Question

Statement 1: A gas heated from ${10}^{o}C$ to ${100}^{o}C$ at constant pressure will increase in volume.
Statement 2: As Charle's Law states, if the pressure remains constant, the volume varies directly as the absolute temperature varies.

• A. Both Statement 1 and Statement 2 are correct and Statement 2 is the correct explanation of Statement 1.
• B. Both Statement 1 and Statement 2 are correct and Statement 2 is not the correct explanation of Statement 1.
• C. Statement 1 is correct but Statement 2 is not correct.
• D. Statement 1 is not correct but Statement 2 is correct.
• E. Both the Statement 1 and Statement 2 are not correct.

Answer 1

The correct option is A

Both Statement 1 and Statement 2 are correct and Statement 2 is the correct explanation of Statement 1.

Statement 1: A gas heated from ${10}^{o}C$ to ${100}^{o}C$ at constant pressure will
increase in volume.
Statement 2: As Charle's Law states, if the pressure remains constant, the
volume varies directly as the absolute temperature varies.
$PV=nRT$
$V\propto T$ ($n$ and $P$ constant)
Hence, Both Statement 1 and Statement 2 are correct and Statement 2 is the correct explanation of Statement 1.
