Dissolved molecules and ions, or solutes, have thermal energy and are in constant random motion in solution. these dissolved substances will spontaneously demonstrate an increase in entropy in the absence of any outside influence. thermal energy in the form of kinetic energy thus allows for the movement of solutes or ions in solution, resulting in:

The ultracentrifuge is an important tool for separating and analyzing proteins. because of the enormous centripetal accelerations, the centrifuge must be carefully balanced, with each sample matched by a sample of identical mass on the opposite side. any difference in the masses of opposing samples creates a net force on the shaft of the rotor, potentially leading to a catastrophic failure of the apparatus. suppose a scientist makes a slight error in sample preparation and one sample has a mass 10 mg larger than the opposing sample. if the samples are 12 cm from the axis of the rotor and the ultracentrifuge spins at 70,000 rpm, what is the magnitude of the net force on the rotor due to the unbalanced samples? ( be thorough on your answer)
