What will happen to the molecules when it freezes?
When a molecule freezes, the kinetic energy of that molecule decreases, and the molecules do not move as fast. It is chemically unaltered, but on the phase has changed, making it a physical change.
Does a physical change mean that something has matured or grown up?
A physical change doesn't involve the molecule composition of a substance.
Does the composition of the ice change when it melts?
The composition of ice is H2O, and once it melts to water, its composition is ... H2O! So, no, the composition does not change.
What is a psyhical reaction?
A physical reaction, or change, is one that can be observed without changing the chemical composition of the substance. Boiling is a physical change because the substance that is boiling does not change its chemical composition. For example, water is still H2O whether it is boiling or not boiling.
What happens to the composition of matter when matter undergoes a chemical change?
A chemical change involve a change of composition.
Why is freezing a physical property?
Freezing is a physical change because the substance that freezes does not change its chemical composition.
Is it physical or chemical when water freezes at 0 degree celsius?
When liquid water freezes to form ice, the chemical composition of water does not change. It will be H2O whether it is in liquid state or solid state. So it is a physical change and not a chemical change.

Describe how the motion and arrangements of particles change as a substance freezes?
The particles get so attracted to each other making them form into a solid
Why is freezing a physical change?
Freezing is a physical change because although change obviously takes place, what something is made of does not change when it freezes. Liquid water and ice are the same substance for example.
Is melting point a physical or chemical?
Physical--- melting something doesn't change its chemical composition.
Is iron rusting physical or a chemical property?
Chemical. Something else is created as a result, and the composition does change, making it a chemical change.
Why do the flame change colours according to the different element in flame test?
it has something to do with the chemical composition of the elements.
What si physical weathering?
Physical weathering is the breaking down of something which does not change a substance's composition itself
Does the composition of the ice change when it melts?

What is the difference between a phisical change and a chemical change?
A physical change is one you can see. It changes the size, shape, or color of something. A chemical change is one that changes the composition of something. Basically, when a substance is changed into a different substance.
