At normal temperature (0°C) and normal pressure (1.013 x 105 N/m2) when 1 gm. of water freezes, its volume increases by 0.091 cm3. What is the change in internal energy.
  • a)
    ΔU = — 366 Joule
  • b)
    ΔU = — 336 Joule 
  • c)
    ΔU = 400 Joule
  • d)
    ΔU = -400 Joule
Correct answer is option 'B'. Can you explain this answer?

Heat given by 1 gm water when it freezes into ice 
Q = mL= 1 gm x 80 cal / gm = 80 cal.
= 80 x 4.2 Joule = 336 Joule
The external work done against the atmosphere when its volume increases by 0.091 cm3

By the first law of thermodynamics, the change in internal energy

Here Q is taken negative because heat is given by the system.
Thus internal energy decreases by 336.0093 Joule.
