Question

Assertion: P-V graph (at constant temperature) for ideal gas is rectangular parabola

Reason: Ideal gas obeys Charle's law

• 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 doesnt 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 B Both assertion (A) and reason (R) are correct but R doesnt give the correct explanation

PV = constant at constant temperature therefore, curve is rectangular hyperbola
and ideal gas obeys charles law but PV=constant is boyles law not charles law therefore, assertion is true reason is true but reason is not correct explanation of assertion
option(B) is correct
