Question

300ml of oxygen gas at _ 10°c are heated to 10°c. what is the new volume if pressure remains constant?

Answer 1

Answer:- 322.8 mL.

Solution:-  Charles law states, "At constant pressure, the volume of the gas is directly proportional to the kelvin temperature."

The equation used is:

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

subscripts 1 stands for initial values and subscript 2 stands for final values.

From given info, $V_1$ = 300 mL

$T_1$ = -10 + 273 = 263 K

$T_2$ = 10 + 273 = 283 K

$V_2$ = ?

Let's plug in the values in the equation:

$\frac{300mL}{263K}=\frac{V_2}{283K}$

$V_2=\frac{300mL*283K}{263K}$

$V_2$ = 322.8 mL

So, the new volume of the gas is 322.8 mL.

Answer 2

322.8 ml is the right answer.
