Energy: Forms, Transformation, Transfer, and Conservation
Item RG172002: The temperature of the surrounding environment increases during rusting because some chemical energy is converted into thermal energy during the chemical reaction.
Iron that is exposed to air will generally begin to rust. Rusting is a chemical reaction that occurs when iron atoms react with oxygen in the air. The reaction causes the temperature of the air to increase. Why would the temperature of the surrounding environment increase?
- Because new energy is made in the form of thermal energy when the chemical reaction occurs
- Because the energy that is stored inside the iron is released in the form of thermal energy when it is exposed to the oxygen in the air
- Because some chemical energy is converted into thermal energy during the chemical reaction
- Because some thermal energy of the air is used to start the chemical reaction

- PS1.B Some chemical reactions release energy, others store energy.
PS3.A Temperature is a measure of the average kinetic energy of particles of matter. The relationship between the temperature and the total energy of a system depends on the types, states, and amounts of matter present.
