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.
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).
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.
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 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
Burning gasoline in a car's engine a physical change or a chemical change?
Chemical but the energy released has physical consequences.
Is it a chemical or physical change when energy in food molecules is transferred into molecules of ATP?
Chemical change.
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
Compare the total amount of energy before and after physical and chemical changes?
Physical Change-- Same amount of energy, but in different form Chemical Change-- Different amount of energy, and in a different form
What is the energy in a chemical or physical change that is available to do useful work?
Free energy
Is carving wax a chemical or physical change?
Physical change. It is still wax, and can be uncarved by being melted and recast. Chemical changes cannot be undone without applying energy.
