Thermal Expansion Quiz

The change in size (length, area, volume) of a material due to a change in temperature.

Change in length of an object due to temperature change.

ΔL = αL₀ΔT, where ΔL is change in length, α is coefficient of linear expansion, L₀ is initial length, and ΔT is temperature change.

Change in surface area of an object due to temperature change.

ΔA = βA₀ΔT. ΔA is change in surface area, β is coefficient of surface expansion, A₀ is initial surface area, and ΔT is temp change

Change in volume of an object due to temperature change.

ΔV = γV₀ΔT. ΔV is change in volume, γ is coefficient of volume expansion, V₀ is initial volume, and ΔT is temperature change.

β = 2α and γ = 3α. These equations relate the coefficients for linear, surface, and volume expansion.

A temperature scale where 0°C is the freezing point of water and 100°C is the boiling point of water.

An absolute temperature scale where 0K is absolute zero (no heat energy).

A temperature scale where 32°F is the freezing point of water and 212°F is the boiling point of water.
