As a result of heating, the gas pressure increased n = 4 times. how many times k has changed the mean square velocity?
| September 12, 2021 | education
To calculate the desired change in the mean square velocity, we will use the ratio: Vk / Vn = √ (3Pk / ρ) / √ (3Pn / ρ) = √ (Pk / Rn), whence we express: Vk = √ (Pk / Rn) * Vn = √ k * Vн.
Variables: k – pressure increase (k = 4 p).
Calculation: Vk = √k * Vn = √4 * Vn = 2Vn.
Answer: The root mean square speed has doubled.
