Is it physical or chemical when ice melts?
When ice melts, it undergoes a physical change, not a chemical change. The molecules in the ice are still the same water molecules, but they are transitioning from a solid state to a liquid state.
Is sugar crystallizing a physical or chemical change?
Sugar crystallizing is a physical change because it involves rearranging the molecules of the sugar without changing their chemical composition.
Is snowflakes melting a chemical change?
Melting snowflakes is a physical change, not a chemical change. The water molecules in the snowflake remain the same chemical composition before and after melting, they just change from a solid to a liquid state.
Are physical and chemical change different?
Physical change does not produce a new substance. Chemical change produces a new substanceIn a chemical change the atoms/molecules are chemically joined together so they are very hard to separate. were as they are easyer to separate in a physical change
When Sugar dissolves in hot water a physical or chemical change?
When sugar dissolves in hot water, it is a physical change. This is because the sugar molecules are simply mixing with the water molecules but are not undergoing a chemical reaction to form new substances.
Is the breaking down of molecules a chemical or physical change?
It is a chemical change.
What happens in a chemical change but not in a physical?
Molecules permanently change. In a physical change the effects are reversible.
When ice melts is it a physical change or a chemical change?
It is a physical change. There is no chemical reaction whatsoever.
Is it physical or chemical when ice melts?
When ice melts, it undergoes a physical change, not a chemical change. The molecules in the ice are still the same water molecules, but they are transitioning from a solid state to a liquid state.
Is sugar crystallizing a physical or chemical change?
Sugar crystallizing is a physical change because it involves rearranging the molecules of the sugar without changing their chemical composition.
IS bees creating wax from sugar a physical or chemical change?
The process of bees creating wax from sugar is a physical change. It involves the physical transformation of the sugar molecules into wax molecules without any change in the chemical composition of the substances.
Is melting lard a chemical change?
No, it is a physical change because the chemical composition of the fat molecules are not changing.
Is a paper cut a chemical change?
No, it is a physical change, the paper's molecules are not changing.
Is dissolving NaCl in h2o a chemical change?
Dissolving NaCl in water is a physical change, not a chemical change. The NaCl molecules remain the same chemically, but the arrangement of the particles changes as they interact with water molecules.
What would be a rule deciding whether a change is chemical or physical?
- A physical change is a change of phase or dimensions. - A chemical change is a change of the chemical structure, new molecules are formed, the initial molecule is transformed.
Is Alcohol vaporizing physical change or chemical change?
Alcohol vaporizing is a physical change because it does not involve a change in the chemical composition of the alcohol molecules. It is simply a phase change from liquid to gas.
In physical change can matter change its shape?
If by matter you mean molecules / atoms then no. Physical change is when the look / shape of something is changed but not its chemical structure, chemical change is when the molecules that make up the object n question are changed.
