1. 1.

   Which of the following statements correctly describes the relationship between the temperature of a substance and the motion of its particles?

   • A) As temperature increases, the average kinetic energy of the particles decreases, causing them to move more slowly.
   • B) Temperature measures the total potential energy stored in chemical bonds, which does not affect particle speed.
   • C) Temperature is a measure of the average kinetic energy of the particles, so higher temperatures correspond to faster particle motion.
   • D) Temperature is determined solely by the mass of individual particles, so heating causes the particles to gain mass.
