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.

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:

(1)

Where:

- Pressure, measured in atmospheres.

- Volumen, measured in liters.

- Molar amount, measured in moles.

- Temperature, measured in Kelvin.

- 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:

(2)

If we know that , and , then the new volume of the gas is:

The new volume of the gas is 9.086 liters.

the answer is d. 74.02
