The primary bond that is broken when water is boiled is hydrogen bonds. There are other weaker intermolecular forces at work as well, but these are much weaker and not as significant. Once the hydrogen bonds are broken, the water molecules are not held as tightly together and can escape the liquid as gas.
When water is heated to boiling, hydrogen bonds between water molecules are broken. These hydrogen bonds are responsible for the structure and properties of water and hold water molecules together in a liquid state. As the temperature increases, the kinetic energy of water molecules overcomes the hydrogen bonds, causing them to break and water to evaporate into steam.

When water evaporates are intermolecular or intramolecular bonds broken?
When water evaporates, intermolecular bonds between water molecules are broken, not intramolecular bonds within the water molecule itself. The intermolecular bonds that are broken are hydrogen bonds between water molecules, allowing them to separate and become a gas.
How does boiling water dissolves borax and why?
When water is heated to its boiling point, the kinetic energy of the water molecules increases, allowing them to overcome the intermolecular forces holding the borax particles together. This increased kinetic energy helps break down the ionic bonds in borax, allowing it to dissolve in the water.
Water has an unusually high boiling point?
Water has a high boiling point because of its strong hydrogen bonding between molecules. This hydrogen bonding requires more energy to break the bonds between water molecules, leading to a higher boiling point compared to other molecules of similar size.
Do hydrogen bonds lower the boiling point of water?
No, hydrogen bonds actually increase the boiling point of water. Hydrogen bonds are strong intermolecular forces that require more energy to break, thereby increasing the boiling point of water compared to substances with weaker intermolecular forces.
Does boiling water contain any gasses?
Yes, boiling water can contain gases such as dissolved oxygen and carbon dioxide. When water is heated to its boiling point, these gases can be released as bubbles.
What bond is broken when starch is heated?
The hydrogen bonds in starch molecules are broken when starch is heated. This results in the gelatinization of starch, where the starch molecules absorb water, swell, and become thickened.
What is water when heated?
Water molecules are attracted to each other, resulting in the formation if weak chemical bonds, called hydrogen donds. When water is heated the heat energy disrupts the hydrogen bonds reulting in hydrogen bonds between water molecules to be broken.
Why does cooking a food change its hardness?
Heat can make and break chemical bonds. If something gets softer when heated (e.g. ice to water) the bonds are weakened or broken. If when heated it gets harder (e.g sauce that thickens) then the bonds are strengthened or created
What is heating water?
Water molecules are attracted to each other, resulting in the formation if weak chemical bonds, called hydrogen donds. When water is heated the heat energy disrupts the hydrogen bonds reulting in hydrogen bonds between water molecules to be broken.
What happened when water is heating?
Water molecules are attracted to each other, resulting in the formation if weak chemical bonds, called hydrogen donds. When water is heated the heat energy disrupts the hydrogen bonds reulting in hydrogen bonds between water molecules to be broken.
When water is heated rapidly changes into steam this process is called?
When water is heated rapidly and changes into steam, this process is called boiling.
Why the boiling point of water higher than the boiling point of Ethan?
Water has stronger hydrogen bonds between its molecules than ethane, resulting in a higher boiling point for water. These hydrogen bonds require more energy to break, hence water boils at a higher temperature than ethane.
When water evaporates are intermolecular or intramolecular bonds broken?
When water evaporates, intermolecular bonds between water molecules are broken, not intramolecular bonds within the water molecule itself. The intermolecular bonds that are broken are hydrogen bonds between water molecules, allowing them to separate and become a gas.
When does water transform into a gas?
When heated to its boiling point.
How does boiling water dissolves borax and why?
When water is heated to its boiling point, the kinetic energy of the water molecules increases, allowing them to overcome the intermolecular forces holding the borax particles together. This increased kinetic energy helps break down the ionic bonds in borax, allowing it to dissolve in the water.
Why is the boiling point 100?
Substance boil when their interparticular bonds are broken. For water the amount of energy needed to break the adhesive bonds between the water molecules at 1 atmosphere pressure. Boiling occurs at lower temperatures if the atmospheric pressure is lower ie on top of a mountain. Boiling is the temperature where the molecules have enough energy to spontaneously vaporise throughout the liquid.
Are hydrogen bonds easily broken?
Hydrogen bonds are weaker than covalent bonds but stronger than van der Waals forces. They are easily broken by external factors such as temperature, pH, and solvents. However, they play important roles in maintaining the structure and function of biological molecules.
