The Ruby fluorescence scale measures this quantity in a device by exciting electrons within its transparent chamber. Post-perovskite is a phase with high values of this quantity in a type of magnesium silicate. In 2023, a paper claiming to have observed superconductivity at 294 Kelvin in nitrogen-doped lutetium hydride in an environment where this quantity is high (15[1]-5[1])was retracted (15[1]-5[1])due to allegations of faking data (15[1])and self-plagiarism by its primary author, Rangas Dias. D-DIA (-5[1])and (*) diamond (10[1])anvil cells can be used (10[1])to subject materials (10[1])to high values of this quantity. (10[1])Enthalpy (10[1]-5[1])is defined as internal (10[1])energy plus (10[1])volume (10[1])times this (-5[1])quantity. This quantity is proportional to temperature over (10[3])volume (10[2])according to the ideal gas (10[1])law. Constant (10[1])in isobaric processes, (10[1])for 10 points, (10[1])name this quantity with SI unit Pascal, defined as force per area. (10[1])■END■ (10[2])
