Cp for helium
WebAfter hydrogen, helium is the second most abundant element in the universe. It is present in all stars. It was, and is still being, formed from alpha-particle decay of radioactive elements in the Earth. Some of the helium formed escapes into the atmosphere, which contains about 5 parts per million by volume. WebHelium 5.22 2.26 +i:2 +i:3 P-V-2' data for the inert gases (1, 3-5, 10) are fairly meager. Of the existing helium data, a large portion is at values of TR and PR much higher than the range covered in this paper. This is due to the very low critical constants for helium. However, enough
