Two moles of ideal mono atomic gas releases 6 000 J of heat when it is compressed by an external force. A 2 000J of
work done on the gas during compression.
3. What is the change in the internal energy of the gas?
4. What is the change in the temp of the gas in Kelvin?

Expert Solution

Step 1

First law of thermodynamics:

It states that the change in internal energy ( $∆$ U) of a system is equal to the difference of the heat transfer (Q) into a system and the work (W) done by the system.

$∆ U = Q - W$

The internal energy of n moles of an ideal monatomic at temperature T is given by,

$U = \frac{3}{2} nRT R = 8.314 J \cdot K^{- 1} \cdot {mol}^{- 1} Change in internal energy with change in temperature ∆ T is ∆ U = \frac{3}{2} nR ∆ T$
