Heat and Thermodynamics 1 Question 1
1. When gram of ice at (specific heat ) is added to gram of water at , finally no ice is left and the water is at . The value of latent heat of ice, in cal is
(a)
(b)
(c)
(d)
Show Answer
Solution:
- Key Idea In such kind of heat transfer problems, Heat given by water
Heat gained by ice and (heat) mass specific heat (Heat) mass latent heat temperature
- (mass
specific heat temperature)
Heat given by water is (specific heat of water is
Heat taken by ice is
Comparing Eqs. (i) and (ii), we get
