Question

Observe the diagram below. Which container of water has molecules with the greatest average kinetic energy?

The options are
36°C, □container a.
42°C, □container b.
68°C, □container c.
82°C, □container d.

Answer 1

D, 82 C. This is because when the heat increases he motion of the particles increases, increasing the total kinetic energy. Therefore, the hotter an object the more kinetic energy.
