Question

A chamber fitted with a piston can be controlled to keep the pressure in the chamber constant as the piston moves up and down to increase or decrease the chamber volume. The chamber contains an ideal gas at 296 K and 1.00 atm. What is the work done on the gas as the piston compresses it from 1.00 L to 0.633 L

Answer 1

Answer:

The work done on the gas is 37 J.

Explanation:

let P be the pressure in the chamber.

let V1 be the initial volume of the chamber.

let V2 be the final volume of the chamber.

then, the work done on the gas is given by:

W = P(V2 - V1)

    = (1×10^5)(1 - 0.633)×10^-3

    = 37 J

Therefore, the work done on the gas is 37 J.
