A rigid tank of volume 0.75 m3 is initially evacuated. A hole
develops in the wall, and air from the surroundings at 1 bar, 30°C
flows in until the pressure in the tank reaches 1 bar. Heat
transfer between the contents of the tank and the surroundings is
negligible. Determine the final temperature in the tank, in °C.

please show all work
A 0.5-m3 rigid tank contains refrigerant-134a
initially at 180 kPa and 40 percent quality. Heat is now
transferred to the refrigerant until the pressure reaches 700
kPa.
Determine the amount of heat transferred. (Round the final
answer to the nearest whole number.) The amount of heat transferred
is _____ kJ.
Also, show the process on a P-v diagram with
respect to saturation lines.

An old storage tank of “46” m3 stores steam at 6000 kPa and 330
°C. A crack develops at the
top wall of the tank and steam starts to leak out to the
atmosphere. An engineer realizes the
problem on time and stops the leak when the pressure inside the
tank is below 4000 kPa. If
the leak is assumed to be adiabatic and reversible,
a) What is the final temperature of the steam remained in the tank?

A 1.0 m3 tank, initially filled with 103. kPa, 300. K
air, is connected to a source of air at 1,500. kPa, 300. K. The
tank slowly fills until it is at the same pressure. If the
temperature is maintained at 300. K throughout this transient
process, what is the total heat transfer required? (You can assume
air is an ideal gas.)

A piston-cylinder device initially has a volume of 1.5 m3
containing steam at 300 kPa absolute and 150 oC. It is then heated
so it expands at constant pressure until it reaches a temperature
of 400 oC.

of energy. What boundary work is done by the cylinder, in kJ,
during the expansion? State your assumptions.

A piston–cylinder device initially contains 2 kg water in 1 m3
at 500 kPa. The system then cools down and the volume drops to half
and pressure of 300 kPa. At this state, the piston is resting on a
set of stops, and the mass of the piston is such that a pressure of
500 kPa is required to move it. (a) Show the process on a P-v, T-v
