energy notes
what is exothermic reaction?
what is energy?
the capacity to move, do work, change matter and produce heat
What is Thermochemistry?
the study of energy changes that happen during chemical reactions and changes in state
What is an endothermic reaction?
heat is absorbed from the surroundings because the reaction products are at a higher energy level than the reactants
what is potential energy?
the energy stored within the system
What is chemical potential energy?
Before the movement
What would be an example of potential energy
A stretched rubber band
What is kinetic energy?
the energy of an objects motion
What is Mechanical Potential Energy?
Before the object moves
When the rubber band is released and has motion it has
Kinetic Energy
What is chemical potential energy?
The energy that is stored in chemical bonds
What do plants transform light energy into biomass?
Photosynthesis
What are other forms of energy?
Radiation, x-rays, and electromagnetic
Activation energy, is the minimum energy colliding particles must have in order to react.
Continues burial, the increasing heat, and pressure will covert into?
Bituminous and then anthracite coal
