A colloid stays stable if attractive interaction energy is below what?
AThermal energy kT
BQuantum energy hv
CPotential energy mgh
DRest mass energy mc2
Answer & Solution
Correct answer: A. Thermal energy kT
If attraction is smaller than kT, thermal motion keeps particles apart, but a larger value lets them clump.
