When p calories of heat is given to a body, it absorbs q calories, then the absorbtion power of body will be :-

If 'p' calorie of heat energy is incident on a body and absorbs 'q' calories its coefficient of absorption is .

If 'p' calorie of heat energy is incident on a body and absorbs 'q' calories of heat absorbed then its coefficient of absorption is .

If 'p' calorie of heat energy is incident on a body and absorbs 'q' calories of heat absorbed then its coefficient of absorption is .

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 of heat surface of a body is 0.68. When 100 calories of heat is incident on the body, 27 calories are reflected from the surface. Find the coefficient of transmission of the body.

Define one kilo-calorie of heat.

Relate on calorie of heat in terms of joule.

The SI unit of heat is 'calorie'.

The SI unit of heat is 'calorie'.

What is emissivity of a body ? How it is related to absorbing power ?
