Question

(i) a constant-temperature expansion that triples its volume

Your response differs from the correct answer by more than 100%. kPa

Your response differs significantly from the correct answer. Rework your solution from the beginning and check each step carefully. m3

(ii) a constant-pressure compression to its initial volume
kPa
m3

(iii) a constant-volume increase in pressure to its initial pressure
kPa
m3

At the end of these three processes, the gas is back at its initial pressure, volume, and temperature. Plot these processes on a pressure-versus-volume graph, showing the values of P and V at the end points of each process.

Explanation / Answer

i) 60 kPa; 3.3x10^-3 m^3; 350 K
ii)60 kPa; 1.1x10^-3 m^3; 116.67 K
iii)180 kPa; 1.1x10^-3 m^3; 350 K

i) is rectangular hyperbola from (P, V) point to (P/3, 3V) point;
ii) is parallel to v axis path from (P/3, 3V) to(P/3, V)
iii) vertical path from (P/3, V) to (P, V)
Temperature cannot be shown on this P-V graph. For i) it is constant, for ii) it is linearly decreasing to half its value and in iii) it is linearly increasing to its original value.
