Original: The total reaction is thus 2 H2 + O2 -> 2 H2O Examples of Physical Coefficients Coefficient of Thermal Expansion (thermodynamics) (dimensionless) - Relates the change in temperature to the change in a material's dimensions.
Simplified: Examples of Physical Coefficients Coefficient of Thermal Expansion (thermodynamics) (dimensionless) - Relates the change in temperature to the change in a material's dimensions.
