because hydrogen was very small and also because of avogadros principle
If you have studied hard in life science you should know this but the real answer is that yes the nebular hypothesis was made by helium and hydrogen..
Hydrogen's physical state at room temperature is a gas.
Hydrogen's temperature is mainly 13.8033 kelvins.
According to the nebular hypothesis, our solar system formed from a huge rotating cloud made mostly of hydrogen and helium gas, with trace amounts of heavier elements. The cloud, or nebula, slowly collapsed under its own gravity, leading to the formation of the sun and the planets.
Hydrogen is a gas at room temperature.
At room temperature, hydrogen is in the gaseous phase.
