Actually it's a math question. Can I cancel V from both side in step 3? thx!
The volumetric thermal expansion coefficient is a measure of the change in volume of a material for every degree of temperature change. It is represented by the symbol α (alpha) and is usually expressed in units of per degree Celsius (°C) or per degree Kelvin (K).
The volumetric thermal expansion coefficient can be calculated by dividing the change in volume (ΔV) of a material by the original volume (V0) and the change in temperature (ΔT). This can be represented by the formula α = ΔV/(V0ΔT).
A high value of volumetric thermal expansion coefficient indicates that a material will expand significantly when heated, while a low value indicates that the material will expand minimally. This can be important in applications where dimensional stability is crucial, such as in construction or engineering.
The volumetric thermal expansion coefficient takes into account the change in volume of a material, while the linear thermal expansion coefficient only considers the change in length. The volumetric coefficient is usually three times larger than the linear coefficient for isotropic materials.
The value of the volumetric thermal expansion coefficient can be affected by the type of material, its chemical composition, and its crystal structure. It can also vary with temperature, pressure, and the presence of impurities in the material.
