Is water is heated and changed to steam a physical change or chemical change?
chemical
What does water turn into when it is heated?
Vapor, its chemical elements do not change.
If water if heated and changed into steam is this a chemical or physical change?
The change of water into steam is a physical change. This is because the molecules of water are simply being rearranged into a different state (liquid to gas) without undergoing any chemical reactions.
If you take borax and boiling water and make crystals is this a physical change or a chemical change?
It is a chemical change, because the borax reacts to the heated water.
Is adding water to heated copper sulfate crystals chemical or physical?
Adding water to heated copper sulfate crystals is a chemical change. When water is added to heated copper sulfate crystals, the copper sulfate undergoes a chemical reaction where it dissolves in the water to form a solution. This is a chemical change because the chemical composition of the copper sulfate is altered during the process.
When water gets heated what change may take place?
When water is heated a physical change may take place. The water may evaporate and become water vapor, but the chemical makeup of the water (H2O) will not change.
Is hot water an chemical or physical change?
Heating water to make it hot is a physical change, as the water's chemical composition remains the same. The change in temperature simply affects the kinetic energy of the water molecules, causing them to move faster and appear hot.
How can volume change if a substance undergoes a chemical change?
If a substance undergoes a chemical change, its properties change. For example, water, when heated turns into a gas which has a higher volume.
When water is heated and changed into o steam is that a chemical or physical change?
The change from water to steam is a physical change. It involves a change in the physical state of the substance without any alteration in its chemical composition. The water molecules are still the same, they are just being converted from a liquid to a gas state.
Is boiling a kettle a chemical change?
Boiling a kettle is a physical change because it is a change in state from liquid to gas without altering the chemical composition of the water. The water molecules are simply being heated to a point where they gain enough energy to overcome the intermolecular forces holding them together, turning into steam.
Is there evidence of a chemical reaction when bubbles form on heated water?
Bubbles forming on heated water are usually due to the process of water vaporization rather than a chemical reaction. When water is heated, the molecules gain energy and move faster, eventually reaching a point where they break free from the liquid surface and form bubbles of water vapor. This phase change is a physical process, not a chemical reaction.
Is salt being removed from water a chemical change?
No, it is not.
