Why Water Is A Liquid At Room Temperature

Molecules like oxygen gas and nitrogen gas are gases at room temperature.

Why water is a liquid at room temperature.

It is an energy demanding or active process. At this temperature and ordinary pressure only two elements are liquids. Water s liquid state at room temperature and atmospheric pressure is probably attributable to hydrogen bonding. Water is a liquid at room temperature because the hydrogen bonds within its construction are weak.

The state of a molecule is determined by intermolecular forces such as dipole dipole. 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.

This is because of the tiny weak hydrogen bonds which in their billions hold water molecules together for small fractions of a second. Water moves from areas of high concentration to areas of low concentration. This is less than ammonia or dioxygen or dinitrogen a little more than methane but still less than ethane and propane. Water is a molecule of fairly negligible mass.

Elements that are liquid at 25 c. At room temperature anywhere from zero degree centigrade to 100 degrees centigrade water is found in a liquid state. Water molecules are constantly on the move. For science it s usually considered to be either 20 c or 25 c.

Room temperature is a loosely defined term that can mean anywhere from 20 c to 29 c.
