Which of the following statements about the beakers of water shown in the image is true?

• The particles in Beaker B are moving much

  slower, so it has more thermal energy.

• The particles in Beaker B are moving much

  faster, so it has more thermal energy.

• Both beakers have the same amount of particles, so they have the same amount of thermal energy.

• The particles in Beaker B are moving much

  slower, so it has less thermal energy.

_______ measures the average kinetic energy of the particles in a substance, and a _______ measures the total kinetic energy of the particles in a substance.

• heat / thermal energy

• temperature / thermal energy

• thermal energy / temperature

• heat / temperature
