Find the velocity of nitrogen molecules at 418K.
| February 17, 2021 | education
The root mean square velocity of nitrogen molecules can be calculated using the formula:
V = √ (3k * T / m0), where k is the Boltzmann constant (k = 1.38 * 10-23 J / K), T is the absolute temperature (T = 418 K), m0 is the mass of the nitrogen molecule (m0 = 4.65 * 10-26 kg).
Let’s calculate the root mean square velocity of nitrogen molecules:
V = √ (3k * T / m0) = √ (3 * 1.38 * 10-23 * 418 / 4.65 * 10-26 kg) = 610 m / s.
Answer: The speed of nitrogen molecules is 610 m / s.
