Is helium gas matter
WebAug 21, 2024 · Helium is the second least reactive element and noble gas (after neon). Its low atomic mass, thermal conductivity, specific heat, and sound speed are greatest after hydrogen. Due to the small size of helium atoms, the diffusion rate through solids is three times greater than that of air and 65% greater than that of hydrogen. WebThe gas is in equilibrium, so it must appear the same in any direction, and the average velocities are therefore the same in all directions—i.e., vx2 = vy2 = vz2; thus v2 = 3 vz2. When the value (1/3) v2 is substituted for vz2 in the expression for pressure, the following equation is …
