An energy transformation from chemical to electrical to light energy is that a flashlight uses a battery to operate and the correct option is option B.
What is transformation of energy?An energy transformation is the change of energy from one form to another.
Energy transformations occur everywhere every second of the day. There are many different forms of energy such as electrical, thermal, nuclear, mechanical, electromagnetic, sound, and chemical.
The Law of Conservation of Energy states that energy can neither be created nor destroyed.
Therefore, An energy transformation from chemical to electrical to light energy is that a flashlight uses a battery to operate and the correct option is option B.

Does seeing a gas produced always mean a chemical reaction is occurring? Explain.
Answer:
Seeing a gas produced not always means a chemical reaction is occurring.
Explanation:
The following clues for an occurrence of a chemical reaction:
Color: The color of the solution changes when mixed with another solution or on the addition of a solid to a solution.Temperature: Rise or fall in temperature of the substance formedPrecipitation: Formation of solid substance that is precipitateGas evolution: Bubbles or gas formation. Evolution of gas or fumes from the solution.Odor: The smell of the reacting mixture initially differs from the smell of the productsYes, gas formation is one of the clues of the occurrence of a chemical reaction but it is not completely true.
This is because the evolution of gas also occurs when a substance undergoes a physical change.Water vapors on boiling water, sublimation of dry ice giving carbon dioxide gas.So, from this, we can conclude that seeing a gas produced not always means a chemical reaction is occurring.

What are the forms of light energy in solar radiation and the colors in white light?
(it has to be atleast 2 sentences)
Answer:
Light is a kind of energy called electromagnetic radiation. There are many different forms of electromagnetic radiation, such as radio waves, microwaves, ultraviolet rays, and X-rays. Each form is characterized by a different wavelength. For example, radio waves can be several miles long, while gamma rays are smaller than atoms. The light that we see — visible light — falls somewhere in the middle of this "electromagnetic spectrum.
Plsss help!! What would happen to a cup of hot coffee left untouched for 10 minutes. Include in your response temperature, molecules, and kinetic energy.
Answer:
The overall temperature of the coffee would decrease because the coffee would transfer its thermal energy into the surrounding air. The molecules would slow down in movement because when the coffee was hot, they were moving around faster. Subsequently, the kinetic energy of those molecules would also decrease
Explanation:
Answer:
the temperature would become cooler
