What is the difference between giving off light and reflecting light?
Giving off is emitting it and reflecting light is reflecting it
Is temperature change a physical or chemical change?
Temperature is the perception we have of the vibrational energy of the molecules in any substance. The faster they vibrate, the hotter the object. So the answer is physical.
When energy is given off as heat the physical change is said to be?
Exothermic
Example of physical change in an object?
A physical change is a change which affects only the physical properties of an object, not its chemical properties. Examples include breaking glass, smoothing a rock with a sander, and freezing water. As long as a new substance is not created in a process, the process is a physical change.
What is the meaning of luminous materials?
Luminous means giving off light. Any material becomes luminous if sufficiently heated.
When a firecracker explodes giving off light and heat and breaking the wrapper into many pieces is that a physical change chemical change or both?

A substance is giving off heat light and smoke Most likely the type of change that is occurring is?
Fire
Is a firefly giving off light a chemical or physical change?
It's not a change at all. It is simply what the firefly does. But it is a result of a chemical change within the firefly. A chemical reaction involves a transfer of energy. In this case, the energy would go into creating light waves from the molecules in the firefly, causing it to glow.
Is a light bulb a chemical or physical change?
A light bulb is not a change in and of itself but the process by which it gives off light is physical. While an electric current causes a given component of the bulb to glow (it may be the filament of an incandescent bulb or the vapor in a fluorescent one), but that substance does not change its chemical identity.
5 examples of science?
Change in temperature, gaseous bubbles, giving off light, change in color, change in properties. These are chemical changes, but it is still five examples of science.
Is breaking off a branch of a tree a physical change?
Breaking off a branch of a tree is a physical change.
In a firework show the fireworks explode giving off heat and light is this a chemical change why?
It is a chemical change because the chemical composition is changed during this reaction.
