How many times will the root mean square velocity of nitrogen molecules change if the gas temperature
May 1, 2021 | education
| How many times will the root mean square velocity of nitrogen molecules change if the gas temperature has increased 4 times?
In fact, this task will not be so difficult if you figure it out.
Let’s write the formula for the mean square velocity:
V1sq. = √ * (3 * R * T1 / M)
The second one will have T2, this is the only difference.
We decide further, in the end we will get 2 <V1sq.>
And then we are already entering the home stretch.
<V₂kv> / <V₁kv> = 2 <V₁kv> / <V₁kv>
In the end of such calculations, the answer will be the number 2.
This means that with an increase in the gas temperature by 4 times, the quadratic velocity, in turn, will increase by 2 times. This is the whole task.
