Question
The latent heat of vaporization of water is 2240J. If the work done in the process of vaporization of 1g is 168 J then increase in internal energy is
Options
A.1940J
B.2072J
C.2240J
D.2408J
Solution
We know that for first law of thermodynamics, equation is
Q = ᐃE + ᐃW
Here, Q = 2240; ᐃE = ? ᐃW = 168
ᐃE = Q - ᐃW = 2240 - 168 = 2072 J
Q = ᐃE + ᐃW
Here, Q = 2240; ᐃE = ? ᐃW = 168
ᐃE = Q - ᐃW = 2240 - 168 = 2072 J
