Questions & Step-by-Step Solutions

What is the work done by an ideal gas during an isothermal expansion from volume Vi to Vf?
  • Step 1: Understand that an isothermal expansion means the temperature of the gas remains constant.
  • Step 2: Know that 'n' represents the number of moles of the gas, 'R' is the ideal gas constant, and 'T' is the absolute temperature in Kelvin.
  • Step 3: Identify the initial volume (Vi) and the final volume (Vf) of the gas.
  • Step 4: Use the formula for work done during isothermal expansion, which is W = nRT ln(Vf/Vi).
  • Step 5: Calculate the natural logarithm of the ratio of the final volume to the initial volume, ln(Vf/Vi).
  • Step 6: Multiply the result from Step 5 by n, R, and T to find the total work done (W).
