It is true.
Energy is always involved.
No
The flash of a camera is a physical change, not a chemical change. A physical change is a change in the form of a substance without changing its chemical composition. In the case of a camera flash, electrical energy is converted into light energy, which is a physical process that does not alter the chemical makeup of the components involved.
Energy can be absorbed or released in a chemical or physical change, it is not destroyed or created. It simply assumes a different form.
Conduction of energy is a physical change.
energy is part of a physical change

Explode is a rapid physical change that occurs when substances release a large amount of energy in a short period of time, causing them to break apart or burst. It is not a chemical change because the substances involved do not undergo a change in their chemical composition during the process.
The conductor of energy is not a physical change. The conduction of energy happens due to a chemical bonding of specific metals. A conductor of energy produces a flow of electrical charges.
