Assertion : Bodies radiate heat at all t...

Assertion : Bodies radiate heat at all temperatures.
Reason : Rate of radiation of heat is proportional to the fourth power of absolute temperature.

A

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

B

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

C

If assertion is true but reason is false.

D

If assertion is false but reason is true.

Text Solution

Verified by Experts

The correct Answer is:
D
Assertion is false because at absolute zero (0 K), heat is neither radiated nor absorbed. Reason is the statement of Stefan’s law, as `E prop T^4`

The famous Stefan's law of radiation states that the rate of emission of thermal radiation per unit by a black body is proportional to area and fourth power of its absolute temperature that is Q=sigmaAT^(4) where A = area, T = temperature and sigma is a universal constant. In the 'energy-length-time temperature' (E-L-T-K) system the dimension of sigma is

Statement-1: When the temperature of a black body is doubled from t^(@)C to 2t^(@)C , the radiant power becomes 16 times. Statement-2: The radiant power of a body is proportional to fourth power of absolute temperature.

Assertion : For higher temperature, the peak emission wavelength of a black body shifts to lower wavelengths. Reason : Peak emission wavelength of a black body is proportional to the fourth power of temperature.

The amount of thermal radiation energy emitted from the surface of a body is found to be proportional to the ........ power of the absolute temperature of the body.
