Two identical calorimeters A and B contain an equal quantity of water at 20 °C. A 5 g piece of metal X of specific heat 0.2 cal g -1 °C -1 is dropped into A and 5 g piece of metal Y is dropped into B. The equilibrium temperature in A is 22°C and that in B is 23°C. The initial temperature of both the metals was 40°C. The specific heat of metal Y (in cal g -1 °C -1 ) is
A
B
C
D
0.4
Text Solution
Verified by ExpertsThe correct answer is:
A
For X : 5 x 0.2 x (40 - 22)
= m x C x (22 - 20)
For Y : 5 x C x (40 - 23)
= m x C x (23 - 20)
