Answer:
Part a: <em>The total amount of energy transfer by the work done is 54.81 kJ.</em>
Part b: <em>The total amount of energy transfer by the heat is 54.81 kJ</em>
Explanation:
Mass of Carbon Dioxide is given as m1=3 kg
Pressure is given as P1=3 bar =300 kPA
Volume is given as V1=0.5 m^3
Pressure in tank 2 is given as P2=2 bar=200 kPa
T=290 K
Now the Molecular weight of is given as
M=44 kg/kmol
the gas constant is given as
Volume of the tank is given as
Final mass is given as
Mass of the CO2 moved to the cylinder
The initial mass in the cylinder is given as
The mass after the process is
Now the volume 2 of the cylinder is given as
Part a:
So the Work done is given as
<em>The total amount of energy transfer by the work done is 54.81 kJ.</em>
Part b:
The total energy transfer by heat is given as
As the temperature is constant thus change in internal energy is 0.
<em>The total amount of energy transfer by the heat is 54.81 kJ</em>
