yes it is because its all soarts of chemicals in the soap
For the most part it is a chemical change because the soap bonds with the grease chemically. But also the action of rubbing your hands can cause some of the grease to come off, just like when you wipe your hands off on a paper towel.
Yes, because the chemicals in the soap react with the heat in a chemical raction. When the heat attracts to the soap the soap will inflate and become bubbles.
There's no reason soap is made to clean with bubbles.

The formation of a precipitate is a chemical change.

Soap scum is a substance, not a change; but the formation of scum is a chemical process.
It's called iridescence, which is an optical phenomenon which occurs when the hue of a multi-layered and semi-transparent object such as soap bubbles appears to change due to the phase shifting of light within the soap bubbles as the angle from which the bubbles is viewed changes.

The bubbles of a soap has no colour compared to the soap because when the soap mixes with the water it looses its colour and the bubbles formed are colourless.
Becasue of chemical chain reactions.
No, the formation of soap scum is not a chemical change. Soap scum appears as the result of a physical change. Some of the soap and whatever has become incorporated into the soap and water dry. After the water is gone, the things left are from the soap and whatever mixed with the soap when it was "working" at cleaning.
When the soap gets wet it causes it to produce bubbles.
Bubbles are formed from soap when they are mixed with water and there is air. When air is present and water is mixed with soap, bubbles will definitely form.
There's no reason soap is made to clean with bubbles.
Soap molecules have non-polar and polar ends. When mixed with water, the soap dissolves, therefore having a physical change (but maintaining its chemical properties). The polar ends are in contact with water and consist of a salt, the non-polar ends are a long chain of hydrocarbons that do not mix with water.When soap molecules mix with water they form micelles, that consist of a bunch of molecules that in the center have the non-polar end (that traps dirt and other organic compounds) and in the exterior have the polar end in contact with water.
