What is not true for an ideal gas?

• Gas molecules have forces of attraction for each other

• Collisions between molecules do not involve the transfer of energy

• Gas molecules do not occupy any volume

• Gas molecules have primarily translational motion

Which of the following assumptions is incorrect according to kinetic theory of gases?

• Particles of a gas move in all possible directions in straight lines

• The actual volume of the gas is negligible in comparison to the empty space between them

• There is no force of attraction between the particles of a gas at ordinary temperatures and pressures

• All the partcles, at any particular time have the same speed and same kinetic energy
