A block of copper and a block of lead are heated. The internal energy of each block increases by the same amount. The block of copper has a lower thermal capacity than the block of lead. Which conclusion can be made from this information? A The temperature increase of the copper is greater than the temperature increase of the lead. B The temperature increase of the copper is the same as the temperature increase of the lead. C The temperature increase of the copper is less than the temperature increase of the lead. D The melting point of copper is lower than the melting point of lead.

Answer:
Temperature increase of. Copper is greater than that of lead option A
Explanation:
As thermal capacity of lead c2 is greater than that of copper c1 and internal energy change for both block is the same so now it depends on temperature change .....
Internal energy is proportional to heat capacity*change in temperature
So c1*T1=c2*T2
As c1<c2
Therefore T1>T2
Where T1 and T2is change in temperature of copper and lead respectively
