Three paper towels A, B, and C where tested on absorbency. This experiment was tested twice. Paper towel A was 26.5 by 28 centimeters. Paper towel B was 26.5 by 28 centimeters. Paper towel C was 15 by 28 centimeters. Scissors were obtained and each paper towel was cut to 13.5 by 15 centimeters. The weight of the three paper towels at this size was 0.9 grams dry for paper towel A, paper towel B weighed 0.8 grams dry, and paper towel C weighed 1.2 grams. Three beakers weighing 12.2 grams each were obtained. Each beaker was filled with 100ml of water with the outcome of them weighing 128.1 grams each. The weight of each paper towel dry was deducted from the weight of each paper towel. Paper towel A was left to soak for seven seconds.

Absorbency affects: skin comfort, static build-up, dimensional stability in water, stain removal, water repellency, and wrinkle recovery.

The results of the experiment for the test of absorbency were that the Sparkle brand proved to be the most absorbent. The average amount of liquid that the Sparkle brand paper towel held was 17.4 mL, which was 4.6 mL more than the Decorator brand held. The Decorator brand only held 12.8 of liquid.

The reason for the experiment is to see which liquid makes the Jelly Marble grow the most. Jelly Marbles are clear spheres made from an superabsorbent polymer and about 99% water. This makes it so that it absorbs water very quickly. If the jelly marbles are soaked in 70% rubbing alcohol then the growth will decrease.

The reason for the plan of this experiment is not only to find out which brand has better absorbency, but

Gorilla Glue #4 on Fire cannabis strain has a strong smell of diesel but the taste is similar to coffee that has gone stale. This strain is mainly grown indoors. The THC level is about 25-28%. This marijuana plant is light green in color.

Not much people know, but polyester is also very harmful. The raw material itself is used to produce polyester oil. Unfortunately, oil belongs to the non-renewable category. With oil as one of the top resources needed in the world, polyester production is not sustainable. It is also non-biodegradable. In other words, oil is not decomposable. So when these textiles end up in a land-fill, it will remain there for a long period of time. About twelve billion pounds of post consumer textiles waste ends up in land-fills every year and half of them are polyester.

To test the absorbency of each of the paper towel brands they were folded into 6th’s and placed into a 250 mL glass beaker containing 100 mL of tap water (H20). Each of the paper towel brands absorbed water in the beaker for 30 seconds and were lifted from the water for 30 seconds so that the excess water may drop off. The tap water remaining was later poured back into the 100mL to measure the paper towel absorbency. To get the total amount of tap water (H20) absorbed, the formula used was 100mL – X mL =

The make-up of filler compound consists of multiple elements, including polyester (fibreglass) resin and talc. The talc powder incorporated is the very same as everyday talcum powder. But the grade of the talc is what dictates the type of filler produced.

The top of tennis court could be hard or soft predicated on your preferences. But today people prefer to perform on smooth surfaced tennis court, the Acrylic/Cushion Tennis Courtroom. Going by the existing demand the most favorable may be the standard 3 coating color system tennis courtroom. Once a coating of resilient coating is used on the hard coating it outcomes in the cushion courtroom. Among the acrylic resurfacing item and the courtroom paint the cushioning can be used.

In recent years, a new criterion was added: the impact on the environment. Those who are concerned about the future of our planet generally opt for washable pads. Make cotton flannel or silk or wool, they are generally comfortable and dry. However, they lose this quality when wet. Moreover, they are generally less absorbent than disposable compresses. However, you will find on the market, products bearing a plastic film between two strips of absorbent cloth. The risk of leakage are reduced. Unless you choose the conical compresses, these products are generally not very discreet. These compresses, often flat, sometimes create

Polymers effect every ones life almost every day allowing us to make many valuable items that can help make our lives easier including plastic, PVC, and shellac there are also natural polymers that we benefit from such as rubber and amber. Polymers are truly a great and very beneficial item to everyone for they are tough, durable, and cheap but they are also recyclable which can be very beneficial to our environment and societal needs. The only negative effect is when it is not properly disposed but this is really the users fault not the actual item its self

The purpose of this lab was to create soaps and detergents and test their cleaning ability. We created four different soaps and two detergents using different starting materials composed of oils and fats for the soaps and lauryl alcohol and sulfuric acid for the detergents. Soaps are created by a process called saponification, which is the formation of a salt by combing an acid and a base.1 Soap and detergent are effective cleaning agents because they have hydrophilic and hydrophobic ends.1 The hydrophobic ends interact with the dirt and oil while the hydrophilic ends interact with the water molecules effectively washing the dirt and oil away.2 While soaps and detergents are very similar in their cleaning ability, they have a major difference being that soaps are made from natural products and detergents are made from synthetic materials.3 In order to make the soaps, we used four different starting materials including lard, shortening, olive oil, and vegetable oil.
