Question

Which of the following statements is not correct?

• A. At constant volume, the pressure of a contain amount of gas increases with increasing temperature
• B. At constant temperature, the pressure of a certain amount of gas increases with increasing volume
• C. At constant pressure, the volume of a certain amount of gas increases with increasing volume
• D. In dealing with gas laws, the most convenient scale of temperature to use is the kelvin temperature scale

Hint:

Remember, Boyle's Law states that pressure and volume are inversely related when temperature is held constant.

Answer 1

The Correct Option is B

At constant temperature, the pressure of a gas decreases as the volume increases, as described by Boyle's Law (P$\propto$1/V).
The other statements are correct: increasing temperature increases the pressure at constant volume, increasing volume increases the volume at constant pressure, and the Kelvin scale is preferred in gas law calculations as it avoids negative temperatures.
