I would fill an ice cube tray and put it in the freezer (lower the temperature).

You change liquid water into ice by removing energy from the liquid water. You might do that by exposing it to something at a temperature below freezing. You could actually get some ice by spraying it through a nozzle into near vacuum. As the water sprayed through, a lot of energy from the liquid water would be used to vaporize some of the water - potentially dropping whatever liquid was left into ice.
A second way would be to put it under very high pressure. While at lower pressures, increasing pressure will cause ice to melt (which is one of the reasons ice skates work), when you get above about 200 MPa, increasing the pressure will solidify the liquid water. Of course when you get above the critical temperature you are really solidifying a supercritical fluid, not a liquid.
The energy required to change ice to liquid water is known as the heat of fusion. For ice to water, the heat of fusion is 334 J/g. Therefore, to change 24.7 g of ice to liquid water, the energy required would be 24.7 g * 334 J/g = 8259.8 J.
Physical change is a change in the appearance of something but the object retains the same chemical compounds such as ice is still H20 because it's made of water. Three examples would be: freezing water - liquid becomes solid; melting ice - solid becomes liquid; or evaporation - liquid becomes gas.
When ice melts, the particles do not change into a liquid; rather, the solid ice transforms into liquid water. The molecules in the ice gain enough energy to break their fixed positions and move more freely as a liquid.
Melting ice is an example of a physical change. It changes from solid ice to liquid water without altering its chemical composition.
No. Ice is less dense than water. Because ice is less dense it displaces less water and floats. Water is most dense at 4o C. any change in temperature, either up or down, lowers the density.
In the case of water (liquid) you would freeze it into ice (solid).
The energy required to change ice to liquid water is known as the heat of fusion. For ice to water, the heat of fusion is 334 J/g. Therefore, to change 24.7 g of ice to liquid water, the energy required would be 24.7 g * 334 J/g = 8259.8 J.
The water in ice has a larger volume that water in its liquid form. That is why Ice floats. Ice is less dense than liquid water.
How do you change ice to water? You melt it.
physical change because it is melting and it would be the same mass as it waas as a chunk of ice
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.
No, it is a physical change
Transformatiom from liquid water to solid water (ice).
It is a Physical Change. Melting it does not change what components/elements are found in snow. It is just a phase change from solid to liquid.
Freeze the liquid (put into freezer).
A glass of ice water is an example of a physical change, where water changes from a liquid to a solid state as it freezes. This change is reversible, as the ice can melt back into water.
If your're asking about the change of state, the answer would be Freezing. If you're asking about the state of ice, it would be solid.
