Room latent heat formula
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. WebStep 3/4. Step 4/4. Final answer. Transcribed image text: + 1) Suppose you wish to turn a room temperature glass of water into ice at −10∘C. The glass contains 200ml(200 g) of water and begins at 22∘C. The specific heat of water is 4186 J/kg⋅ ∘C and its latent heat of fusion is 334 kJ/kg. The specific heat of ice is 2090 J/kg⋅ ∘C.
