Solution

The correct option is B faster evaporation occurs with broader surface area
We often pour tea in a saucer to cool it faster. In the saucer the surface area increases and hence it cools faster.

Q. Assertion :We are able to sip hot tea faster from a saucer than from a cup. Reason: Saucer is having more surface area than a cup, as we know that evaporation is the surface phenomenon. so, the rate of evaporation will increase with the increase in surface area.

Equal amount of tea is kept in the cup and saucer. The tea cools faster when placed in a saucer than in a cup. This phenomenon shows that rate of evaporation depends on:

Q. Assertion :An increase in surface area increases the rate of evaporation. Reason: Stronger the inter-molecular attractive forces, faster is the rate of evaporation at a given temperature.

Q. Evaporation occurs only at the surface of the liquid.

Q. Assertion :Evaporation occurs on the surface of liquid and it is a vaporization of liquid. It is a state of transition from liquid to gaseous state. Reason: Evaporation occurs when there is exposure of water to air and water molecules change into vapor and these vapors rise up and form clouds.
