Physical change:
When a physical change happens, physical characteristics could be altered, but it is the same material that you started with, or you cannot get that material back.
When a physical change happens new materials are produced/ substances are different than they were before. Smells, foaming, light, and smoke are observed.
Chemical Change:
When a chemical change happens, chemical characteristics could be altered, but it is the same material that you started with, or you can get that material back.
When a chemical change happens new materials are produced/ substances are different than they were before. Smells, foaming, light, and smoke are observed.
Exothermic Reaction:
In an exothermic reaction, energy is absorbed from the surroundings. As a result, the temperature of the surrounding drops.
In an exothermic reaction, energy is released into the surrounding as heat. As a result, the temperature of the surrounding increases.
Endothermic reaction:
In an endothermic reaction, energy is absorbed from the surroundings. As a result, the temperature of the surrounding drops.
In an endothermic reaction reaction, energy is released into the surrounding as heat. As a result, the temperature of the surrounding increases.
