- Why do we still need to know about the Rankine temperature scale?
The Rankine scale ( ˈræŋkɪn ) is an absolute scale of thermodynamic temperature named after the Glasgow University engineer and physicist William John Macquorn Rankine, who proposed it in 1859 (The Kelvin scale was first proposed in 1848 ) It may be used in engineering systems where heat computations are done using degrees Fahrenheit
- physical chemistry - What is the difference between temperature and . . .
My course book says that kelvin is the unit of thermodynamic temperature, then what is the difference between temperature and thermodynamic temperature
- Dealing with different units (psi) in ideal gas equation
Strictly speaking, you don't even need to know what psi is Just apply the ideal gas law and return your answer in the same units
- Why is the volume of one mole of gas 22. 4 or 22. 7 dm3?
PV = nRT - sure, R is the universal gas constant, but primarily is a conversion from temperature units (T) to energy units (J) And, yes, the value of R can be measured using a variety of near-ideal gases and varying P, V, n, and or T as desired I'm not sure where the constant value you are struggling with comes in here
- evaporating DMSO Ethanol - Chemistry Stack Exchange
I'm preparing to do a thiolclick reaction and to get a homogenous phase I found it's best to use DMSO ethanol as solvent for the -ene and thiol reagents I need the ethanol specifically for hole-
- inorganic chemistry - Thermal Decomposition of Sulfur Hexafluoride . . .
Also, as a side note, SF6 reacts vigorously with Lithium metal (used to power the United States Navy's Mark 50 torpedo closed Rankine-cycle propulsion system per this source)
- What happens to pressure when a liquid goes supercritical?
Interesting that twice the pressure means half again the velocity in firearms, and twice the temperature seems to equal about half again the efficiency in Rankine-cycle power plants
- May I treat units (e. g. joules, grams, etc. ) in equations as variables?
You not only can, but also must treat symbols for units by the ordinary rules of algebra, since unit symbols are mathematical entities and not abbreviations The value of a quantity is expressed as the product of a number and a unit That number is called the numerical value of the quantity expressed in this unit This relation may be expressed in the form
