A student team places 100 milliliters (mL) of distilled water into each of two graduated cylinders. One is placed in a humid room, and one is placed in a dry room. The team measures the remaining volume ofwater in each cylinder every 5 minutes. To produce a generally valid conclusion about the relationship between humidity and rate of evaporation, which experimental condition should be true?O Both test cylinders had the same mass.O Both water samples took the same amount of time to evaporate.O Each room used had the same temperature.O Each room used had the same volume.

Question

A student team places 100 milliliters (mL) of distilled water into each of two graduated cylinders. One is placed in a humid room, and one is placed in a dry room. The team measures the remaining volume of
water in each cylinder every 5 minutes. To produce a generally valid conclusion about the relationship between humidity and rate of evaporation, which experimental condition should be true?
O Both test cylinders had the same mass.
O Both water samples took the same amount of time to evaporate.
O Each room used had the same temperature.
O Each room used had the same volume.

Expert Solution

Step 1

Humidity is amount of water vapors present in air. Evaporation is a process in which a liquid changes to gaseous state. As the experiment is done with distilled water, the gaseous form is water vapors. As humidity is high, rate of evaporation is low as already vapors are present in air.

To produce a valid conclusion, both the test cylinders should have same mass to hold the same quantity of water. As if quantity of water vary in cylinders it is difficult to compare the results.
