When gas molecules strike a wall their energy. changes, giving rise to a force on the wall and. leading to pressure. true or false

The given statement is true.

Explanation:

In gases, the molecules are held by weak Vander waal forces. Hence, they have high kinetic energy due to which they tend to move rapidly from one place to another leading to more number of collisions.  

Therefore, when number of collisions increases then force applied by the molecule son each other also increases.

This causes a pressure on the walls of the container as pressure is the force applied on per unit area.

Thus, we can conclude that the statement when gas molecules strike a wall their energy changes, giving rise to a force on the wall and leading to pressure, is true.

Explanation: Potassium metal is soft and white silvery lustre. it has low melting point and good conductor of heat and electricity. Copper is malleable and ductile and an extremely good conductor of heat and electricity.
