Since the volume is the same, the specific gas that will take three times longer to evaporate than helium has a molecular mass of 36 u, and \(\frac{3}{1}\) equals the root square of \(\frac{Mw_2}{4}\).
The mass, calculated, is 36 u.

If the monochromatic source in Young's double slit experiment is replaced by white light,
1. There will be a central dark fringe surrounded by a few coloured fringes
2. There will be a central bright white fringe surrounded by a few coloured fringes
3. All bright fringes will be of equal width
4. Interference pattern will disappear
The matter is made up of very tiny particles and these particles are so small that we cannot see them with naked eyes.
The three states of matter are as follows:
