# Will identical raindrops fall more rapidly in $$5{\rm{^\circ C}}$$air or $$25{\rm{^\circ C}}$$air, neglecting any differences in air density? Explain your answer.

The identical raindrops fall more rapidly.

See the step by step solution

## Step 1: Speed

The rate at which the location of an object changes in any direction. The ratio of distance traveled to the time it took to travel that distance is known as speed.

## Step 2: Explanation

The property of viscosity decreases with the increase in temperature. The rise in viscosity applies more resistance to the flow of water.

## Step 3: Conclusion

The raindrops gain more energy at higher temperatures, and stars fall more rapidly. The energy of this movement is enough to overcome the cohesive forces that attract the liquid molecules together. The viscosity of air and the raindrops is more at a higher temperature $$25{\rm{^\circ C}}$$.

Thus, the raindrops fall more rapidly $$25{\rm{^\circ C}}$$.
