Why do real gases not behave exactly like ideal gases?

real gases are always hotter than ideal gases.
real gas particles have significant volume.
real gas particles have perfectly elastic collisions.
real gas particles are smaller than ideal gas particles.
real gas particles have more complex interactions than ideal gas particles.

Real gas particles have significant volume

Real gas particles have more complex interactions than ideal gas particles.

Explanation:

An ideal gas is an imaginary concept and a gas behaves almost ideally at certain pressure and temperature conditions.

The gas in real deviates from the ideal behavior as some of the assumptions made for ideal gases are not true in case of real gases.

Real gas particles have significant volume as compared to vessel unlike ideal gases.

There are interactions present in between real gas molecules at high pressure conditions.

B) Real gas particles have significant volume.

E) Real gas particles have more complex interactions than ideal gas particles.
