Questions & Step-by-Step Solutions
What is the work done by an ideal gas during an isothermal expansion from volume V1 to V2 at temperature T? (2021)
Step 1: Understand that an isothermal expansion means the gas expands at a constant temperature (T).
Step 2: Recognize that during this process, the gas does work on its surroundings as it expands from an initial volume (V1) to a final volume (V2).
Step 3: Recall the formula for work done (W) by an ideal gas during isothermal expansion, which is W = nRT ln(V2/V1).
Step 4: Identify the variables in the formula: n is the number of moles of gas, R is the ideal gas constant, T is the temperature in Kelvin, V2 is the final volume, and V1 is the initial volume.
Step 5: Plug in the values for n, R, T, V2, and V1 into the formula to calculate the work done.
