Describe an activity to demonstrate that a black object absorbs more heat than a white object .

1000 calories of radiant heat is incident on a body. If the body absorbs 400 calories of heat, find the coefficient of emission of the body.

The coefficient of absorption and reflection on the surface of the thin plate are 0.74 and 0.22, respectively. If 184 calories of radiant heat is incident on the surface of the plate, find the quantities of heat absorbed, reflected, and transmitted.

Which of the following process absorbs heat and which one releases heat ? Condensation of water vapour

Black substance absorbs and lose heat radiations faster

Assertion : All bodies emit radiant energy whether they are solid, liquid or gases. Reason : Black bodies absorb and emit radiant energy better than bodies of lighter colours.
