The scientist performed the cathode ray experiment leading to the discovery of electrons was Thomson
1- The lighter the molecule, the higher the K value.
2- when K value: is the ability of a material to conduct heat.
and materials with low thermal conductivities don't easily allow heat energy to pass through.
3- The thermal conductivity should increase with decrease molecular weight.
So as the molecular weight decreases the K value be higher.
Answer:increase In kinetic energy of molecules
Explanation:increase in kinetic energy of molecules
