molecules of an ideal gas are enclosed in cubical box at temperature 
and pressure 
. If the number of molecules in the box is tripled then new temperature and pressure become 
and 
, respectively, but the total energy of gas system remains unchanged, then
A
and 
B
and 
C
and 
D
and 
Text Solution
Verified by ExpertsThe correct answer is:
D
Since the total energy of the system remains unchanged, we have
Also, 
Therefore, 
On comparing with ideal gas equation, we get
