Question

V versus T curves, at constant pressure $ {{P}_{1}} $ and $ {{P}_{2}} $ for an ideal gas are shown in figure. Which statement is correct?

• A. $ {{P}_{1}}<{{P}_{2}} $
• B. $ {{P}_{1}}>{{P}_{2}} $
• C. $ {{P}_{1}}={{P}_{2}} $
• D. all of the above are correct

Answer 1

Answer: (A)

From Boyles law $ P\propto \frac{1}{V} $ (at constant T)
at a constant temperature $ {{T}_{1}} $ , we can see, that Volume corresponding pressure $ {{P}_{1}} $ > volume corresponding to $ {{P}_{2}} $ $ \therefore $ $ {{P}_{1}}<{{P}_{2}} $
