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

Answer:

Zero (0) Joules

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
