A closed vessel holds gas at 27°C. If the gas temperature is raised to 300°C, how does the resulting pressure change___________________?
Show answer Hide answer
Answer: A. Doubled
Explanation
For a closed rigid vessel, heating a gas increases pressure proportionally to absolute temperature (P2 = P1 * T2/T1). Converting temperatures: T1 = 300 K, T2 = 573 K, so the pressure change cannot be simply doubled without calculating the exact ratio.
