Energy is..
• The capacity to perform work• Kinetic Energy: actually doing work• Heat: energy associated with
movement of molecules• Potential Energy: capacity to perform
work
Thermodynamics
• Study of energy transformation• 1st law: conservation of matter• 2nd law: energy conversions reduce
the order of the universe (aka: increase disorder [entropy]).
Chemical Reactions
• Endergonic: requires a net input of energy.
Chemical Reactions
• Exergonic: a reaction that releases energy.
