The freezing point of water is 0 C (32 F).

The difference between a liquid and a solid is the space between the atoms.

To become more dense (a solid) the orbit of the electrons has to become less. This requires losing energy. As energy cannot be made or destroyed, it has to be transferred. This removal of energy is the removal of heat.

Why doesnt temperature change when transferring from ice too water?

The thermal energy required to change state is taken from the environment; which in this case is the melt water.

Is the melting of ice a physical change or a chemical change?

The melting of ice is a physical change, a change from the solid phase to a liquid phase by adding heat energy. The water can be refrozen into ice again, because it is the same chemical compound, H2O.Melting does not change the chemical elements in the ice (water), only their molecular form.Frozen water turns to liquid water. It is still water, so melting would be a physical change.

The temperature of a mixture of ice water remains at 0 degress C even though is applied only when the ice melts does the temperature rose this is because?

During the course of change of state heat energy given or taken from does not appear as a rise in temperature or fall in temperature of the substance; it is hidden in that substance and is called latent heat and is utilized to produce the change of state. Here mixture water and ice remains at zero degree Celsius, heat energy required to melt the ice is taken from water until it's temperature falls to zero degree.Thereafter the heat energy received is utilized by the ice until it is fully melted.During that time the temperature remains steady at zero degree celsius.When all the ice is converted into water the temperature gradually rises.

Examples of reversible physical change?

examples of physical change are ice,water,chocolate,liquid,

What is an exaple of physical change?

A type of change in which the form of matter is changed to another form is called a physical change. Thus the chemical change does not occur, but only a physical change occurs in it. Example: When ice melts into water When water is boiled, and it changes into water vapor.

What must be taken away from water for it ti change to ice?

only heat energy really; placing water in a cold environment (like the freezer) freezes it, creating ice.

When heat is taken away from water it changes from a liquid to what?

Water changes to a solid, ice, when heat is taken away from it. You can think of putting water into the freezer. Since the freezer is cold, heat flows out of the water making it become ice cubes.

What happens if energy is added or taken away from a glass of ice water?

That depends on how much energy, but simply:added, more ice melts to water - if enough is added all the ice will melt and the temperature risestaken away, more water freezes to ice - if enough is taken away all the water wii freeze and the temperature will dropAs long as there is both ice and water the temperature will hold constant.

Is melting ice cube physical change?

yes because its changing from one form to another form which is physical!!!

When a cube of ice melts to form a puddle of water is it a physical change?

Yes. No chemical change has taken place, only a physical change. It can be undone (liquid water can be re-frozen)

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.

Which processes of the water cycle show heat being added and which ones show heat beign removed?

How the water cycle and heat are related: Adding or subtracting heat makes the water cycle work. If heat is added to ice, it melts. If heat is added to water, it evaporates. Evaporation turns liquid water into a gas called water vapour. As water goes through its cycle, it can be a solid (ice), a liquid (water), or a gas (water vapour). Ice can change to become water or water vapour. Water can change to become ice or water vapour. Water vapour can change to become ice or water. If heat is taken away from water vapour, it condenses. Condensation turns water vapour into a liquid. If heat is taken away from liquid water, it freezes to become ice. The water cycle involves the sun heating the Earth's surface water and resulting in the surface water evaporating. The water vapour rises into the Earth's atmosphere. The water cools and condenses into liquid droplets. The droplets grow until they are heavy and fall to the earth as precipitation (which can be rain, freezing rain or snow).

How do wind water and ice change the land?

water and ice and wind change the mountains by erosion

When water boils away is it a chemical or physical change?

I think that's just a physical change, because the water in whatever state, liquid, ice or vapor, is H2O definitely correct!
