-155 J of work is done on a gas (meaning 155 J of work is done by that gas) and changes the volume by 0.250 L. What is the external pressure? Assume that the external pressure is constant over the change in volume. Give the answer to three significant figures.

Step 1
Step 1: The work done on the gas is given by the equation: $$W = -P\Delta V$$ where $W$ is the work done, $P$ is the external pressure, and $\Delta V$ is the change in volume. Show more…

A gas expands against a constant external pressure of 1.20 atm. The initial volume of the gas is 0.250 L and the final volume is 1.95 L. Calculate the work done by the gas.

The piston has an external pressure of 1.00 atm. How much work has been done if the cylinder goes from a volume of 0.150 liters to 0.450 liters? Express your answer with the appropriate units.

A cylinder containing a gas is equipped with a piston and expands against an external pressure of 1.00 atm. If the initial volume is 0.250 L and the final volume is 2.50 L, how much work (in J) is done by the gas? 101.3 J = 1 L-atm
