Types of Energy

100

A candle burning

Exothermic (releasing heat/energy)

100

What is the process where substances undergo a chemical change?



Chemical Reaction

100

Is this a type of energy?

Kinetic

Yes. It is the energy an object has due to it's motion.

200

photosynthesis

endothermic (absorbing heat/energy)

200

What is a reaction that releases heat?

Exothermic Reaction

200

Is this a type of energy?

Positional

No. Positional is not a type of energy.

300

Rust forming on metal

Exothermic (releasing heat/energy)

300

What is a reaction that absorbs heat?

Endothermic Reaction

300

Is this a type of energy?

Chemical

Yes. It is the energy stored in the bonds of chemical compounds that is released during reactions.

400

Baking bread

endothermic (absorbing heat/energy)

400

What is the substance made after a reaction?

Product

400

Is this a type of energy?

Mechanical

Yes. It is the sum of energy associated with the motion and position of an object.

500

Melting ice cubes

Endothermic (absorbing heat/energy)

500

Once a chemical reaction has happened, can you go back and "undo" it? 

No. The substances have changed to a new product and can't be changed back. For example, once you cook the dough and it becomes bread it cannot become dough again. 

500

Is this a type of energy?

Vehicle

No. Vehicle is a way of transportation not a type of energy.
