Is it a chemical change when water is boiled?
No, it is a physical change.
Boiled water for making pasta is it chemical or physical change?
Boiling is a physical change.
Is Boiling water is a chemical change?
No, it is a physical change because the water is the same but just boiled
Is boiled water a chemical change?
Boiling water is a physical change, not a chemical change. The water molecules remain the same chemical composition (H2O) even though they change state from a liquid to a gas. This change is reversible.
Is water being boiled a chemical change or physical change?
It is a physical change because the water only changes its state from liquid to gas.
When a kettle is boiled you can tell it is NOT chemical change because?
When a kettle is boiled, it is not a chemical change because the water molecules are simply changing state from liquid to gas due to the heat, without any change in their chemical composition. The process is reversible, as the water vapor can condense back into liquid water.
Is water boiled to make pasta a chemical or a physical Change?
Boiling water to make pasta is a physical change because the water undergoes a phase change from liquid to gas, but its chemical composition remains the same. The molecules in water are rearranged, but no new substances are formed during the boiling process.
Dissolving salt into water is it physical or chemical change?
This is a physical change. You can separate the salt and water by the physical process of distillation or evaporation where the water is boiled away and the salt is left behind.
When water is boiled in a pot it bubbles Is this the result of a chemical reaction Explain why or why not?
The bubbling of water when boiled is not the result of a chemical reaction. It is due to the conversion of liquid water to water vapor, which forms bubbles as it rises to the surface. This process is physical in nature, involving the phase change from liquid to gas.
Describe the physical and chemical changes that occur when a pot of water is boiled over a campfire?
The chemical changes are in the campfire- the wood combines with oxygen from the air, releases heat and carbon dioxide. The water does not have a chemical change, but does have a physical change- it changes from a liquid (water) to a gas (steam).
Is it a physical change chemical change when salt dissolves in water?
Physical
Is boliling water a chemical or physical change?
Boiling water is a physical change because it does not change the chemical composition of the water.
