Why Water Is A Liquid At Room Temperature

Water molecules are constantly on the move.

Why water is a liquid at room temperature.

Water s liquid state at room temperature and atmospheric pressure is probably attributable to hydrogen bonding. It is an energy demanding or active process. These weak bonds hold water molecules together for mere milliseconds which keeps water in a constantly liquid state at room temperature. 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 less than ammonia or dioxygen or dinitrogen a little more than methane but still less than ethane and propane. Because of hydrogen bonds we have lakes and streams. Water is a liquid at room temperature due to the presence of hydrogen bonds between water molecules.

For science it s usually considered to be either 20 c or 25 c. It occurs whenever solutions are separated by a semipermeable membrane. This is because of the tiny weak hydrogen bonds which in their billions hold water molecules together for small fractions of a second. Elements that are liquid at 25 c.

The state of a molecule is determined by intermolecular forces such as dipole dipole. At this temperature and ordinary pressure only two elements are liquids. Water is a molecule of fairly negligible mass. If they are moving fast enough they become a gas.

At room temperature anywhere from zero degree centigrade to 100 degrees centigrade water is found in a liquid state.
