Boiling is a physical change because the substance is changing from a liquid to a gas without changing its chemical composition.

Water boiling is the process where water reaches its boiling point (100 degrees Celsius or 212 degrees Fahrenheit) and transitions from a liquid to a gas. This transition is accompanied by the formation of bubbles as the water vaporizes.
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, the bubbles in boiling water for noodles do not indicate a chemical change. The bubbles are formed due to the physical process of water reaching its boiling point and turning into steam bubbles. This is a physical change, as only the state of the water molecules is changing, not their chemical composition.
No, it is a physical change, like boiling, melting and freezing

Boiling oil is a physical change because it involves a change in state from liquid to gas without altering the chemical composition of the oil.
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.
