Statement I: The bulb of one thermometer is spherical while that of the other is cylindrical . Both have equal amounts of mercury. The response of the cylindrical bulb thermometer will be quicker.
Statement II: Heat conduction in a body is directly proportional to cross-sectional area.

A

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

B

Statement I is true, statement II is true and statement II 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
Both are true and Statement II explains Statement I because for same volume surface area of the cylindrical bulb will be more.
