Question : 15

Total: 43

Two liquids X and Y having the same mass are supplied with the same quantity of heat. If the temperature rise in X is twice that of Y, the ratio of specific heat capacity of X to that of Y is

2:1
1:2
4:1
1:4

Solution:

MC $x_{\theta}$ = MC $y_{\theta}$

$x_{\theta}$ = 2 $\times y_{\theta}$

MC(2 $y_{\theta}$ ) = MC $y_{\theta}$

⇒ 2C = C

=1 : 2
