Solution

The correct option is A Latent heat given away by the liquid
Phase changes are always isothermal because in that case the heat given or taken is not handled by specific heat but latent heat.

Statement (A):The constant temperature at which a solid change into liquid state by absorbing heat energy is called melting point.

Statement (B): The constant temperature at which a liquid changes into gaseous state by absorbing heat energy is called point.

Statement (C): The melting and boiling points of a pure substance is always a constant and is a good measure of finding the purity of the substance.

A hot liquid contained in a container of negligible heat capacity loses temperature at rate $3 K / m i n$ just before it begins to solidify. The temperature remains constant for $30$ min. If the ratio of specific heat capacity of liquid to specific latent heat of fusion is $\frac{x}{90} K^{- 1}$ . Find $x$ . (given that rate of losing heat is constant).
