A certain amount of ideal monatomic gas is maintained at constant volume as it is cooled from 455K to 405 K. This feat is accomplished by removing 400 J of heat from the gas. How much work is done by the gas during this process? The ideal gas constant is R = 8.314 J/mol • K.

Answer:

[tex]W=0[/tex]

Explanation:

The work done by the gas is defined as:

[tex]W=P\Delta V[/tex]

Where P is the presion and [tex]\Delta V[/tex] is the volume change. Since the gas is maintained at constant volume, we have [tex]\Delta V=0[/tex]. So:

[tex]W=P(0)\\W=0[/tex]

So, the heat is equal to the change in the internal energy of the gas.
