Exercise Physiology Exam #2 Review

What is the First Law of Thermodynamics?

• Tendency of potential energy to convert to kinetic energy of motion with lower capacity for work.

• Any physical or chemical process that releases energy to its surroundings.​

• Energy cannot be created or destroyed, but only transformed from one state to another without being depleted.

• Chemical processes store or absorb energy.​
