Fundamentals of Physics 4) Creating a Vacuum For centuries scientists have been trying to create lower and lower temperatures and pressures, initially by evacuating gas from containers with mechanical pumps. But today more refined technologies such as diffusion, ionisation, chemisorption … Continue reading →

  Fundamentals of Physics 5a)  Falsification of Kinetic Theory Diffusion The transport phenomena of the admixture of two different gases does not proceed as the theory predicts. This observation is confirmed in practice by the mixing of gases for commercial … Continue reading →

Fundamentals of Physics 5b) Falsification of Kinetic Theory Phase Changes The Ideal (Perfect) Gas Laws are another example and are an imperfect model of the reactions of gases to changes in pressure and temperature, and even then in a limited … Continue reading →
