Thermal Expansion (Linear)
This interactive simulator explores Thermal Expansion in Thermodynamics. Linear ΔL = α L₀ ΔT; compare reference bar and heated/cooled length (schematic). Use the controls to change the scenario; watch the visualization and any graphs or readouts to connect the model with lectures, labs, and homework.
Who it's for: Suited to beginners and first exposure to the topic. Typical context: Thermodynamics.
Key terms
- thermal
- expansion
- thermal expansion
- thermodynamics
How it works
Most solids expand slightly when heated: fractional length change is proportional to temperature change, ΔL/L₀ = α ΔT, in the linear regime. Different materials have different coefficients α.
