Heat and Thermal ExpansionHard
Question
When unit of water boils to become steam at 100oC, it absorbs Q amount of heat. The densities o water and steam at 100o C are ρ1 and ρ2 respectively and the atmospheric pressure is ρ0. The increase in internal energy of the water is : -
Options
A.Q
B.Q + P0 
C.Q + P0 
D.Q - P0
Solution
Q = ᐃU + W ⇒ +Q = ᐃU + P0 (V0 - V0)
⇒Q = ᐃU + P0 ᐃU = Q + P0
⇒Q = ᐃU + P0
ᐃU = Q + P0 Create a free account to view solution
