Answer:
(a) ΔU = 7.2x10²
(b) W = -5.1x10²
(c) q = 5.2x10²
Step-by-step explanation:
From the definition of power (p), we have:
(1)
where, p: is power (J/s = W (watt)) W: is work = ΔU (J) and t: is time (s)
(a) We can calculate the energy (ΔU) using equation (1):
(b) The work is related to pressure and volume by:

where p: pressure and ΔV: change in volume = V final - V initial
(c) By the definition of Energy, we can calculate q:
where Δq: is the heat transfer
