Heat and Thermodynamics 4 Question 36

38. During an experiment, an ideal gas is found to obey an additional law p2V= constant. The gas is initially at a temperature T and volume V. When it expands to a volume 2V, the temperature becomes

(1987,2M)

Show Answer

Solution:

Vp2= constant 

Putting, p=nRTV, we have T2V= constant

 or TV

So, if V is doubled, T becomes 2 times.
