Two reversible engine operate between thermal reservoirs at 1200 K, T2K and 300 K such that 1st engine receives heat from 1200 K reservoir and rejects heat to thermal reservoir at T2K, while the 2nd engine receives heat from thermal reservoir at T2K and rejects heat to the thermal reservoir at 300 K. Calculate T2 in K If the efficiency of both the engines is equal.

(a) Show from first principles, that when the surface area of a system, subject to a surface tension ¶, changes by a small amount dA, the work done by the system is (-¶dA)
(b). A bubble rose from the bottom of a lake to near its surface. The
bubble was initially 1 cm in diameter, at a pressure of 2 bar. The final pressure
experienced by the bubble was 1 bar. The initial as well as the final shape of the bubble was spherical, and its volume varied inversely to the pressure. Determine
the net work done by the bubble. For water, ¶ = 0.073 N/m. Which additional
assumptions did you make? Please comment on your answer.

A system containing m = 5 kg of a liquid is stirred with a torque of T = 0.3 kgf-m
at a speed of X = 1000 RPM for t = 24 hr. The system meanwhile expands from
V1= 1m³ to V2 = 2m³ against a constant pressure of p = 4 kgf/cm². Determine
the net work done (W) in kJ.

Two kg of a substance undergoes the specified process in a Cylinder-piston arrangement:
p1 = 6 bar; V1 = 0.2 m³; p2 = 2 bar; V2 = 0.6 m³,
Determine the work done (W) in each case.
(a) p varies as a linear function of V. (b) pV = a constant. (C) p remains constant till the volume reaches V3 = 0.3m³; pV^n = a Constant after that4 (You have to determine the value of n.)
