Read the following passage and answer the questions at the end of it.
Gases tend to behave non-ideally at low temperatures and high pressures, and to explain deviation from ideal behavior two types of corrections-volume correction and pressure correction are introduced.
1.Select the correct statement(S).
Read the following passage and answer the questions at the end of it.
Gases tend to behave non-ideally at low temperatures and high pressures, and to explain deviation from ideal behavior two types of corrections-volume correction and pressure correction are introduced.
1.Select the correct statement(S).
The correct options are
A Volume correction is due to finite size of molecules and pressure correction is due to force of attraction between molecules.
B At high temperatures, molecules have greater kinetic energy, and attractive forces are smaller and the behaviours of gases is close to be ideal gas behavior at high temperatures and low pressure.
C Volume correction is also called co-volume or excluded volume and is four times the volume of spherical molecules present in one mol of the gas
D More the value of Van der Waals constant 'a', better are the forces of attraction for the gas.
All the four options are correct.
