R always starts at pressure 1.50 ✕ 105 Pa and temperature 250 K. For each of the following processes, determine the final pressure (Pf, in kPa), the final volume (Vf, in L), the final temperature (Tf, in K), the change in internal energy of the gas (ΔEint, in J), the energy added to the gas by heat (Q, in J), and the work done on the gas (W, in J). (Due to the nature of this problem, do not use rounded intermediate values in your calculations—including answers submitted in WebAssign.)

(a)

The gas is heated at constant pressure to 370 K.

Pf= kPa

Vf=

LTf=

KΔEint=

JQ= J

W= J

(b)

The gas is heated at constant volume to 370 K.

Pf= kPaVf= LTf= KΔEint= JQ= JW= J

(c)

The gas is compressed at constant temperature to 195 kPa.

Pf= kPaVf= LTf= KΔEint= JQ= JW= J

(d)

The gas is compressed adiabatically to 195 kPa.

Pf= kPaVf= LTf= KΔEint= JQ= JW= J
