Question

Which object will have particles with the highest average kinetic energy?(1 point)
Responses

A. water at 37°C in a glass
B. a drop of water at 90°C
C. an iceberg at 0°C
D. water at 40°C in a swimming pool

Answer 1

The object that will have particles with the highest average kinetic energy is:

**B. a drop of water at 90°C**

The average kinetic energy of particles in a substance is directly related to its temperature. Since 90°C is higher than 37°C, 0°C, and 40°C, the particles in the drop of water at 90°C will have the highest average kinetic energy.
