Term
 Zeroth Law of Thermodynamics
Definition
 If A is in thermal equilibrium with B and B is in thermal equilibrium with C then A and C are also in thermal equilibrium
Term
 Linear Thermal Expansion Equation
Definition
 ΔL = αLΔT
Term
 Volumetric Thermal Expansion
Definition
 ΔV = βVΔT where β ≈ 3α
Term
 Heat Transfer via Conduction
Definition
 Direct transfer of energy via molecular collision
Term
 Heat Transfer via Convection
Definition
 The transfer of heat by the physical motion of a fluid
Term
Definition

Term
 1st Law of Thermodynamics
Definition
 [image] where Q is the heat transferred into the system and W is the work done by the system
Term
 Heat Capacity
Definition
 Q = mc∆T with Q being in units of joules,cal, or Cal (kcal)
Term

Definition
 q=mL
Term
 Thermodynamic Processes
Definition
 Isothermal: Q=W Adiabatic: ∆U=-W Isobaric: ∆U=Q-W Isochoric/Isovolumetric: ∆U=Q
Term
 2nd Law of Thermodynamics
Definition
 If 2 objects are in thermal contact but not thermal equilibrium then the object with higher temperature will give off heat to the other object until they reach thermal equilibrium - Energy is dispersed
Term
 Entropy Equation
Definition
 ∆S=Q/W
