True or false every chemical or physical change in matter includes a change in energy?
True. Every chemical or physical change in matter involves a change in energy. Energy is either absorbed or released during these processes, leading to a change in the internal energy of the system. This principle is known as the first law of thermodynamics, which states that energy cannot be created or destroyed, only transferred or converted from one form to another.
What else can I help you with?
Is production of heat or light physical or chemical change?
i think it would be physical because it is still energy.
In a candle explain both changes using the big idea of energy?
When a candle is burnt a physical AND chemical change takes place. Its a physical change when the wax is being melted because the chemical structure has not change, meaning it cannot be a chemical change. Its also a chemical change because you are burning the string. When you burn something the chemical structure DOES change, meaning it is a chemical change.
Compare and contrast chemical change and physical change?
physical change is reversable while chemicle change is not and they both change because of some kind of energy that's all i can think of srry.
What occurs when energy is added or taken away?
When energy is added,solid will melt into liquid or liquid will change into gas. (When energy is added it gains heat).When energy is removed, the liquid will turn into solid or the gas will turn into liquid. (When energy is removed the heat will lose).
Is the melting of ice a physical change or a chemical change?
The melting of ice is a physical change, a change from the solid phase to a liquid phase by adding heat energy. The water can be refrozen into ice again, because it is the same chemical compound, H2O.Melting does not change the chemical elements in the ice (water), only their molecular form.Frozen water turns to liquid water. It is still water, so melting would be a physical change.
Is energy change a chemical or physical change?
Conduction of energy is a physical change.
Is energy a part of a physical or chemical change?
energy is part of a physical change
When energy is added or removed is a physical change or chemical change?
Physical
Is flash cameras flashing a chemical or physical change?
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.
Is a conductor of energy a physical or chemical change?
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.
Sunlight produced into stored energy physical or chemical change?
chemical change
When energy is added or removed physical or chemical change?
Physical
Is photosynthesis is chemical or physical change?
ChemicalCO2 is reduced into glucose. Water is oxidized into Oxygen.Also energy transformation occurs. Light energy transforms into chemical energy
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 is the energy in a chemical or physical change that is available to do useful work?
Free energy
What is the differences between a physical and chemical change in a candle?
The physical change will keep the atoms the same not moving but the chemical change will make it move around with energy.
Is energy transfer involved in every physical and chemical change?
No
