because the change either uses up enrgys, or the change absorbs energy in some way
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.
No
No, it is a physical change because there is no change in chemical composition of the substance that is condensing.
No, photosynthesis is a chemical change by which water and carbon dioxide are converted into oxygen and carbohydrates.There is an energy transformation. Light energy is converted to chemical energy
Okay now here goes in a physical change no chemical reaction takes place. in chemical change chemical reactions take place. A physical change is reversible but a chemical change is not.In a physical change no new substance is formed(A+B=B) in a chemical change new substances are formed(A+B=C)
no
Conduction of energy is a physical change.
energy is part of a physical change
Physical
When a rocket is launched, it undergoes both physical and chemical changes. The ignition of the rocket fuel is a chemical change, as it involves the breaking and forming of chemical bonds to release energy for propulsion. The physical changes include the motion of the rocket as it moves through the atmosphere and the transformation of potential energy into kinetic energy.
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.
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.
chemical change
Physical
ChemicalCO2 is reduced into glucose. Water is oxidized into Oxygen.Also energy transformation occurs. Light energy transforms into chemical energy
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.
