Endothermic or Exothermic
A candle burning
Exothermic (releasing heat/energy)
What is the process where substances undergo a chemical change?
Chemical Reaction
Is this a type of energy?
Kinetic
Yes. It is the energy an object has due to it's motion.
photosynthesis
endothermic (absorbing heat/energy)
What is a reaction that releases heat?
Exothermic Reaction
Is this a type of energy?
Positional
No. Positional is not a type of energy.
Rust forming on metal
Exothermic (releasing heat/energy)
What is a reaction that absorbs heat?
Endothermic Reaction
Is this a type of energy?
Chemical
Yes. It is the energy stored in the bonds of chemical compounds that is released during reactions.
Baking bread
endothermic (absorbing heat/energy)
What is the substance made after a reaction?
Product
Is this a type of energy?
Mechanical
Yes. It is the sum of energy associated with the motion and position of an object.
Melting ice cubes
Endothermic (absorbing heat/energy)
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.
Is this a type of energy?
Vehicle
No. Vehicle is a way of transportation not a type of energy.
