Questions
One gram of water of volume 1 c.c becomes 1671 c.c of steam when boiled at a pressure of one atmosphere. The latent heat of vaporization of water is 540 cal/gm. Find the increase in internal energy (1 at. pressure = 105 N/m2)
detailed solution
Correct option is B
ΔU=Q−WHere W=P×V2−V1=105×(1671−1)×10−8J=167Jand Q = 1x540cal∴ΔU=540−1674.2cal=500.24cal.Talk to our academic expert!
