WebSep 3, 2024 · If you know the total number of grams or moles of material, you can use the Δ Hfus or the Δ Hvap to determine the total heat being transferred for melting or solidification using these expressions: (12.5.1) heat = n × Δ H f u s. where n is the number of moles and Δ H f u s is expressed in energy/mole or. (12.5.2) heat = m × Δ H f u s. At low temperatures and at pressures up to around 400 GPa, hydrogen forms a series of solid phases formed from discrete H2 molecules. Phase I occurs at low temperatures and pressures, and consists of a hexagonal close-packed array of freely rotating H2 molecules. Upon increasing the pressure at low temperature, a transition to Phase II occurs at up to 110 GPa. Phase II is a broken-symmetry structure in which the H2 molecules are no longer able to rotate freely. If the p… cubechain
