Frequent question: What causes water to have a high boiling point quizlet?

What causes water’s high boiling point?

Water has an unusually high boiling point for a liquid. This is related to the intermolecular forces between water molecules; when a liquid has particularly large intermolecular forces, it will have a higher boiling point. Large intermolecular forces between molecules will favor the liquid state over the gaseous state.

Why does water have a high boiling point quizlet?

Water molecules contain two hydrogens attached to an electronegative oxygen; as a result, water can undergo hydrogen bonding, and it has an unusually high boiling point.

What type of interaction is responsible for water’s high boiling point?

Water molecules are stabilized by these hydrogen bonds, so breaking up (separating) the molecules is very hard. The hydrogen bonds account for water’s high boiling point and ability to absorb heat.

Why does H2O have the highest boiling point?

Water has a higher boiling point because the hydrogen bonds that form among water molecules are stronger than the Van der Waals interactions among methane molecules, thus more energy must be provided in order to break the hydrogen bonds and allow the water molecules to escape the liquid state.

What causes the high surface tension low vapor pressure and high boiling point of water quizlet?

The hydrogen bond creates a slightly positive side and a slightly negative side that allows the water to easily stick together. This is what creates waters high boiling point, low vapor pressure and high surface tension.

What factor causes high surface tension low vapor pressure and high boiling point of water?

Many unique and important properties of water—including its high surface tension, low vapor pressure, and high boiling point—result from hydrogen bonding. The structure of ice is a regular open framework of water molecules in a hexagonal arrangement. Water molecules are held together through hydrogen bonds.

What explains the very high melting and boiling point of water quizlet?

Hydrogen bonding, a particularly strong dipole-dipole force, causes a powerful attraction between water molecules, which results in a high boiling point.

Why does water has high boiling point than ethanol?

why does water have a higher boiling point than ethanol?

Where would water have the highest boiling point?

A liquid at high pressure has a higher boiling point than when that liquid is at atmospheric pressure. For example, water boils at 100 °C (212 °F) at sea level, but at 93.4 °C (200.1 °F) at 1,905 metres (6,250 ft) altitude. For a given pressure, different liquids will boil at different temperatures.

Why does water have a higher boiling point than methane?

Because oxygen is more electronegative than carbon, an O-H bond has a larger bond dipole than a C-H bond. Hence the force of attraction between two water molecules is greater than it is between two methane molecules. Water has the higher boiling point. … Therefore, methane has the higher boiling point.
