Yes, very fast.
The rate of diffusion is inversely proportional to the square root of the molecular mass of the gas. Since the unknown gas diffuses 0.25 times as fast as helium, it means the square root of the molecular mass of the unknown gas is 4 times that of helium, thus the molecular mass of the unknown gas is 16 times that of helium, which is approximately 64 g/mol.
The abbreviation for gas helium is He.
If it is already a gas, it does not need to evaporate.
If you are a gas with two protons in your nucleus, you are helium. Helium is a noble gas known for being lightweight and non-reactive.
Helium is a colorless, odorless, tasteless and non-toxic gas at room temperature. It exists as a monatomic noble gas and is therefore inert and unreactive. It belongs to group 0 of the Periodic Table of Elements.
