The phase change allows a substantial reduction in the mass of the material required for effective heat storage (the heat of fusion of sodium sulfate decahydrate is 82 kJ/mol or 252 kJ/kg [24]), with the further advantage of a consistency of temperature as long as sufficient material in the appropriate phase is available.

Mirabilite, also known as Glauber's salt, is a hydrous sodium sulfate mineral with the chemical formula Na 2 SO 4 ·10H 2 O. It is a vitreous, colorless to white monoclinic mineral that forms as an evaporite from sodium sulfate-bearing brines.
The molar mass of atoms of an element is given by the relative atomic mass of the element multiplied by the molar mass constant, M u ≈ 1.000 000 × 10 −3 kg/mol ≈ 1 g/mol. For normal samples from Earth with typical isotope composition, the atomic weight can be approximated by the standard atomic weight [ 2 ] or the conventional atomic weight.
Small business owners may not realize they are subject to a new reporting process mandated under the Corporate Transparency Act.
The molecular mass and relative molecular mass are distinct from but related to the molar mass. The molar mass is defined as the mass of a given substance divided by the amount of the substance, and is expressed in grams per mol (g/mol). That makes the molar mass an average of many particles or molecules (potentially containing different ...
I'd say it's a rare thing for King Charles to meet and greet non-royals, but that would be a total lie. The man is often out and about, shaking hands with and chatting with members of the public.
The polarizing Cybertruck hit 16,000 units sold in Q3, making it the No. 3 EV sold in the quarter, behind only Tesla’s Model Y and Model 3. Following Tesla are GM, which saw sales jump 60% in ...
