Calculate the specific latent heat of vaporization of steam of 1.13 x 106J of heat energy is required to convert 15kg of steam to water.

Calculate the specific latent heat of vaporization of steam of 1.13 x 106J of heat energy is required to convert 15kg of steam to water.
A. 7.53 x 105 Jkg−1
B. 7.53 x 10-2Jkg−1
C. 7.53×104Jkg−1
D. 7.53 x 10-3Jkg−1

Correct Option: Answer is C

Quantity of heat = mass(m) × specific latent heat (L)
Q = mL
L = Q/m
= 〖1.13 x 10〗^6/15
= 7.53×104Jkg−1
