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.
What else can I help you with?
Is steam superheated water?
No, steam is not superheated water. Steam is the gaseous form of water that is created when water is heated to its boiling point and vaporizes. Superheated water is water that has been heated beyond its boiling point and exists in a state where it is hotter than its boiling point.
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 an unusually high boiling point compared to other molecules of similar size due to the hydrogen bonds that form between the water molecules. The hydrogen bonds must be broken before water can boil.
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.
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?
The boiling point is the temperature at which a liquid will change into a gas. This happens when the molecules have enough energy to break the bonds holding them in close proximity. Since water molecules have a stronger attraction to each other than ethane molecules have for each other, water needs to be heated to a higher temperature to break these bonds.
When does water transform into a gas?
When heated to its boiling point.
Is steam superheated water?
No, steam is not superheated water. Steam is the gaseous form of water that is created when water is heated to its boiling point and vaporizes. Superheated water is water that has been heated beyond its boiling point and exists in a state where it is hotter than its boiling point.
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.
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.
