Question

Charles' law is represented mathematically as :

• A. $V_t = KV_0 t$
• B. $V_t= \frac{KV_0}{t}$
• C. $V_t = V_0 \left( 1 + \frac{273}{t}\right)$
• D. $V_t = V_0\left( 1 + \frac{t}{273}\right)$

Answer 1

Answer: (D)

$V_t = V_0\left( 1 + \frac{t}{273}\right)$

Answer 2

Charles' law is represented mathematically as $V _{ t }= V _{0}\left(1+\frac{ t }{273}\right)$
It can also be represented as $V _{ t }= V _{0}\left(\frac{ T }{ T _{0}}\right)$ or $V \propto T$
At constant pressure, volume of the given mass of the gas is directly proportional to absolute temperature.
