Whats the Science Behind Bubbles

Bubbles are beautiful, fun, and fascinating, but do you know what they are and how they work? Take a look at the science behind bubbles. What Is a Bubble? A bubble is a thin film of soapy water. Most of the bubbles that you see are filled with air, but you can make a bubble using other gasses, such as carbon dioxide. The film that makes the bubble has three layers. A thin layer of water is sandwiched between two layers of soap molecules. Each soap molecule is oriented so that its polar (hydrophilic) head faces the water, while its hydrophobic hydrocarbon tail extends away from the water layer. No matter what shape a bubble has initially, it will try to become a sphere. The sphere is the shape that minimizes ​the surface area of the structure, which makes it the shape that requires the least energy to achieve.​ What Happens When Bubbles Meet? When bubbles stack, do they remain spheres? No. When two bubbles meet, they will merge walls to minimize their surface area. If bubbles that are the same size meet, then the wall that separates them will be flat. If bubbles that are different sizes meet, then the smaller bubble will bulge into the large bubble. Bubbles meet to form walls at an angle of 120 degrees. If enough bubbles meet, the cells will form hexagons. You can see observe this structure by making prints of bubbles or by blowing bubbles between two clear plates. Ingredients in Bubble Solutions Though soap bubbles are traditionally made from (you guessed it) soap, most bubble solutions consist of detergent in water. Glycerin often is added as an ingredient. Detergents form bubbles in much the same way as soap, but detergents will form bubbles even in tap water, which contains ions that could prevent soap bubble formation. The soap contains a carboxylate group that reacts with calcium and magnesium ions, while detergents lack that functional group. Glycerin, C3H5(OH)3, extends the life of a bubble by forming weaker hydrogen bonds with water, slowing down its evaporation.

The On The Soil Lacks For Life On Mars Essay - 1342 Words

The soil lacks in nutrients. Therefore, greenhouses would have to be built and constructed in a way that the plants can adapt to the environment in almost a similar way to Earth. This would allow the plants to grow on Mars and over some time, create food for life on Mars. To have this greenhouse on Mars it would help grow plants for food, recycling and for replenishing the air. The main disadvantage to easily growing plants on Mars is the low atmospheric pressure that would make the plants act as if they are quickly drying out and dying. To get around this issue on Mars, we would have to be able to control the air pressure in the greenhouse. Scientists have stated that â€Å"A hydroponics system allows the plants to grow without soil, while artificial light ensures the plants are able to grow efficiently†. The food planted needs to have enough nutrients in its roots to be able to grow and have enough nutrients for humans to survive. For human survival, we would have to plant enough plants for some to be used as creating oxygen in the atmosphere and the edible portion to our nutrition. This would keep us healthy on Mars and be able to survive. Surprisingly enough, the Martian soil contains nutrients that is even more nourished than some of Earth’s soils. This means that the soil doesn’t lack any nutrients to grow food, it is the excessive volume of Perchlorate chemicals which would cause adverse effects on a human’s health. On Mars, as the plant grows, it starts to absorb theShow MoreRelatedThe Environment And Its Effects On The Natural Carbon Cycle1512 Words   |  7 Pagesenvironment.

Reduced diet diversity will be a challenge while astro-farming on Martian soil.

Drawings Leonardo Da Vinci and Michelangelo Essay Example For Students

Drawings: Leonardo Da Vinci and Michelangelo Essay Their drawings proposed a distinctive perception into each artists work and ideas. Both dad Vinci and Michelangelo employed drawing as a medium to develop new ideas and convey artistic thoughts. They used it to illustrate for themselves what they were going to do as a form of preliminary study. You can say that their drawings are in a way how they experimented and planned their work because they provided the foundation for their efforts as sculptors, painters, and architects. In addition their drawings re depictions of their experiences, ideas, and thoughts. According to Assayer recording the path of their artists hand directly on paper, artists also tint drawing to be a ready-made means to self-expression. It is as if in the act of drawing, the spirit of the artist finds its way to paper, (p. 1 70) Both artists depicted reality in all its detail and their figures were tilled with vitality and liveliness, As these two artists worked on their drawings to develop their new ideas and thoughts they provided a unique perspective of their individual Sino and outlook of life and the word around them. According to GIANT Editor (2005), to Leonardo dad Vinci, the nature and function of his drawings was mostly a way to document his scientific experiments in an extensive scope of grounds of perception and creativity as well as knowledge, a practice therefore in Which the intention to depict cannot be separated from the process of knowledge and which reflects his studies, experiences, inventions and considerations (GIGANTIC Editor, 2005) dad Vines main purpose was to recreate tauter in the most precise and technical way possible and he managed to do so by following the ingenious processes of his mind.

His primary focus was in human figures specially the male body and his drawings chart his relentless search to find poses that would most eloquently express he emotional and spiritual state of his subjects. (The British Museum, n. . ) Both Leonardo dad Vinci and Michelangelo conveyed their ideas, thoughts, and experiences in drawings that served as basis to most to their masterpieces, but without the intention, these drawings became masterpieces in their own, They provided a crucial link between their most prominent works in different fields of their artistic behaviors as well as a great connection to their experiences and ideas allowing their drawings to become the primary means of making art.
