What else can I help you with?
Why does the kinetic energy of water molecules remain the same when it reaches the boiling point?
average kinetic energy of molecules is roughly equivilant to temperature. as water reaches boiling point the temperature stops increasing. Instead the energy your putting in makes a phase change from liquid to gas.
Can boiling water effectively kill cockroaches?
Yes, boiling water can effectively kill cockroaches by scalding them.
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.
Why is it recommended to put cut flowers in boiling water?
It is recommended to put cut flowers in boiling water to help them absorb water more easily and stay fresh longer. Boiling water helps to remove any blockages in the stems and allows the flowers to take in water more effectively, keeping them hydrated and vibrant.
What is the boiling point of carbonated water?
The boiling point of Carbonated water is 105°C because of the carbon dioxide gas it contains.
Is boiling water to make tea a reversible change or a chemical reaction?
it's a reversible change
How is the boiling of water and the cooling of water vapor reversible?
Because the water stays water, its only a phase change.
Is tea a reversible change or non-reversible change?
It is not a reversible change. During boiling some components are extracted with hot water from the crushed dried leaves. It is impossible to restore the original leaves.
Which of them is a reversible change coffee dissolving Water boinling Chocolate melting wood burning?
Coffee dissolving, water boiling and chocolate melting are reversible physical transformations whereas wood burning is a chemical combustive transformation.
Is boiling water to make steam a permanent change?
No, boiling water to make steam is a physical change, as it can be reversed by cooling the steam back into water. The water molecules remain the same substance throughout the process.
Is boiling water to make tea a chemical reaction or a reversible change?
Boiling water to make tea is a reversible physical change. When water boils, it changes from liquid to gas, but it can easily be reversed by cooling the gas back into liquid form. No new substances are formed during this process, indicating that it is a physical change, not a chemical reaction.
How is boiling water and water vapor a reversible reaction?
Boiling water and the formation of water vapor is a physical change that is reversible because the process can be reversed by cooling the vapor back into liquid water. When water is heated to its boiling point, it transforms from liquid to gas (water vapor). If the vapor is then cooled, it condenses back into liquid water, demonstrating that the original state can be restored. This interchangeability between liquid and vapor forms signifies a reversible reaction.
A keetle of water boiling to form steam reversible or irreversible?
The process of a kettle of water boiling to form steam is reversible, as it can be reversed by cooling the steam back into water. This transformation involves a change in state from liquid water to gaseous steam and is driven by the input of heat energy.
Is water boiling in a kettle a chemical or physical change?
Boiling water in a kettle is a physical change. This is because the change is reversible, and it involves a phase transition from liquid to gas without changing the chemical makeup of water molecules.
Is boiling water irreversible?
From a thermodynamics standpoint, it depends how the process is carried out. If the system (the water) and the surroundings remain close to equilibrium during the entire process then the water boils reversibly. So if the change in temperature is approximately zero throughout the process and the process takes an infinitely long amount of time to carry out you can reversibly boil water.If you were asking whether water vapor can turn back into liquid water, then yes the process of turning water into water vapor is reversible.
What is the difference between boiling water and decomposing water?
Boiling water is the process in which water reaches its boiling point and turns into vapor, while decomposing water involves breaking down water molecules (H2O) into its constituent elements, hydrogen and oxygen. Boiling water is a physical change, while decomposing water is a chemical change. Boiling water is reversible, while decomposing water is typically irreversible.
Can you consider a chemical change dissolving salt in a water?
no because it is reversible. If you dissolve out the water you are left with NaCl. A change that is reversible is a physical change.
