Grade 12Thermal Physicsques:- The latent heat of vaporization of water is 2240 J. If the work done in the process of vaporization of 1 gm is 168 J, then increase in internal energy is? somil garg 15 Years agoGrade 12
Pramod J AskiitiansExpert-IIT-B15 Years agoDear student, following first law of thermodynamics dQ = dU + dW for 1 gm Lv = 224 J delU = delQ - delW = 224 - 168 = 56J i hope it explains !! :)
Anonymous7 Years agoGivenLatent heat of vapourisation=+2240J Work done=168JUsing 1st Law of thermodynamics:-2240=dU+168dU=2072 J
