Why Water Is A Liquid At Room Temperature

Water s liquid state at room temperature and atmospheric pressure is probably attributable to hydrogen bonding.

Why water is a liquid at room temperature.

Because of the hydrogen bonding between water molecules water is a liquid at room temperature. The state of a molecule is determined by intermolecular forces such as dipole dipole. At room temperature anywhere from zero degree centigrade to 100 degrees centigrade water is found in a liquid state. This is less than ammonia or dioxygen or dinitrogen a little more than methane but still less than ethane and propane.

Water is a liquid at room temperature because the hydrogen bonds within its construction are weak. Water moves from areas of high concentration to areas of low concentration. It is an energy demanding or active process. Room temperature is a loosely defined term that can mean anywhere from 20 c to 29 c.

Molecules like oxygen gas and nitrogen gas are gases at room temperature. This is because of the tiny weak hydrogen bonds which in their billions hold water molecules together for small fractions of a second. Water molecules are constantly on the move. If they are moving fast enough they become a gas.

At this temperature and ordinary pressure only two elements are liquids. Because of hydrogen bonds we have lakes and streams. It occurs whenever solutions are separated by a semipermeable membrane. Water is a liquid at room temperature due to the presence of hydrogen bonds between water molecules.

Water is a molecule of fairly negligible mass.
