Assertion : While measuring the thermal conductivity of liquid experimentally, the upper layer is kept hot and the lower layer kept cold.
Reason : This avoids heating of liquid by convection.

A

If both assertion and reason are true and reason is the correct explanation of assertion.

B

If both assertion and reason are true but reason is not the correct explanation of assertion.

C

If assertion is true but reason is false.

D

If both assertion and reason are false.

Text Solution

Verified by Experts

The correct Answer is:
A
We know that to measure thermal conductivity of liquids experimentally, they must be heated from the top i.e., upper layer is kept hot cold, so as to prevent convection in liquids.

A heat flux passes through a gas from a heated plate with a temperature T_1 to a cold plate with a temperature T_2 . The linear dimensions of the plates are large compared to the distance between them. Is the temperature gradient the same along the entire heat flux? Why when measuring the thermal conductivity coefficient must we place the plates horizontally, with the plate with the higher temperature placed above the one with the lower temperature?

Assertion : The viscosity of liquid increases rapidly with rise of temperature. Reason : Viscosity of a liquid is the property of the liquid by virtue of which it opposes the relative motion amongst its different layers.
