Nitrogen was heated from 17°C to 37°C. The original volume of nitrogen was 8.5 L. Find the new volume in liters assuming P and n remain the same.

Answer:

The new volume of the gas is 9.086 liters.

Explanation:

Let suppose that nitrogen has a behavior of ideal gas, the equation of state for ideal gases is:

[tex]P\cdot V = n \cdot R_{u}\cdot T[/tex] (1)

Where:

[tex]P[/tex] - Pressure, measured in atmospheres.

[tex]V[/tex] - Volumen, measured in liters.

[tex]n[/tex] - Molar amount, measured in moles.

[tex]T[/tex] - Temperature, measured in Kelvin.

[tex]R_{u}[/tex] - Ideal gas constant, measured in atmosphere-liters per mole-Kelvin.

If pressure and molar amount of the gas remain constant, then we construct the following relationship:

[tex]\frac{T_{1}}{V_{1}} = \frac{T_{2}}{V_{2}}[/tex] (2)

If we know that [tex]T_{1} = 290.15\,K[/tex], [tex]P_{1} = 8.5\,L[/tex] and [tex]T_{2} = 310.15\,K[/tex], then the new volume of the gas is:

[tex]V_{2} = \left(\frac{T_{2}}{T_{1}}\right)\cdot V_{1}[/tex]

[tex]V_{2} = \left(\frac{310.15\,K}{290.15\,K} \right)\cdot (8.5\,L)[/tex]

[tex]V_{2} = 9.086\,L[/tex]

The new volume of the gas is 9.086 liters.
