Question

20 ml of hydrogen gas at -13 degrees is heated to 117 degree C at constant pressure. Find new volume of hydrogen.

Answer 1

Answer:-

Given:

Initial Volume $\sf(V_1)$ = 20 ml

Initial Temperature $\sf(T_1)$ = - 13° + 273.15° K = 260.15° K.

Final Temperature $\sf(T_2)$ = 117° + 273.15

= 390.15° K

We know that,

Charley's law of gases states that at constant pressure the Volume of a gas is directly proportional to its absolute temperature.

→ V = kT (k is constant)

→ V/T = k

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

$\sf \: → \frac{20}{260.15} = \frac{ V_{2} }{390.15} \\ \\ \sf → V_{2} = \frac{390.15 \times 20}{260.15} \\ \\ → \sf \large V_{2} = 30 \: ml \: (approx.)$

Hence, the final Volume of the Hydrogen will be 30 ml.
