You heat a mug of water to make hot chocolate. Which statement best
describes the changes in the water?
A. The kinetic energy of the particles increases as the temperature
increases.
B. The potential energy of the particles increases as intermolecular
forces are overcome.
C. The potential energy of the particles increases as the temperature
increases.
D. The kinetic energy of the particles increases as intermolecular
forces are overcome.
As the particles are heated they begin to vibrate.This vibration causes them to bump into each other and hence results in kinetic energy. So as the temperature increases, the particles vibrate more and bump into each other more which would increase kinetic energy.
