Thermal Expansion

• Units and Variables

• L - length, in meters
• T - temperature, in Kelvin
• α - coefficient of linear expansion, in ℃-1
• β - coefficient of volumetric expansion, in ℃-1
• $\mathrm{\Delta L}=\alpha {L}_{i}\mathrm{\Delta T}$
• $\beta =3\alpha$
• $\mathrm{\Delta V}=\beta {V}_{i}\mathrm{\Delta T}$
