. WebHeat exchangers are typically classified according to flow arrangement and type of construction. The simplest heat exchanger is one for which the hot and cold fluids move in the same or opposite directions in a concentric tube (or double-pipe) construction.
