Final answer:
The work done by the gas during expansion can be calculated using the formula Work = -P∆V. Given the specific values for volume and pressure, the work done is -6.0 L atm.
Step-by-step explanation:
The work done by a gas during expansion can be calculated using the formula:
Work = -P∆V
Where P is the pressure and ∆V is the change in volume. Given that the gas expands from 2.0L to 5.0L against a pressure of 2.0 atm, we can substitute the values into the formula:
Work = -(2.0 atm)(5.0 L - 2.0 L) = -6.0 L atm
Therefore, the work done by the gas during the expansion is -6.0 L atm.
