Statement I: Spraying of water causes cooling.
Statement II: For an isolated system, surface energy increase on the expense of internal energy.

A

Statement I is true, statement II is true and Statement II is a correct explanation for Statement I.

B

Statement I is true, Statement II is true and Statement II is NOT the correct explanation for Statement I.

C

Statement I is true, Statement II is false.

D

Statement I is false, Statement II is true.

Text Solution

Verified by Experts

The correct Answer is:
A
On spraying, surface area increases and hence surface energy, this increase in surface energy is on the expense of decrease in internal energy and hence temperature decreases.
