An ideal gas, initially at a volume of 2.4 L and

pressure of 5 kPa, undergoes isothermal expansion until its volume is 6 L and its pressure

is 2 kPa.

A) Calculate the work done by the gas during

this process.

Answer in units of J.

B) find the heat added to the gas during this process.

(a) The

work doneby thegasduring this process is-10.8 J.(b) The

heatadded to thegasduring this process is10.8 J.## Work done by the gas against an external pressure

The

work doneby the gas during theisothermal expansionis calculated as follows;W(net) = ΔP x ΔV

W(net) = (2 kPa - 5 kPa) x (6L - 2.4 L)

W(net) = (-3kPa) x 3.6L

W(net) = -10.8 kPa.L

W(net) = -10.8 J

## Heat added to the gas

W = - Q

-10.8 J = -Q

Q = 10.8 J
