Drag acts in a direction opposite to the motion, and also lift action perpendicular come the motion.

A frictionless piston-cylinder includes carbon dioxide gas (CO2) originally at 500oC and also 2 MPa. The mechanism is o3 cooled in one iso
civicpride-kusatsu.net:
(a) The reduced pressure is 0.2711 MPa
The decreased temperature is 2.54 K
(b) The initial volume that the piston is roughly 0.806 m³
(c) The massive of CO₂ is around 16.9884 kg
(d) The job-related done, W is around 388.023 kJ
(e) The warm transfer is roughly -2,650.1904 kJ
Explanation:
The early stage temperature of the piston-cylinder, T₁ = 500°C = 773.15 K
The initial push of the gas, P₁ = 2 MPa
The last temperature that the gas, T₂ = 350°C
The last volume the the gas = 1 m³
(a) because that an isobaric process, us have;
The reduced pressure,

The an essential pressure of carbon dioxide,


The reduced pressure,

The an essential temperature,

The diminished temperature,


Therefore,

The reduced temperature,

(b) The early stage volume that the piston, V₁ = (V₂/T₂) × T₁
The initial volume the the piston, V₁ ≈ 0.806 m³
(c) The variety of moles the CO₂ in the cylinder, "n", is provided according come the following formula;
n = P·V/(T·R)
The global gas constant, n = (2 × 10⁶Pa × 1 m³)/(623.15 K × 8.3145 J/(mol·K)) ≈ 386.0124 moles
