Question

Pressure exerted by a gas is equal to _______________.

• A. force exerted per unit time
• B. force exerted per unit area of walls of container
• C. area of walls of container per unit of force
• D. None of the above

Answer 1

The correct option is B force exerted per unit area of walls of container

The pressure exerted by a gas is equal to force on the walls of the container per unit area of walls of the container.

It can be written as: $P=\frac{F}{A}$

Here, $P=$ Pressure exerted by a gas on the walls of the container.

$A=$ Area of the walls of the container.

$F=$ Force on the walls of the container

Hence the option B is correct.
