Consider a process that occurs at constant volume.

The volume of a gas in a cylinder is $4\mathrm{.}20$ L

$,$ the temperature is $26\mathrm{.}0\backslash$deg C

and before the position of the piston was fixed, the system was in equilibrium with an external pressure of $1\mathrm{.}2$ bar $($given by the sum of a $1$ bar atmospheric pressure and a $0\mathrm{.}2$ bar pressure due to a brick that rests on top of the piston$).$ The gas is heated slowly until the temperature reaches $51\mathrm{.}2\backslash$deg C

$.$ Assume the gas behaves ideally, and its heat capacity at constant volume is: CV$,$m$=20\mathrm{.}79$J$/($K$.$mol$)$ What is the value of w$?$ What is the value of q$?$ Calculate $\backslash$Delta U Calculate $\backslash$Delta H

What can you say about the molecules that make up the gas?

The molecules of the gas have a linear shape.

It is a monoatomic gas.

The molecules of the gas consist of at least $2$ atoms.

The molecules of the gas have a nonlinear shape.

The molecules of the gas consist of at least $3$ atoms.
