Question

Capacity of three sphere of iron, copper and
aluminium of same radius are C1 , C2 and C3
then –
1)C2 > C1 > C3 2)C3 > C2 > C1
3)C1 > C2 > C3 4)C1 = C2 = C3

Answer 1

Answer:

Statement-1: Two metallic spheres of same size, one of copper and the other of aluminium, heated to the same temperature, will cool at the same rate when they are suspended in the same enclosure. <br> Statement-2: The rate of cooling of a body depends on the excees of temperature of the body over the surroundings.

Answer 2

Answer:

As c=4πεr

and radius of all spheres are same so c1=c2=c3
