Question

# The graph, shown in the adjacent diagram, represents the variation of temperature of two bodies, and having same surface area, with time () due to the emission of radiation. Find the correct relation between the emissivity and absorptivity power of the two bodies.

## The correct answer is:

### Rate of cooling emissivity(e)

From the graph,

Further emissivity () absorptive power () (good absorbers are good emitters also)
