Is There a Difference in Evaporation Rate of Different Liquids?

evaporation

evaporationEvaporation Rate of Different Liquids: We know that all liquids can evaporate at room temperature and normal air pressure. Evaporation means the process of transformation in liquid from its liquid state to gaseous phase. Evaporation is not the same as boiling point. We will try another project on boiling point later. However, currently we have water, coconut oil, salt mixture (salted water), and nail polish remover in our hand. Let’s see whether they evaporate at the same speed or at different speeds.

Project Question:

Do liquids of different kinds evaporate at different rates?

Things that you need:

  1. Four beakers with measures indicated on them
  2. Water
  3. Water mixed with salt
  4. Coconut Oil
  5. Nail Polish
  6. Project data card

Procedure:

Step 1: Pour each liquid in each beaker by equal quantities.

Step 2: Note the starting amounts of liquids (must be equal at the beginning).

Step 3: Keep the beakers in a dry place in room temperature.

Step 4: Record the levels of liquids from each beaker every morning for 5 days.

Step 5: Conclude the project from your observation.
