Q
What are the assumptions made for an ideal gas?
A
- The gas contains a very large number of atoms or molecules moving in random directions with random speeds
- Atoms or molecules of the gas occupy a negligible volume compared with volume of the gas
- The collisions of atoms or molecules with each other and the container walls are perfectly elastic
- Time of collisions is negligible
- Electrostatic forces between atoms or molecules are negligible except during collisions

Q
What is mean square speed?
A
Average of the squared speeds of all the particles, so the root of its gives you the typical speed.
