Question
A machine compresses 10 mole/minute of helium, modelled as an ideal gas, from 1 to $10^6$ Pa pressure. What rate of flow of cooling water, initially at $290 \mathrm{~K}$, is needed if the compression is to be made isothermal at $300 \mathrm{~K}$ ?
Step 1
We can use the ideal gas law to calculate the initial volume of the helium gas. The ideal gas law is given by: PV = nRT Where: P = pressure (in Pa) V = volume (in m^3) n = number of moles R = ideal gas constant (8.314 J/(mol·K)) T = temperature (in K) We are Show more…

One mole of an ideal monoatomic gas is compressed from 2.0 to 6.0 atm, while being cooled from 400 to 300 K. Calculate the values of ΔU, ΔH, and ΔS for the process.
Ten moles of an ideal gas at constant temperature $600 \mathrm{~K}$ is compressed from $100 \mathrm{~L}$ to $10 \mathrm{~L}$. The work done in the process is (a) $4.11 \times 10^{4} \mathrm{~J}$ (b) $-4.11 \times 10^{4} \mathrm{~J}$ (c) $11.4 \times 10^{4} \mathrm{~J}$ (d) $-11.4 \times 10^{4} \mathrm{~J}$
