Questions & Step-by-Step Solutions

What is the work done by a gas that expands isothermally from volume V1 to V2 at temperature T?
  • Step 1: Understand that isothermal means the temperature (T) remains constant during the expansion.
  • Step 2: Identify the initial volume (V1) and the final volume (V2) of the gas.
  • Step 3: Recognize that 'n' represents the number of moles of gas and 'R' is the ideal gas constant.
  • Step 4: Use the formula for work done during isothermal expansion, which is W = nRT ln(V2/V1).
  • Step 5: Plug in the values of n, R, T, V2, and V1 into the formula to calculate the work done (W).
