How do you test the absorbency of paper towels?
Hold the towel in water for 10 seconds, then lift it up out of the cylinder and allow to drip into the cylinder for 5 seconds. (The purpose for doing this was to make sure the test showed what the paper towels were absorbing AND keeping in.
How much water does a paper towel absorb experiment?
Each paper towel was tested three times. The results showed that Bounty absorbed an average of 16 mL of water, Viva absorbed an average of 15 mL of water, and Sparkle absorbed and average of 14 mL of water.
What is the dependent variable in the paper towel experiment?
The dependent variable is what is measured during an experiment. The dependent variable depends on the independent variable. In this experiment, the independent variable was the kind of paper towel, and the dependent variable was the volume of water each kind of paper towel absorbed.
Why does the paper towel stay dry in water experiment?
Air is less dense than water so it is able to stay on top of the water. The paper towel will not get wet as long as the air stays in the glass.
Which paper towel is the strongest experiment?
Bounty paper towel
The Bounty paper towel was the strongest. Zoë Miller After being soaked, the Bounty towel held an impressive 43 ounces or 2.69 pounds.
Why are some paper towels more absorbent than others?
The answer is in the process that is used to make kitchen paper towels. Kitchen paper towels can absorb more spilled liquid because the paper making up a paper towel is woven together loosely, which allows liquid to travel between the paper fibers in the towel, making it a more absorbent paper product.
How does paper towels absorb water?
Paper is made of cellulose, which water molecules like to cling to. Paper towels are especially absorbent because their cellulose fibers have empty spaces—tiny air bubbles—between them. Water molecules, which like to stay together, follow the one another as they are absorbed by the cellulose and fill the empty spaces.
What paper towels absorb the most water?
We tested paper towels from Brawny, Marcal, Sparkle, and Bounty to see which was the strongest and most absorbent. Bounty was the strongest and most absorbent paper towel we tried.
Does the brand of paper towel affect the absorbency?
The results of the experiment were that the Sparkle brand paper towels were the most absorbent. It absorbed on average, 50ml of water, when the Bounty brand paper towels absorbed only 44.75ml of water.
What does good absorbency mean?
: the quality or state of being able to draw in or soak up. absorbency. noun.
What happens to a towel when it is soaked to water?
When the paper towel is dipped in water, some of the water sticks to the paper towel and gets it wet. There’s a force between the water molecules and the molecules in the paper towel. That’s called adhesion. The water also sticks to itself.
What happens when paper gets wet?
When paper gets wet, however, those strong hydrogen bonds between cellulose fibers get broken down and the fibers separate more easily. This happens because water is made up of hydrogen and oxygen. Thus, the paper becomes weak and much easier to tear.
What paper towel is the most absorbent?
During this investigation, I will be aiming to find out which paper towel brand, out of Kleenex brand Viva, Handee Ultra, Coles Ultra or Coles Greenchoice, absorbs the most water. I think that the paper towel brand Handee Ultra will absorb the most water, as it advertised as the most absorbent paper towel in the available market.
What makes a paper towel more absorbent?
The answer is in the process that is used to make kitchen paper towels. Kitchen paper towels can absorb more spilled liquid because the paper making up a paper towel is woven together loosely, which allows liquid to travel between the paper fibers in the towel, making it a more absorbent paper product.
Which paper towel is the strongest hypothesis?
Abstract The hypothesis is that Naturale is the strongest toilet paper because it has fewer gaps which mean more fibre that gives the toilet paper more strength. This hypothesis was tested by two experiments that involved three trials each comparing the strength of each brand toilet paper.
What makes a paper towel absorbent?
Paper towels absorb water because the fibres used to make them are loosely woven, allowing water to be soaked up, even against gravity. They are made of cellulose fibres and large molecules that are composed of many small molecules linked together.
