A hot liquid contained in a container of negligible heat capacity loses temperature at rate 3K/min 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 x/90K−1. Find x. (given that the rate of losing heat is constant).

The heat gain or heat loss for a change of temperature of ΔT of the substance is given as Q=mcΔT. Here, m is the mass of the substance and c is... View Article
