Calculate the work for the expansion of CO₂ from 1.0 to 4.7 liters against a pressure of 1.0 atm at constant temperature.

Question

Quizplus · Accepted Answer

The work done for the expansion of a gas at constant temperature and pressure is given by the formula: 
Work = -PΔV, where P is the pressure, ΔV is the change in volume, and the negative sign indicates that work is done on the system. 
In this case, ΔV = 4.7 L - 1.0 L = 3.7 L, and P = 1.0 atm. 
Substituting into the formula, we get: 
Work = - (1.0 atm) × (3.7 L) = -3.7 L·atm
Note that the negative sign indicates that work is done on the system, which makes sense because the gas is expanding against an external pressure. Therefore, the correct answer is (D).
