Liquid oxygen at 50 K is heated to 300 K at constant pressure of 1. Temperature Choose the actual unit of temperature: ☌ ☏ K °R Choose the actual pressure: 1 bara / 14.5 psia 10 bara / 145 psia 50 bara / 725 psia Specific weight is given as N/m 3 and lb f/ ft 3. The output density is given as kg/m 3, lb/ft 3, lb/gal(US liq) and sl/ft 3. The calculator below can be used to estimate the density and specific weight of gaseous oxygen at given temperature and pressure. Oxygen phase diagram Online Oxygen Density Calculator Tabulated values of oxygen density at given temperature and pressure (SI and Imperial units) as well as density units conversion are given below the figures. Where g = acceleration due to gravity, units typically and value on Earth usually given as 9.80665 or 32.17405 Specific weight, γ, has units typically or is defined by the ratio of the weight to the volume of a substance: The rate of heating is constant. Whenever you make an observation in the laboratory that just doesn't "feel" right, trust your instinct, pause, ensure safety, and more thoughtfully assess the situation before proceeding.Density, ρ, has units typically or, and is defined by the ratio of the mass to the volume of a substance: Click hereto get an answer to your question Liquid oxygen at 50 K is heated to 300 K at constant pressure of 1 atm. Carry out the experiment in a fume hood behind appropriate shielding, wear appropriate PPE for the situation, and alert your lab-mates what you are planning to do. Whenever you're going to be sealing something with the potential for evaporation/expansion, a quick Henry's Law calculation should be carried out to ensure that the system won't reach a critical pressure and rupture the container. When using LN2 cooling, never use an experimental set-up that contains air or oxygen. If there is an oxidizable material already in the flask (e.g., solvent and/or other organic material), the liquid oxygen may react rapidly even at the LN2 cold bath temperature. An empty vessel exposed to an oxygen headspace, most typically simply open to air, will condense/liquify the oxygen. In general, boiling is a phase change of a substance from the liquid to the gas phase.The boiling point of a substance is the temperature at which this phase change (boiling or vaporization) occurs. Use of LN2 always introduces an added layer of risk because it has a lower boiling point (-196 ☌) than oxygen (-183 ☌). Do not let ammonia gas go into the fume hood as it will oxidize anything in it (including the monitor for air flow). Make sure to have a trap to capture ammonia that did not condense. This is the case for many things, not just ammonia-we are too quick to reach for LN2 for many applications (freeze/pump/thaw degassing, for example). There's no need to use LN2 (-196 ☌) when a dry ice +acetone/IPA bath (-78 ☌) would suffice.
