The figure given below shows the cooling curve of pure wax material after heating. It cools from A to B and solidifies along BD . If L and C are respective values of latent heat and the specific heat of the liquid wax, the ratio L / C is

Cooling graphs are drawn for three liquids a,b and c The specific heat is maximum for liquid .

A given mass m of a solid is supplied with heat continuously at a constant rate and the graph shown in the adjacent figure is plotted. If L_f and L_v are latent heats of fusion and latent heats of vapourisation and S_l and S_s are specific heats of liquid and solid respectively. It can be concluded that

In Newton's experiment of cooling, the water equivalent of two similar calorimeters is 10 gm each. They are filled with 350 gm of water and 300 gm of a liquid (equal volumes) separately. The time taken by water and liquid to cool from 70^(@)C to 60^(@)C is 3 min and 95 sec respectively. The specific heat of the liquid will b

A certain mass of a solid exists at its melting temperature of 20^(@)C . When a heat Q is added (4)/(5) of the material melts. When an additional Q amount of heat is added the material transforms to its liquid state at 50^(@)C . Find the ratio of specific latent heat of fusion (in J//g ) to the specific heat capacity of the liquid (in J g^(-1) .^(@)C^(-1) ) for the material.

A calorimeter of water equivalent 5g has water of mass 55g upto a certain level Another identical calorimeter has a liquid of mass '38g' upto same level As both of them cool in the same surrounding from 50^(@)C to 46^(@)C water takes 80s where as the liquid takes 32s to cool. If the specific heat of water is 1cal//g-.^(@)C the specific heat of the liquid in cal//g-.^(@)C is .

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.

A small quantity mass m, of water at a temperature theta ("in " ^(@)C) is poured on to a larger mass M of ice which is at its melting point.
