Question

A cylinder contains 0.150 mol of an ideal gas. The cylinder has a movable piston on top, which is free to slide up and down, and which keeps the gas pressure constant. The piston's mass is 8,000 g and its circular contact area with the gas is 5.00 cm².

(a)

Find the work (in J) done on the gas as the temperature of the gas is raised from 10.0°C to 285°C.

(b)

What does the sign of your answer to part (a) indicate?

- The gas does positive work on its surroundings.

- The surroundings do positive work on the gas.

- There is no work done, by the gas or the surroundings.

Expert Solution

Step 1

Formula for Work done is, W = $P ∆ V = P (V_{2} - V_{1}) = P (\frac{n R T_{2}}{P} - \frac{n R T_{1}}{P}) = n R (T_{2} - T_{1})$

GIVEN:

$n = 0.150 m o l m = 8000 g a r e a = 5 c m^{2} T_{1} = 10 ° C; T_{2} = 285 ° C$
