Provided that the latent heat of steam is 540 cal/g, calculate the specific heat of the metal. Sol: Let c be the specific heat of the metal. Heat gained by the metal. Q = mcΔt. ⇒ Q = 60 x c x (100 - 20) ⇒ Q = 60 x c x 80 cal.

Heat Capacity and Latent Heat - Grade 11 Physics

WebSpecific latent heat is the amount of energy required to change the state of 1 kg of a substance without changing its temperature. The specific latent heat changes from substance to substance. It can be determined experimentally using the following formula L = E m specific latent heat = energy mass WebLatent heat is measured in units of J/kg. Both Lf and Lv depend on the substance, particularly on the strength of its molecular forces as noted earlier. Lf and Lv are collectively called latent heat coefficients. the sara series
