Frost skips the liquid state, and immediately goes to the solid state of ice.
substances
Thermal energy cause thermal decomposition of a compound; the bonds between atoms are weakened.
Starting substances are called reactants in a chemical reaction. Reactants are the substances that are present at the beginning of a chemical reaction and undergo transformation into products.
activation energy
Reactants are the substances that undergo chemical changes in a reaction. They are the starting materials that are transformed into products during a chemical reaction.
Substances that undergo chemical change are called reactants.
deposition means collection of some substances. Example: the deposition of copper killed him.
All substances have physical changes.
Substances that change from gas to solid undergo a process called deposition. Examples include water vapor turning into snowflakes, carbon dioxide subliming into dry ice, and iodine subliming into solid crystals.
When an acid and a base undergo neutralization, the two substances formed are water and a salt.
CHEMISTRY.
The substances that can react with oxygen and give out heat and light i.e., undergo combustion are called combustible substances.

substances
When one substance or combination of substances undergo change to become another substance or substances
chemical changes
Reactants are the substances present at the beginning of a chemical reaction that undergo a chemical change. In an equation, reactants are written on the left side of the arrow, indicating the substances that will undergo the reaction to form the products.
