When a substance freezes, its physical state changes from liquid to solid, but its chemical composition remains the same. For example, water freezes into ice, and both have the same molecular structure (H2O). However, the arrangement of molecules changes, affecting properties like density and rigidity. Thus, while the form changes, the underlying chemical identity does not.
What else can I help you with?
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.
Is it a physical change when water in an ice cube tray freezes?
Yes, freezing of water in an ice cube tray is a physical change. It involves a change in state from liquid to solid without altering the chemical composition of water molecules.
When icicles form at the edge of a roof is it a physical or chemical change?
The formation of icicles at the edge of a roof is a physical change. It occurs when water freezes due to a drop in temperature, without any change in the chemical composition of the water molecules.
Does a physical change mean that something has matured or grown up?
A physical change doesn't involve the molecule composition of a substance.
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.
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.
Does ice undergo a chemical change when it freezes?
No, ice does not undergo a chemical change when it freezes. Freezing is a physical change that causes water molecules to slow down and come closer together, forming a solid structure with the same chemical composition as liquid water.
Is freezing point physical property a physical change a chemical property or a chemical change?
The freezing point is a physical property because it describes a characteristic of a substance (temperature at which it freezes) without changing the chemical composition of the substance. When a substance freezes, it undergoes a physical change from a liquid to a solid, not a chemical change.
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.
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.
Is it a physical change when water in an ice cube tray freezes?
Yes, freezing of water in an ice cube tray is a physical change. It involves a change in state from liquid to solid without altering the chemical composition of water molecules.
When icicles form at the edge of a roof is it a physical or chemical change?
The formation of icicles at the edge of a roof is a physical change. It occurs when water freezes due to a drop in temperature, without any change in the chemical composition of the water molecules.
Does a physical change mean that something has matured or grown up?
A physical change doesn't involve the molecule composition of a substance.
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.
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.
