Charles' Law (Leaving Cert Chemistry): Flashcards

Jacques Charles

Volume directly proportional to absolute temperature

Kelvin

Volume increases

Volume decreases

$V \propto T$

$\frac{V_1}{T_1} = \frac{V_2}{T_2}$

Constant ($k$)

$K = \text{°C} + 273$

Particles gain energy, move faster, need more space

Straight line through origin

Moveable piston maintaining constant pressure

Heated air expands, becomes less dense, balloon rises

$-273\text{°C}$ or $0\text{ K}$

$\frac{V}{T}$ ratio
