What happens to particles as they approach the temperature shown?
A. They lose kinetic energy
B. They pick up speed.
C. They gain kinetic energy.
D. They heat up
SUB

With an increase in temperature, the particles move faster as they gain kinetic energy, resulting in increased collision rates and an increased rate of diffusion. ... With an increase in temperature, the particles gain kinetic energy and vibrate faster and more strongly.

Explanation:

answers: to make sure that all of the broken pieces of tablet were added to the water, to allow for fair comparison of all three trials, with different particle sizes to avoid experimental error
