Question

Assertion: During rapid pumping of air in tyres, air inside the tyre is hotter than atmospheric air.
Reason: Adiabatic process occurs at very high rate.

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

Answer 1

Answer: (A)

Pumping air inside the tyre is an adiabatic process, as it's very quick and compressed air inserts inside the tyre. Therefore, assertion and reason both are correct and reason is the correct explanation.
