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 is the question?
A. Does salt water evaporate when placed in a container?
B. How fast does distilled water evaporate if placed in a container?
C. How long does it take distilled water to evaporate from a 5β diameter container?
D. Does a salt water evaporate in the air faster than distilled water?
