Ram took equal masses of cooking oil and water repecitvely in two differernt identical beakers and placed them on identical heat engines and supplied same amount of heat to them .with the help o fthermometer he noted their temperautes which one of them would be hotter why?

The oil becomes hotter than water because the specific heat capacity of oil is less compared to that of water (1 cal `g^(-1)""^(@)C^(-1)`). The quantity of heat required to raise the temperature of 1 g of a substance by `1^@C` is called specific heat of the substance. Low specific heat means, for the same amount of heat supplied, the change in temperature is more.

Two different liquids of same mass are kept in two identical vessels, which are placed in a freezer that extracts heat from them at the same rate causing each liquid to transform into a solid. The schematic figure below shows the temperature T vs time t plot for the two materials. We denote the specific heat in the liquid status to be C_(L1) and C_(L2) for materials 1 and 2 respectively, and latent heats of fusion U_(1) and U_(2) respectively. Choose the correct option.
