Physics Question on kinetic theory
Ideal gas and real gas have major difference of
A
phase transition
B
temperature
C
pressure
D
None of the above
Answer
pressure
Explanation
Solution
No attractive or repulsive force acts between gas molecules in an ideal gas whereas for a real gas due to intermolecular force in real gases. Molecules do not exert that force on the wall which they would have exerted in the absence of intermolecular force. Therefore, the observed the observed pressure p of the gas will be less than that present in the absence of intermolecular force. Hence, the attractive becomes (p+V2a).
