Pre-Lab Questions1. Explain how hydrogen bonds are formed between molecules of water. 2. Describe what is surface tensionPart A: Surface TensionIntroduction: In this investigation, you will examine the property of surface tension. The question of theinvestigation is, “How many drops of water will fit on a penny?”Hypothesis:Materials: penny, eyedroppers with water and rubbing alcohol (labeled “A”)Procedure1. Draw a chart for recording data. There will be three trials with each liquid.

2. Place the penny on a flat surface. Using the eyedropper, put drops of water on the penny one at a time. Stop when water begins to spill off the surface of the penny.3. Record the data. Repeat twice with water. Repeat three times with rubbing alcohol.Results: Calculate the average of the three trials. Show your work.Part B: Capillary ActionIntroduction: In this investigation, you will examine capillary action. The question of the investigation is,“What will happen to an ink spot when placed on filter paper soaking in water?”Hypothesis:

Materials: two strips of filter paper, 2 plastic cups, water, felt-tip markerProcedure1. Use the felt-tip marker to place a dot 1 cm from the bottom of each of the strips of filter paper.2. Draw a chart for recording data. Observations will be made of both strips before placing the strips in the cups and after 10 minutes have passed.3. Place one strip in the cup with approximately 5 ml of water and one in a cup without water. Make sure that the water level remains below the ink spot.
