NEET Physics Question - Thermal Physics

Assertion (A): Water can be made to boil without heating.

Reason (R): Boiling point of water is lowered by decreasing pressure.

Both (A) & (R) are true and the (R) is the correct explanation of the (A)

Both (A) & (R) are true but the (R) is not the correct explanation of the (A)

(A) is true but (R) is false

Both (A) and (R) are false

Solution:

Boiling occurs when vapor pressure equals external pressure. Reducing external pressure lowers the boiling point of water. Thus, water can be made to boil at room temperature or even lower without external heating. Both (A) and (R) are true, and (R) correctly explains (A).
