You hold a 50-g sphere of copper (c = 0.4j/(g*c)) in one hand and a 25-g sphere of aluminum ( = 0.9 j/(g*c)) in the other hand. if both absorb energy at the same rate, which will come to your body temperature first and why?

rate of change in temperature of copper is more than the rate of change in temperature of aluminium.

so here copper will reach to our body temperature first

Explanation:

As we know that rate of energy absorb by the two sphere is same

so here we will have

now for copper sphere we will have

now for Aluminium sphere we will have

So rate of change in temperature of copper is more than the rate of change in temperature of aluminium.

so here copper will reach to our body temperature first
