Question

In our daily chores when we mop our house floor then it becomes dry after some time. Which phenomena applies here?
A) Fermentation
B) Sublimation
C) Vaporisation
D) Evaporation

Answer 1

Hint: Evaporation is a process which changes the liquid state into gaseous state due to change (increase) in temperature or pressure. The wet mop left water droplets on the floor.

Complete step by step solution:
In our daily chores, we used to clean our floors by mopping them. In the process of mopping, we wet the mop and clean our floors. The wetted mop wets the floor. After wetting the floor, there are water droplets left on the floor. These water droplets evaporate after some time and the floor becomes dry. In this way, the floor becomes dry after mopping with a wet mop.
In sunny days, vaporisation is increased due to increase in temperature while in rainy and winter days, the vaporisation is decreased due to decrease in the temperature. Vaporisation can also be done by blowing air as it helps in vaporization by changing the pressure.

Additional Information:
Fermentation is the process in which metabolic processes produce chemical changes in organic substrates through enzymes.
Sublimation is the process in which phase of a matter is changed in a manner so that the middle phase is skipped. In this process, a substance can change from solid to gas directly.
Vaporisation is a process in which a liquid is changed into vapor. Vaporisation is increased when the temperature is increased.

Hence, option (D) is correct.

Note: Evaporation is a type of vaporisation. Evaporation is a surface phenomenon. The liquid/water can be evaporated from the surface only. The other type of vaporisation is boiling. Boiling is a bulk phenomenon. Boiling happens when the liquid reaches its boiling part and starts changing in vapours. Boiling happens when heat is given to the liquid whereas evaporation can happen when temperature is slightly changed.
