Heat is a form of energy (the kinetic energy present in the vibrations of atoms or molecules). Radiant energy can be turned into heat energy. Potential energy can be turned into heat energy, nuclear energy can be turned into heat energy, electrical energy can be turned into heat energy, magnetic field energy can be turned into heat energy and chemical energy can be turned into heat energy. There is no such thing as "physical" energy (in terms of Physics). Also your use of the term "evolved" can not be applied to a changing in type of energy, the term refers to the genesis of living things.
Icy Hot is a physical reaction. When applied to the skin, it produces a sensation of heat or cold by irritating nerve endings, rather than undergoing a chemical reaction.
Adding hot water to pot noodles is a physical change. The hot water causes the noodles to absorb the water and soften, changing their physical state without altering their chemical composition.
No, it is a chemical change Iron turns green means it is oxidized to ferrous (Fe+2) state.
Filling a balloon with hot air is a physical change because the hot air is simply expanding and occupying more space within the balloon, without any change in its chemical composition.
Mixing coffee with hot water is a physical change because the individual substances (coffee and water) retain their chemical identities and only the physical state of the coffee changes, dissolving in the water. No new substances are formed.
CHEMICAL:)
Dissolving sugar in hot water is a chemical change.
Dissolution is a physical change.
Its physical because the chemical properities of it doesn't change.
hot cold

It is a physical change because the chemical composition of the glass does not change.
No, it is a chemical change Iron turns green means it is oxidized to ferrous (Fe+2) state.
no it is a chemical change
A decrease in temperature is a physical change, not chemical.
well when you burn somthing then it is a chemical change but the hot dog isn't a new substance and a physical change is when you break or cut somthing so i think it should be chemical because it is being burned
