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

MC\(x_\theta\) = MC\(y_\theta\)
\(x_\theta\) = 2 \(\times y_\theta\)
MC(2\(y_\theta\)) = MC\(y_\theta\)
⇒ 2C = C
