Why Water Is A Liquid At Room Temperature

Water is a liquid at room temperature because the hydrogen bonds within its construction are weak.

Why water is a liquid at room temperature.

Because of the hydrogen bonding between water molecules water is a liquid at room temperature. Molecules like oxygen gas and nitrogen gas are gases at room temperature. Room temperature is a loosely defined term that can mean anywhere from 20 c to 29 c. At room temperature anywhere from zero degree centigrade to 100 degrees centigrade water is found in a liquid state.

For science it s usually considered to be either 20 c or 25 c. Water is a liquid at room temperature due to the presence of hydrogen bonds between water molecules. Because of hydrogen bonds we have lakes and streams. It is an energy demanding or active process.

If they are moving fast enough they become a gas. These weak bonds hold water molecules together for mere milliseconds which keeps water in a constantly liquid state at room temperature. Water molecules are constantly on the move. Water moves from areas of high concentration to areas of low concentration.

The state of a molecule is determined by intermolecular forces such as dipole dipole. This is because of the tiny weak hydrogen bonds which in their billions hold water molecules together for small fractions of a second. At this temperature and ordinary pressure only two elements are liquids. It occurs whenever solutions are separated by a semipermeable membrane.

This is less than ammonia or dioxygen or dinitrogen a little more than methane but still less than ethane and propane.
