H2O2 Coefficient of Cubical Expansion
To calculate the specific volume (Vt2) at temperature t2, from known values of specific volume at some base temperature (Vt1) using a given set of coefficients of expansion (B). Where: B = Coefficient of cubical expansion.
Vt2 = Vt1[1 + B(t2 – t1)]

Notes:
- The expansion coefficient is greater than that of water.
- H2O2 solutions < 45 wt.% expand during freezing, while those > 65% contract
