Observe the graph given below and answer the following questions: During vaporization of a liquid, certain amount of heat is absorbed without any change in temperature. Which part of the graph shows this change?

Observe the graph given below and answer the following questions: During melting of a solid, certain amount of heat is absorbed without any change in temperature. Which part of the graph shows this change?

The amount of heat energy required to convert 1 kg of ice at -10^@ C to water at 100^@ C is 7,77,000 J. Calculate the specific latent heat of ice. Specific heat capacity of ice = 2100 J kg^(-1) K^(-1) , specific heat capacity of water = 4200 J kg^(-1) K^(-1) .

Figure shows two processes a and b for a given sample of gas. If DeltaQ_1, DeltaQ_2 are the amount of heat absorbed by the systemin the two cases , and DeltaU_1, DeltaU_2 are changes ininternal energy respeclively, then

Part of the small and large intestine absorbs water and via feces, it is expected. Arrange these in order of the amount of water absorbed or secreted from greatest to smallest.

Following figure shows two process A and B for a gas. If Delta Q_(A) and Delta Q_(B) are the amount of heat absorbed by the system in two case, and Delta U_(A) and Delta U_(B) are changes in internal energies, respectively, then :
