What is isolated system ?
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 $T$ versus time $t$ plot for the two materials. We denote the specific heat in the liquid states to be $C_{L 1}$ and $C_{L 2}$ for materials 1 and 2, respectively and latent heats of fusion $U_1$ and $U_2$, respectively. Choose the correct option.
If water at $0\,^oC$ kept in a container with an open mouth, is placed in a large evacuated chamber,
Triple point of water is
Match the following according to conversion by heat :
Column $-I$ | Column $-II$ |
$(a)$ Required heat to convert solid into gaseous. | $(i)$ Latent heat of fusion |
$(b)$ Required heat to convert solid into liquid. | $(ii)$ Latent heat of vaporization. |
