Different elements and molecules expand more or less rapidly and create different crystal structures.
The melting of ice to form water is a physical change. It involves a change in state from solid to liquid, but the chemical composition of the substance remains the same.
Putting ice in a soda to make it cold is a physical change. The ice melts into water, but it does not change the chemical composition of the soda itself.
An ice cube is solid, and contains little gas although there could be air bubbles inside the ice.
A melting ice cube is a physical change, because the ice cube is only changing size, shape, volume and state of matter.It's not a chemical change, because it's not changing into a different kind of matter with different properties.
The melting of an ice cube is considered both a physical change and a chemical change simply because a chemical change is something burning, so if the ice cube is cold and hot at the same time, it's both a physical change and a chemical change.
When a cube of ice melts to form water, it undergoes a physical change. This is because the substance remains water in both states, but changes from a solid form (ice) to a liquid form (water) due to a change in temperature.
It is a physical change.
Because melting sugar turns color to form caramel. i.e. it has changed and specifically it has undergone a CHEMICAL CHANGE (Or chemical reaction). When melting ice, no chemical reaction occurs, and so it is just a PHYSICAL CHANGE.
Its the change in a temperature. If its cold water might freeze and make an ice cube.
Its the change in a temperature. If its cold water might freeze and make an ice cube.
it melts fatser in soda because of the chemicals in soda + tastes nicer
use baking soda in the freezer
A physical change because the substance does not change. It is still H2O, but in a different form.
I think it will melt faster in soda, cause of the chemicals it has more than juice.
Heating an Ice cube with a hairdryer is ...Physical change
