Estimate pressure of air molecules at 273 K, if mean square speed is 500m²/s² and density of air is 6kg/m³:
- A
1 x 10³ Pa
- B
2.5 x 10² Pa
- C
1 x 10² Pa
- D
2.7 x 10³ Pa
We are going to be using the formula; Pressure= ⅓ x density x mean square speed.
The formula for measuring pressure of the gas is given under:
P=1/3xdx√2rms
Root mean square velocity is explained as under:
Remember the formula has square of root mean square velocity.
Now lets plug in all values in the formula
P=1/3 x 6 x 500
=1000 or 1x10³Pa
This option is incorrect.
