You have a balloon filled with hydrogen gas which keeps it at a
constant pressure, regardless of its volume. The initial volume
of the gas is 736 mL at 15.0 °C. The gas is heated until its
volume is 2.28 L, what is its final temperature in degrees
celsius?

Respuesta :

The final temperature is 46.5°C.

Explanation:

As per the Charles law, the volume of a gas at constant pressure is directly proportional to the temperature which is measured in Kelvin.

So the equation for the Charles law is given as,

[tex]$\frac{V}{T} = constant[/tex]

[tex]$\frac{V1}{T1} = \frac{V2}{T2}[/tex]

Now we have to find T2 as,

[tex]$T2 = \frac{V2T1}{V1}[/tex]

V1 = 736 ml = 0.736 L

T1 = 15 ° C

V2 = 2.28 L

Now plugin the values as,

T2 = [tex]$\frac{2.28 \times 15}{0.736}[/tex]

    = 46.5°C

So as we see that as the volume increases, temperature also increased.
