Cp for helium
WebFor a temperature change at constant volume, dV = 0 and, by definition of heat capacity, d ′ QV = CV dT. (31) The above equation then gives immediately (32) for the heat capacity at constant volume, showing that the change in internal energy at constant volume is due entirely to the heat absorbed. To find a corresponding expression for CP ... WebUses. Helium is used as a cooling medium for the Large Hadron Collider (LHC), and the superconducting magnets in MRI scanners and NMR spectrometers. It is also used to …
