Question

A certain amount of ideal monatomic gas is maintained at constant volume as it is cooled from 455 K to 405 K. This feat is accomplished by removing 400J of energy (as heat flow) from the gas. How much work is done by the gas during this process?

Answer 1

Zero (0) Joules

Step-by-step explanation:

Work done in this system is given by

First law of thermodynamics

`W=P\Delta V`

Where,

P = Pressure

`\Delta V` = Change in volume

Here, the volume is not changing i.e.,
`\Delta V=0`. Only the temperature is changing here, the pressure and volume remains constant.

So, the work done will be zero Joules
