In our experiment that will compare how long it will take for 100 ml distilled water to evaporate from a from a 5" diameter container. This will be the control group. For the experiment group, we will use 100 ml of distilled water and dissolve 10 grams of table salt in the water. We will use the same diameter dish for both samples so the same amount of water surface is exposed to the air.
What would a good hypothesis be?
When the salt water was almost evaporated, the higher concentration of salt might have slowed the evaporation process by blocking the air from the moisture.
We think that a pure water sample will dissolve faster than a salt water solution because salt adds more mass to equal quantities of liquids.
It took a total of 31hrs. 15 min. to evaporate the pure water and 32hrs. 10 min for the salt water.
We poured the water into each 5" dish and set the containers on a table. We noted the time: 8:00 a.m. Saturday.

Answer:The answer is C: How long does it take distilled water to evaporate from a 5” diameter container?

Explanation:

In the air, a salt solution will evaporate more slowly than pure water.

What is Evaporation?

The process by which a liquid transforms into a gas state is called evaporation. A surface phenomena, that is. The amount of evaporation depends on the humidity. If the air is humid, it is virtually saturated, which means that evaporation will occur at a much slower rate.

Since evaporation takes place on the liquid's surface, the salt molecules that are present on the water's surface prevent as much water from evaporating. As a result, salt water evaporates more slowly than pure water.

As a result, the salt solution will evaporate from the air more slowly than pure water.
