Question

the particles within a substance are in constant motion. the particles in which of these substances have the lowest amount of kinetic energy?○ the wax of a candle at room temperature○ the water in a glass of ice water○ the steam from a cup of coffee○ the ice cube in a glass of tea

Explanation:

Kinetic energy of particles is directly related to temperature: lower temperature means lower average kinetic energy. The ice cube in iced tea is at the lowest temperature (0°C or below) compared to the other options: candle wax is at room temperature (~20-25°C), liquid water in ice water is at 0°C (but the ice itself is at a lower or equal temperature with more restricted particle motion), and steam from coffee is at a high temperature (100°C). Solid particles have the least motion and lowest kinetic energy among the states here.

Answer:

○ the ice cube in a glass of tea
