Thermal equilibrium
When objects do not exchange energy between one another.
Zeroth law of thermodynamics
When objects A and B are separately in thermal equilibrium with C, then A and B are in thermal equilibrium with each other.
Proportion between length and temperature of an object.
ΔL=αL_iΔT
Proportion between volume and temperature of an object.
ΔV=βV_iΔT
Proportionality constant for length and volume. Units.
α = average coefficient for a material's linear expansion. °C^(-1) β = same, but for volume. °C^(-1)
Relationship between α and β.
β=3α
