Each question contains STATEMENT-I(Assertion) and STATEMENT-2(Reason). Read the statement carefully and mark the correct answer according to the instruction given below: STATEMENT - 1 : An increase in surface area increases the rate of evaporation. STATEMENT - 2 : Stronger the intermolecular attaction force, faster is the rate of evaporation at a given temperature.

A child running a temperature of 101^F is given and antipyrin (i.e. a madicine that lowers fever) which cause an increase in the rate of evaporation of sweat from his body. If the fever is brought down to 98^@F in 20 min., what is the averatge rate of extra evaporation caused, by the drug ? Assume the evaporation mechanism to the only way by which heat is lost. The mass of the child is 30 kg. The specific heat of human body is approximately the same as that of water and latent heat of evaporation of water at that temperature is about 580 cal. g^(-1).

Name six factors which affect the rate of evaporation.

Explain what do you understand by evaporation. Discuss the factors which influence the rate of evaporation of a liquid.

................ (Less/More) the amount of water present in the atmosphere, less will be the rate of evaporation.

A liquid is in equilibrium with its vapour in a sealed container at a fixed temperature. The volume of the container is suddenly increased. a. what is the initial effect of the change on vapour pressure? b. How do rates of evaporation and condensation change initially? c. What happens when equilibrium is restored finally and what will be the final vapour pressure?

Arrange the following liquids in the decreasing order of the rate of evaporation : water, ethyl alcohol, benzene, .

Write two factors on which the rate of evaporation depends.

Higher the initial temperature of the liquid, more is the rate of evaporation of liquid.
