Read the problem carefully at least once. $($cont$.)$

We solve the ideal gas equation in the initial state, $P_i{V}_i=nR{T}_i,$ to obtain

$n=\frac{P_i{V}_i}{R{T}_i}=\frac{(3\mathrm{.}65{10}^5(Pa))(4\mathrm{.}25{10}^{-4}{m}^3)}{(8\mathrm{.}31(\frac{J}{m}ol*(K)))(303(K))}=0\mathrm{.}0616$mol

The canister contains $n=0\mathrm{.}0616$ moles of the diatomic gas.

Identify the thermodynamic process.

As the gas changes from the initial to the final state, no thermal energy is transferred into or out of it$.$

By what thermodynamic process does the gas change from the initial to the final state?

isovolumetric

isothermal

adiabatic

isobaric

none of the above
