Density of helium at stp kg/m 3
WebHelium-3 boils at 3.19 K compared with helium-4 at 4.23 K, and its critical point is also lower at 3.35 K, compared with helium-4 at 5.2 K. Helium-3 has less than one-half of the density when it is at its boiling point: 59 gram per liter compared to the 125 gram per liter of helium-4—at a pressure of one atmosphere. WebFeb 3, 2024 · At sea level and at 15 degrees C, the density of air is 1.225 kg/m 3. This is the value of the ISA (International Standard Atmosphere).
