If a contained ideal gas decreases the volume by a factor of two and then triples the temperature, what happens to the pressure?

Solutions

Expert Solution


let P1 is the initial pressure
V1 is the initial volume
T1 is the initial temeperature

final volume, V2 = V1/2

final temperature, T2 = 3*T1

P2 = ?


use, idela gas equation, P*V = n*R*T

P*V/T = n*R

P*V/T = constant

so, P2*V2/T2 = P1*V1/T1

P2 = P1*(V1/V2)*(T2/T1)

= P1*(V1/(V1/2))*(3*T1/T1)

= P1*2*3

= 6*P1

so, pressure becomes 6 times

. An ideal gas initially contained at 1 bar and 25ºC, is compressed to a final state of 5 bar and 25ºC. Although the initial and final temperatures are the same, the process is NOT isothermal. Rather, the change of state occurs in two steps. First, the gas is cooled at constant pressure (i.e., 1 bar). Second, the gas is heated at constant volume. Please calculate Q, W, DU, and DH for the two steps. Note: Cp*=29.1 J/mol/K, and 1...
