Identify false statement about real gas from following .
Options
- AIt obeys Boyle's & Charles' law at low pressure and high temperature.
- BIts molecules are not perfectly elastic.
- CIn real gas, intermolecular attraction is present.
- DIt can not liquify even at low temperature.
Correct answer
D. It can not liquify even at low temperature.
Step-by-step solution
Real gases behave like ideal gases at high temperatures and low pressures, so they obey Boyle's and Charles' laws under these conditions. Unlike the theoretical model of an ideal gas, where molecules are assumed to be rigid spheres that undergo perfectly elastic collisions , real gas molecules have internal structures and exert intermolecular forces on each other. When real gas molecules collide, some of their translational kinetic energy can be temporarily converted into internal energy, meaning the collisions the
