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

Nata [24]

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:

$P\cdot V = n \cdot R_{u}\cdot T$ (1)

Where:

$P$ - Pressure, measured in atmospheres.

$V$ - Volumen, measured in liters.

$n$ - Molar amount, measured in moles.

$T$ - Temperature, measured in Kelvin.

$R_{u}$ - 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:

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

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

$V_{2} = \left(\frac{T_{2}}{T_{1}}\right)\cdot V_{1}$

$V_{2} = \left(\frac{310.15\,K}{290.15\,K} \right)\cdot (8.5\,L)$

$V_{2} = 9.086\,L$

The new volume of the gas is 9.086 liters.

The primary gas in a volcano is: water vapor carbon dioxide sulfur dioxide nitrogen

Snezhnost [94]

Answer:

Water vapor

Explanation:

The magma consist of dissolved gases when these gases produce the force the volcanic eruption take place. The volcanic gases comes out and their volume is increased tremendously. The gases present in volcano are listed below:

The volcanic gases consist of water vapors, carbon dioxide and sulfur.

These three re the primary gases but the water is present in higher amount.

The percentage of water is 60%.

The carbon dioxide present in 10-40%.

Other gases present in valcano are nitrogen, argon, helium, neon methane and hydrogen.
