Heat and Thermodynamics 5 Question 52
53. At two moles of an ideal monoatomic gas occupy a volume . The gas expands adiabatically to a volume .
Calculate
(1996, 5M)
(a) the final temperature of the gas,
(b) change in its internal energy,
(c) the work done by the gas during this process.
Show Answer
Answer:
Correct Answer: 53. (a)
Solution:
- Given,
(a) Final temperature
In adiabatic process,
or
(b) Change in internal energy,
(c) Work done
Process is adiabatic, therefore
and from first law of thermodynamics,
