When you have a cup of boiling hot water next to a cup with ice cold water how does the movement of the water molecules change in each case?

Equilibrium of temperature. The water is trying to reach the same temperature as the environment it sits in. a cup of hot water has a higher temperature than the room so therefore begins to cool. a cup of cold water has a lower temperature than the room and therefore begins to heat up. both reach equilibrium when at the same temperature as the room

In the cup of boiling water, the water molecules have higher kinetic energy and move faster, leading to more chaotic movement. In the cup of ice-cold water, the water molecules have lower kinetic energy and move more slowly, resulting in a more orderly and structured movement.

Why is boiling water a physical change?
Boiling water is a physical change because it doesn't change the chemical composition of the water molecules. The water molecules simply gain enough energy to break away from their liquid state and become a gas, without any new substances being formed.
What occurs when heat is transferred into an object through motion or movement an example would be boiling water?
When heat is transferred into an object through movement, such as boiling water, it is known as convection. In this process, heat is transferred through the bulk movement of molecules within a fluid. As the water heats up, the hotter molecules rise to the top, transferring heat from the bottom of the pot to the top.
When water is boiling does it change from liquid to gas?
Yes, water changes from a liquid to a gas when it is boiling. At the boiling point, the molecules of water have enough energy to overcome the intermolecular forces holding them together as a liquid, allowing them to escape into the air as water vapor.
How is boiling water an example of a physical change?
Boiling water is a physical change because it involves a state change from liquid to gas without altering the chemical composition of the water molecules. The water molecules only change their arrangement and kinetic energy as they transition from liquid to gas, making it a physical change.
What energy transfer is boiling water?
heat

Why boiling water a physical change?
Physical change because the water molecules stay unchanged during boiling, also the germination phase helps this be proved correct=)

Is movement a chemical change?
No, That would be a physical change....A chemical change would be for like example: Water Evaporting, Water Boiling, Water Freezing...etc

Is boiling water a chemical or physical process?
Water boiling is a physical change and not a chemical reaction. In a physical reaction there is no new substance formed as is the case with chemical reactions. In boiling water there is no new substance produced.
Do the bubbles in a pot of boiling water for noodles indicate chemical change?
No, the bubbles in boiling water for noodles do not indicate a chemical change. The bubbles are formed due to the physical process of water reaching its boiling point and turning into steam bubbles. This is a physical change, as only the state of the water molecules is changing, not their chemical composition.
How does the movement of water molecules change when heat energy is added?
When heat is added to water, the water will change into water vapor because of how hot it gets. We tend to see the water boiling in this process, or when you see the bubbles in your mom's pot in the kitchen when she cooks spaghetti. When heat is taken away from the water, it will turn into a solid form, or freeze into ice.
When water is boiling does it change from liquid to gas?
Yes, water changes from a liquid to a gas when it is boiling. At the boiling point, the molecules of water have enough energy to overcome the intermolecular forces holding them together as a liquid, allowing them to escape into the air as water vapor.
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.
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.
Does boiling point affect the polarity of water?
No, boiling does not affect the polarity of water. What it does is create enough energy for the water molecules to separate from one another. But the water molecules are still polar.
