Why is water (H 2 O)a liquid at room temperature whereas methane (CH 4 )is a gas?

Water forms hydrogen bonds due to the presence of hydrogen atoms bonded to a highly electronegative oxygen atom, which gives it a higher boiling point and makes it a liquid at room temperature. Methane, on the other hand, can only form weaker dispersion forces, which is why it is a gas at room temperature.
