Equal masses of two liquids A and B contained in vessels of negligible heat capacity are supplied heat at the same rate. The temperature-time graphs for the liquids are shown in the figure. If S represents specific heat and L represents latent heat of liquid, then

A solid material is supplied heat at a constant rate. The temperature of material is changing with heat input as shown in the figure. What does the slope of DE represent ?

Heat is supplied to a ice at a constant rate Temperature variation with time is as shown in figure. Then –

Cooling curves are drawn for three liquids a,b,c, shown in fig. for which liquid specific heat is least?

A solid substance is at 30^(@)C . To this substance heat energy is supplied at a constant rate. Then temperature versus time graph is as shown in the figure. The substance is in liquid state for the portion (of the graph)

A source of heat supplies heat at constant rate to a solid cube. The variatiion of the temperature of the cube with heat supplied is shown in figure. The portion DE of the graph represents conversion of

The temperature of a hot liquid in a container of negligible heat capacity falls at the rate of 3K//min due to heat emission to the surroundings, just before it begins to solidify. The temperature then remains constant for 30min , by the time the liquid has all solidfied. Find the ratio of specific heat capacity of liquid to specific latent heat of fusion.

Equal masses of two liquid- one at 20^(@)C and other at 40^(@)C are mixed together.The temperature of the mixture is 32^(@)C . The ratio of their specific heats is
