Question

Assertion - Difference in the partial pressure of a gas between two systems creates pressure gradient.
Reason - Gas moves from a region of high pressure to the region of low pressure.

• A. Both the assertion and reason are true and the reason is the correct explanation of the assertion
• B. Both assertion and reason are true but the reason is not the correct explanation of the assertion
• C. The assertion is true but the reason is false
• D. Both the assertion and reason are false

Answer 1

The correct option is A Both the assertion and reason are true and the reason is the correct explanation of the assertion

When a mixture of non reactive gases applies pressure on a system, the pressure exerted by individual gases is termed as partial pressure. A gas will move from an area where its partial pressure is higher to an area where its partial pressure is lower.
