Topic:#7 Latent Heat, Thermal Properties of Matter

Duration: 14:08

Description:When sir is writing the expression for 'heat given by steam' why does he add the factor "mC(100-x)" to the latent heat.I mean it should be substracted as it is the heat which is being given out from the latent heat.

One more thing, when ever we find change we do "final-initial" but here sir wrote (100-x) in the expression of heat given by steam.I think it should be (x-100).

Please clarify my doubts.If I am wrong please tell me the correct explaination
