Question

Scott made a model of the water cycle by filling a tub with water, covering the tub with clear plastic, and placing a heat lamp over the tub. After a few days, he observed water droplets collecting on the plastic wrap.What do the water droplets represent?

a. precipitation
b. condensation
c. transpiration
d. evaporation

Answer 1

b. condensation

Step-by-step explanation:

Condensation is a phenomenon which describes the physical change of matter from a gaseous form to a liquid form, when the matter in its gaseous state comes in contact with humid air. It is a kind of recycling process of water.

In the model of water cycle made by Scott, the water droplets observed that was collecting on the plastic wrap represents condensation. As water becomes vaporized in the tub, the gaseous form of the water comes in contact with humid air, which leads to condensation as seen in the collection of water droplets. The water vapor is converted back to the liquid form of water.

Answer 2

Answer: B

Step-by-step explanation:

When water is heated is changes from the liquid state of matter to the gas(vapour) state which is known as vaporization. While condensation is the change from the gas state to the liquid state, and it is the reverse of vaporization.

Condensation is the change in the state of water from its gaseous form into liquid water. When water is heated warm air rises (water vapor), when it cools and looses its capacity to hold water vapor, it forms changes back to the liquid state which is seen inform if water droplets on the plastic wrap.
