Write 3 differences between chemical and physical change?
Chemical changes involve the formation of new substances with different chemical properties, while physical changes do not. Chemical changes typically involve the breaking and forming of chemical bonds, while physical changes involve changes in state, shape, or size of a substance. Chemical changes often involve a change in energy, such as the release or absorption of heat, while physical changes usually do not result in a significant energy change.
What changes food energy into chemical energy?
The mitochondria changes food energy to chemical energy.
Are the changes produced by electrolysis chemical or physical in nature?
The changes produced by electrolysis are chemical in nature. The process involves the conversion of electrical energy into chemical energy, resulting in the decomposition of compounds into their constituent elements or ions.
What are characteristics do all chemical changes have?
All chemical changes involve the formation of new substances with different properties. They typically involve changes in the arrangement of atoms and the breaking and forming of chemical bonds. Chemical changes are often irreversible and are accompanied by changes in energy.
Which involves more energy a chemical change or a phase change?
A chemical change typically involves more energy than a phase change because it involves breaking and forming chemical bonds, which requires more energy than changing the arrangement of molecules in a substance during a phase change. Additionally, chemical changes often involve a change in temperature as well.
Does a chemical change create a temperature change?
Almost all chemical changes release or take in energy, and thus do result in changes in temperature.
Is chemical energy related to chemical change?
Yes it is released/ absorbed during chemical changes.
What is chemical change and energy changes combustion?
Bust down
Is energy change only involved with chemical change?
Energy changes are possible also in other situations.
Why do reactions always involve a change in energy?
Chemical bonds always break in chemical reactions, causing changes in energy.
What does the chemical energy stored in the batteries change into when the flashlight turns on?
Chemical energy stored in a battery changes into electrical energy.... Not so complicated
In a chemical change energy does what?
In a chemical change, energy is either absorbed or released. This can result in changes in temperature, light production, or other forms of energy transfer during the reaction.
What are four forms of energy related to change in matter?
Four forms of energy related to change in matter are thermal (heat) energy, chemical energy, nuclear energy, and electrical energy. These forms of energy can cause physical or chemical changes in matter by providing the necessary energy for these changes to occur.
What changes chemical energy to energy?
The mitochondria changes food energy to chemical energy.
When does chemical energy change into nuclear energy?
Chemical energy does not change into nuclear energy. Chemical energy is associated with the bonds between atoms in molecules, whereas nuclear energy is associated with changes in the nucleus of an atom, such as nuclear fission or fusion.

What energy change takes place when a battery is in use?
A battery changes chemical energy into electric (electromagnetic) energy.
