Answer 1

$\large\color{lime}\boxed{\colorbox{black}{Answer : - }}$

★ The pressure of a gas is directly proportional to the force created by the bombardment of molecules on the walls of the container.

★ The speed of a molecule moving towards the wall of the container is reduced by the attractive forces exerted by its neighbours.

★ Hence, the measured gas pressure is lower than the ideal pressure of the gas.

★ Hence, van der Waals introduced a correction term to this effect.

Answer 2

Answer:

Pressure-correction method is a class of methods used in computational fluid dynamics for numerically solving the Navier-Stokes equations normally for incompressible flows.
