Question

Внаслідок нагрівання тиск газу в закритій посудині збільшився в 4 рази. У скільки разів змінилася середня квадратичная швидкість?

Answer 1

P=(1/3)*n*mo*v²
Увеличится в 2 раза

Answer 2

Calculation of Change in Average Quadratic Speed

When the pressure of a gas in a closed container increases by 4 times due to heating, the average quadratic speed of the gas changes. To calculate the change in the average quadratic speed, we can use the following formula:

Change in average quadratic speed = √(new pressure/old pressure)

Given that the pressure of the gas increased by 4 times, the new pressure is 4 times the old pressure.

Using the formula, the change in the average quadratic speed can be calculated as follows:

Change in average quadratic speed = √(4/1) = 2

Therefore, the average quadratic speed of the gas would change by a factor of 2.
