Question

Assertion: Gasses obey Boyle's law at high temperature and low pressure only.

Reason: At low pressure and high temperature, gasses would behave like ideal gases.

• A. Both assertion (A) and reason (R) are correct and R gives the correct explanation
• B. Both assertion (A) and reason (R) are correct but R does give the correct explanation
• C. A is true but R is false
• D. A is false but R is true

Answer 1

The correct option is A Both assertion (A) and reason (R) are correct and R gives the correct explanation

Due to non idealities gases obeys vander waals equation instead of ideal equation and at high temperature and low pressure vander waals equation becomes ideal gas equation by taking approximations. therefore, at high temperatur and low pressure gases obeys boyles law and behaves ideally.
assertion is true reason is true and reason is correct explanation of assertion.
option(A)
