Room latent heat formula
WebSpecific latent heat is characterized as the measure of heat energy (heat, Q) that is consumed or discharged when a body experiences a steady temperature process. The formula for specific latent heat is: L = Q/m. … WebApr 4, 2024 · The formula for latent heat is given by, L = Q / M. L = 300 / 5. L = 60 k.cal/kg. Hence latent heat value is 60 k.cal/kg. 2. At 20°C, a piece of metal has a density of 60g. …
