Question

Which phenomenon occurs during the following changes?

(i) Formation of clouds

(ii) Drying of wet clothes,

(iii) wax melts in the sun

(iv) Size of napthalene balls decreases.

Answer 1

(i) Formation of clouds takes place because of condensation. Condensation takes place when the water that has evaporated changes back to liquid state and condenses in the upper layers of the atmosphere forming clouds.

(ii) Drying of wet clothes takes place because of evaporation. Evaporation is the process in which water changes to its vapour state. When wet clothes are put for drying, the heat changes the water into its vapour or gas state.

(iii) Wax melts in the sun because of melting. Melting takes place when a solid changes to its liquid state because of high heat.

(iv) Sublimation causes the size of naphthalene balls to decrease. Sublimation takes place when solid changes to its vapour state directly.
