The maximum wavelength in the energy distribution spectrum of sun is

4753\,\,\mathop {\text{A}}\limits^ \circ

and its temperature is

6050 \mathrm{~K}

. The temperature of star whose energy distribution shows a maximum at

9506\,\,\mathop {\text{A}}\limits^ \circ

View answer and explanation

Correct option: A

3025 \mathrm{~K}

Option A (

3025 \mathrm{~K}

) is correct because it is calculated using Wien's displacement law, which relates wavelength and temperature.

The surface of a lake is at

{1^ \circ }C

. Find the temperature of the bottom of the lake

View answer and explanation

Correct option: D

{4^ \circ }C

Option D (

{4^ \circ }C

) is correct because water has its maximum density at

{4^ \circ }C

, causing it to sink to the bottom of the lake.

A liquid having coefficient of cubical expansion

\gamma

is filled in the container having coefficient of linear expansion

\alpha

. If on heating the liquid overflows, then which of the following relations is correct?

View answer and explanation

Correct option: C

\gamma > 3 \alpha

Option C (

\gamma > 3 \alpha

) is correct because for the liquid to overflow, its volume expansion must be greater than the container's volume expansion.
