1.	If the work done by a system on its surroundings is 100 J and the increase in the internal energy of the system is 100 cal, what must be the heat supplied to the system? (Given : J = 4.186J/cal)
Answer» Data : W = 100 J, ∆ U = 100 cal, J = 4.186 J / cal The heat supplied to the system, Q = ∆ U + W = (100 cal) (4.186 J/cal) + 100 J = 418.6J + 100J = 518.6 J

If the work done by a system on its surroundings is 100 J and the increase in the internal energy of the system is 100 cal, what must be the heat supplied to the system? (Given : J = 4.186J/cal)

Answer»

Data : W = 100 J, ∆ U = 100 cal, J = 4.186 J / cal

The heat supplied to the system,

Q = ∆ U + W = (100 cal) (4.186 J/cal) + 100 J = 418.6J + 100J = 518.6 J
