Question: What is the work done on a gas when it is compressed from 4 L to 2 L at a constant pressure of 2 atm?

Options:

Correct Answer: 4 L·atm

Solution:

Work done (W) = P * ΔV = 2 atm * (2 L - 4 L) = 2 atm * (-2 L) = -4 L·atm (work done on the gas is positive).

What is the work done on a gas when it is compressed from 4 L to 2 L at a constant pressure of 2 atm?

What is the work done on a gas when it is compressed from 4 L to 2 L at a constant pressure of 2 atm?

Step 1: Identify the initial volume of the gas, which is 4 L.
Step 2: Identify the final volume of the gas, which is 2 L.
Step 3: Calculate the change in volume (ΔV) by subtracting the final volume from the initial volume: ΔV = 2 L - 4 L.
Step 4: This gives us ΔV = -2 L.
Step 5: Identify the constant pressure (P) at which the gas is compressed, which is 2 atm.
Step 6: Use the formula for work done (W) on the gas: W = P * ΔV.
Step 7: Substitute the values into the formula: W = 2 atm * (-2 L).
Step 8: Calculate the work done: W = -4 L·atm.
Step 9: Since the work is done on the gas, we consider it as positive work done on the gas.
