A container of gas has a volume of 280 mL at a temperature of 22 Celsius if the pressure remains constant what is the volume 44

d1i1m1o1n [39]

Answer:

300.9mL

Explanation:

Given parameters:

V₁ = 280mL

T₁ = 22°C

T₂ = 44°C

Unknown:

V₂ = ?

Solution:

To solve this problem, we apply Charles's law;

it is mathematically expressed as;

$\frac{V_{1} }{T_{1} } = \frac{V_{2} }{T_{2} }$

We need to convert the temperature to kelvin;

T₁ = 22°C = 22 + 273 = 295K

T₂ = 44°C = 44 + 273 = 317K

Input the parameters and solve;

$\frac{280}{295}$ = $\frac{V_{2} }{317}$

V₂ x 295 = 280 x 317

V₂ = 300.9mL
