Temperature Relationship between Kinetic Energy and Temperature Average translational kinetic energy of particles ――――𝐸k-trans and temperature 𝑇 enjoy a direct, one-to-one proportionality, as shown by the Ideal gas law ――――𝐸k-trans=12𝑚――𝑣2=32𝑘𝑇 where 𝑘 =1.381×10−23 JK−1 is Boltzmann’s constant. tidy | SemBr
