NEVER • Attempt to mix gases in a cylinder. Although ABG monitoring has been replaced mainly by non-invasive monitoring, it is still helpful in confirming and calibrating non-invasive monitoring techniques. k. For complex particles with more than translational degrees of freedom, such a random thermal energy can be defined also for the other degrees of freedom (dof). The atoms still spin and the electrons still move but the entire atom doesn't go anywhere. ). Under suitable assumptions, the information required to compute averages for these systems can be reduced to the solution of an equation, the so-called Boltzmann equation. This internal random-motion energy is also called “thermal en-ergy”. 3 kPa (1 atm) of gas above the solutions. A gas is a collection of particles in constant, rapid, random motion (sometimes referred to as ‘Brownian’ motion). This process is the reverse of evaporation and it is called condensation.
