WebSep 12, 2024 · The cumulative effect of all collisions is a net flux of heat from the hotter body to the colder body. Thus, the rate of heat transfer increases with increasing temperature difference Δ T = T h − T c. If the temperatures are the same, the net heat transfer rate is zero. WebMar 29, 2024 · To calculate latent heat, you need to multiply two numbers: Specific latent heat, the energy absorbed or released during a phase …
