Answer:
The answer is "
"
Explanation:
For point a:
Energy balance equation:


From the above equation:

because the rate of air entering the tank that is
constant.
Since the tank was initially empty and the inlet is constant hence,
Interpolate the enthalpy between
. The surrounding air
temperature:

Substituting the value from ideal gas:

Follow the ideal gas table.
The
and between temperature
Interpolate

Substitute values from the table.
For point b:
Consider the ideal gas equation. therefore, p is pressure, V is the volume, m is mass of gas.
(M is the molar mass of the gas that is
and R is gas constant), and T is the temperature.


For point c:
Entropy is given by the following formula:

Answer: 0K
Explanation:
Absolute 0 (0K) is the point where nothing could be colder and no heat energy remains in a substance.
