Yes, it's a physical change. Water is changing from liquid to gas. It is not a chemical change.
Yes because it is still the same substances just in different forms
Yes, it is a physical process.
Boiling is a physical change.
Boiling is a physical change.
It is a physical change.
The bubbles themselves are physical. What caused them might have been a physical change or a chemical change; it's impossible to say without more information.
This involves a change of state of the water. Before, during, and after the boiling, it remains water. So, since the substance doesn't change its character, the boiling of water is a physical change.
No, it is a physical change, like boiling, melting and freezing
No. That is a physical change of the liquid water turning to gas (steam)
Boiling is a physical change.
Boiling is a physical change.
Boiling is a physical change.
When water boils, it is a physical change.
It is a physical change.
Physical ... it's only a state change. Cool it and it reverts to its old condition.
It is NOT a chemical reaction. Boiling is a physical reaction. When heat is applied to water in a pot, the hydrogen and oxygen molecules begin to get excited; they bounce around everywhere. The heat traps the oxygen molecules in bubbles, which go to the sides of the pot (following the path of least resistance). These bubbles then come to the surface, releasing oxygen and steam. Boiling is simply a phase change from a liquid to a gas.
