Question

Which one of the following is true about the motion of gaseous particles?

• A. The particles hit each other and also the walls of the container.
• B. The particles do not hit each other; they only hit the walls of the container.
• C. The particles hit each other but they do not hit the walls of the container.
• D. The particles neither hit each other nor the walls of the container

Answer 1

The correct option is A The particles hit each other and also the walls of the container.

$\bullet$ In the gaseous state, the particles move about randomly at high speed. Due to this random movement, the particles hit each other and also the walls of the container.
$\bullet$The pressure exerted by the gas is because of this force exerted by gas particles per unit area on the walls of the container.
