The temperature of bodies 
and 
vary with time as shown in the figure. If emissivity of bodies 
and 
are 
and absorptive powers are 
and A y (assume other conditions are identical for both): then:
A
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
A
Rate of cooling 
∝ emissivity (e)
From the graph,
∴ e y > e x
Further emissivity (e) ∝ absorptive power (good absorbers are good emitters also)
∴ a y > a x
