Question

Part 1- An ideal gas, initially at a volume of 1.71429 L and pressure of 7 kPa, undergoes isothermal expansion until its volume is 6 L and its pressure is 2 kPa. Calculate the work done by the gas during this process. Answer in units of J.
Part 2- Find the heat added to the gas during this process.
Answer in units of J.

Answer 1

Part 1- The work done by the gas during this process will be 5.65 ×10⁻³ kJ.

Part 2-The heat added to the gas during this process will be 5.65 ×10×10⁻³ kJ.

What is work done by the gas?

Work is the product of pressure p and volumes V during a volume change for such a gas. The work seems to be the area under the curve that indicates how the state changes.

The work done under the isothermal process is;

$\rm W= P_1V_1 log_e(\frac{P_1}{P_2} )\\\\ W= 7 \times 1.71429 \times 10^{-3} log_e(\frac{7 }{2} )\\\\\ W= 0.0044 \ kJ$

For the isothermal process;

ΔU=0

$\rm \triangle Q = \triangle E + \triangle W \\\\ Q = 0 + 5.65 \times 10^{-3}\\\\ Q = 5.65 \TIMES 10^{-3} \ kJ$

Hence, the work done, and the heat added by the gas during this process will be 5.65 ×10⁻³ kJ and 5.65 ×10×10⁻³ kJ respectively.
