Sieverts law formula
Websolution have been found to obey Sievert s law, which reads: cH = K S P H 2 where ln K S = A + B T; B=-H R cH is the hydrogen content in atom ratio (concentration), PH 2 is the hydrogen equilibrium pressure, is the enthalpy of solution, R is the molar gas constant and A depends on the excess entropy of solution. The equation WebSo, the number of particles per square metre (which is actually what the detector counts!) is decreasing at a rate equal to the distance squared. This is what “inverse-square” means. At distance r we have 9 particles spread over 1 square metre; 9 ⁄ 1 = 9 particles per square metre. At distance 2 × r we have 9 particles spread out over 4 ...

WebGraham's law of effusion (also called Graham's law of diffusion) was formulated by Scottish physical chemist Thomas Graham in 1848. Graham found experimentally that the rate of effusion of a gas is inversely proportional to the square root of the molar mass of its particles. This formula is stated as: =, where: Rate 1 is the rate of effusion for the first gas.
