Alead block of mass 6.6 kg is originally at a temperature of 26°c and 1 atm. it is then heated to a temperature of 68°c without any change in pressure. the specific heat of lead is 128 j/(kg.°c), its density is 1.13 104 kg/m^3, and the coefficient of linear expansion is 29 ✕ 10^−6 /°c. (a) determine the work done by the lead block.
(b) how much heat energy is transferred during this process?
(c) what is the increase in internal energy of the system?
