Is chemicals in a battery reacting to the power of a flashlight a physical or chemical change?
The reaction of chemicals in a battery to power a flashlight is a chemical change. This is because the chemicals in the battery undergo a chemical reaction to produce electricity, which powers the flashlight.
Discharging of a flashlight battery a physical change?
Discharging of a flashlight battery is a chemical change because it involves the chemical reaction of the battery components producing electricity through oxidation and reduction reactions. This process leads to a change in the chemical composition of the battery materials, unlike physical changes that only affect the physical state or appearance of a substance without altering its chemical composition.
Does a flashlight change from chemical energy to light energy?
Yes, a flashlight changes stored chemical energy into light energy when the battery powers the light bulb. The chemical energy in the battery is converted into electrical energy, which then powers the light bulb's filament to produce light.
Is discharging battery a physical change?
Discharging a battery involves a chemical change where the stored chemical energy is converted into electrical energy. This is not considered a physical change because the composition of the materials inside the battery changes during the discharging process.
What element is negative electrode in the common flashlight battery?
The negative electrode in a common flashlight battery is typically made of zinc.
When a flashlight battery corrodes and leaks when stored for a long time is this a chemical or physical change?
This is a chemical change. The corrosion and leaking of the battery involve the breaking and rearranging of chemical bonds within the battery, leading to the formation of new substances (such as corrosion products).
Is chemicals in a battery reacting to the power of a flashlight a physical or chemical change?
The reaction of chemicals in a battery to power a flashlight is a chemical change. This is because the chemicals in the battery undergo a chemical reaction to produce electricity, which powers the flashlight.
What brands of batteries are chemical batteries?
Chemical battery: handset lithium battery electric car battery flashlight dry Physical battery: calculators the solar cells

This process leads to a change in the chemical composition of the battery materials, unlike physical changes that only affect the physical state or appearance of a substance without altering its chemical composition.
When does chemical change happen on a flashlight to produce electricity?
It happens when you turn on the flashlight and a circuit is created through the batteries, through the light filament, back down the outside of the batteries to the end of the batteries, etc. Switching off the flashlight breaks the circuit, curtails the chemical reaction in the batteries, and the light goes out.
Is a dry cell used in a flashlight an example of mechanical energy?
No, a dry cell used in a flashlight is an example of chemical energy, not mechanical energy. The chemical reactions in the battery produce electrical energy that powers the flashlight.
Does a flashlight change from chemical energy to light energy?
Yes, a flashlight changes stored chemical energy into light energy when the battery powers the light bulb. The chemical energy in the battery is converted into electrical energy, which then powers the light bulb's filament to produce light.
Is charging a battery a physical or a chemical change?
Chemical.
How does energy change in a flashlight?
Energy in a flashlight changes from stored chemical energy in the battery to electrical energy when the battery powers the light bulb, which then converts electrical energy into light and heat energy.
What is the sequence of energy transformation occurs after a battery operated flashlight is turned in?
When a battery-operated flashlight is turned on, the chemical energy stored in the battery is converted into electrical energy, which powers the light bulb, producing light energy and heat energy.
Which came first the battery or the flashlight?
The battery ... without that it can't be a flashlight.
Is a battery creating electricity a physical or chemical reaction?
chemical
