Question

If gas particles start colliding with the walls of their metallic container with increase force what is their direct effect

Answer 1

I believe your answer would be higher gas pressure.

Answer 2

Answer: The increase in force will directly effect the pressure exerted by the gas that is high pressure of the gas.

Explanation:

The pressure is defined as force applied per unit area.

$Pressure=\frac{Force}{Area}$

$Pressure\propto Force$

If the gas particles colliding with the walls of container with increase in force then the pressure of the gas exerted by the particles of the gas will also get increased.
