Question

If a sample of gas occupies a volume of 6.80 L at 325°C, what will its volume be at

25.0°C if the pressure does not change?

Answer 1

3.4L

Step-by-step explanation:

Given parameters:

Initial Volume of gas = 6.8L

Initial temperature of gas = 325°C = 325 + 273 = 598K

Final temperature = 25°C = 25 + 273 = 298K

Unknown:

Final volume = ?

Solution:

To solve this problem, we apply the Charles's law. It can be expressed as;

`(V1)/(T1)` =
`(V2)/(T2)`

V and T are volume and temperature

1 and 2 are initial and final states

Now insert the parameters and solve;

`(6.8)/(598)` =
`(V2)/(298)`

2026.4 = 598V2

V2 = 3.4L
