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

Why is boiling water a physical change?
Physical change because the water molecules stay unchanged during boiling, also the germination phase helps this be proved correct=)
How would particles change in evaporation?
Firstly, evaporation doesn't mean boiling, boiling is when the temperature reaches the boiling point. However, evaporation will occur in any temperature, and we can't see them. It occurs when there is exposure of water to air and water molecules change into vapor and these vapors rise up and form clouds.
What effect does the transfer of heat have on the particles of water?
The transfer of heat in the water and in other liquid takes place by the movement of Molecules from the source of heat to the other part of liquid.This results the Boiling in the liquid.
When water is boiling does it change from liquid to gas?
Correct, boiling water changes from liquid to gas.
Convection and radiation?
the process by which heat is transfered by the movement of molecules in liquids and gases is known as convection...eg-boiling of water

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
Why boiling water is physical changes?

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.
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.
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.
Can you freeze water at its boiling point?
No, the water's molecules are moving too fast at its boiling point to freeze.
Why does water change from a liquid to a gas in evaporation?
Evaporation is caused by the continuous Brownian movement of water molecules; several molecules gain sufficient energy to escape in the atmosphere.
When you boil water is it a chemical change or physical change?
It is a physical change, known as a phase transition (see related links below).There is no chemical change: the water molecules remain water molecules. They have simply acquired enough kinetic energy to escape the attraction of the molecules in the liquid and move (almost) freely.
What will happen to the water molecules when water boils?
It's actually a lot simpler than that. When liquid water boils, some of the water molecules in a liquid state become so energetic that they go into a gaseous state. They remain water molecules, completely unchanged in their internal composition. They just change how they relate to other molecules. The only "gas" that's released during boiling is water vapor. As such, you can reheat the same water a thousand times and you won't get any change in the boiling process (other than loss of the liquid as the water vapor wisps away). The water molecules in a liquid state will become water molecules in a gaseous state, and the process will be the same on the first, second, and thousandth time.
