16 de may. de 2024 · Boiling occurs when bubbles form within a liquid, marking a change from a substance’s liquid or solid phase into a gas. The normal boiling point is the temperature at which the liquid’s vapour pressure equals the standard sea level atmospheric pressure (760 mm [29.92 inches] of mercury).
Hace 3 días · Melting point: 0.00 °C (32.00 °F; 273.15 K) Boiling point: 99.98 °C (211.96 °F; 373.13 K) Solubility: Poorly soluble in haloalkanes, aliphatic and aromatic hydrocarbons, ethers. Improved solubility in carboxylates, alcohols, ketones, amines.
23 de may. de 2024 · Up to 99.63 °C (the boiling point of water at 0.1 MPa), at this pressure water exists as a liquid. Above that, it exists as water vapor. Note that the boiling point of 100.0 °C is at a pressure of 0.101325 MPa (1 atm ), which is the average atmospheric pressure.
17 de may. de 2024 · Mercury is silvery white, slowly tarnishes in moist air, and freezes into a soft solid like tin or lead at −38.83 °C (−37.89 °F). It boils at 356.62 °C (673.91 °F). It alloys with copper, tin, and zinc to form amalgams, or liquid alloys. An amalgam with silver is used as a filling in dentistry.

Hace 3 días · Hydrogen peroxide and water form a eutectic mixture, exhibiting freezing-point depression; pure water has a melting point of 0 °C and pure hydrogen peroxide of −0.43 °C. The boiling point of the same mixtures is also depressed in relation with the mean of both boiling points (125.1 °C).
Hace 5 días · It is a strong acid formed by dissolving the diatomic molecule hydrogen bromide (HBr) in water. "Constant boiling" hydrobromic acid is an aqueous solution that distills at 124.3 °C (255.7 °F) and contains 47.6% HBr by mass, which is 8.77 mol/L. Hydrobromic acid is one of the strongest mineral acids known.
