lead, zinc, water, and ethanol were heated, then ethanol will absorb the most heat because it’s boiling point is lower (70°C) than the rest of the materials. This investigation was valuable because it creates further understanding in the way thermal energy works for different substances. Procedure A hot plate was heated at 85°C. A beaker filled halfway with water is placed on the hot plate, and then was heated up to about 70°C. 5 g of the substance was then inserted into a test tube and then was put

temperature of the dry sand would drop faster than the wet sand due to the fact that water retains heat so it would take longer to cool down. Furthermore, it would be hypothesized that the heat energy released by the wet sand would evaporate into the atmosphere. Water takes energy to evaporate and it would get its energy from heat. When the water evaporates, it cools the surrounding area. This is also how sweating works. When sweat evaporates, it cools down the body

Many people underestimate themselves because they are intimidated by far more talented people but that's not an excuse to stop trying. Derek Jeter once said, “There may be people who have more talent than you, but there's no excuse for anyone to work harder than you do- and I believe that. In other words hard work beats talent. Usain Bolt the Olympic legend and a hard working high school runner Wes Schoenthal also live by this quote. These athletes are great examples showing that hard work does

"Shine!”I can hear the excitement in people’s voices as they call my name. I cherish those moments when I can feel the sunlight in my name warm the hearts around me. It is significant because, in 2005, our family lived in an antique basement condo in Sosa, South Korea. The sun would be bright outside, but in our condo, the high stairway left our underground home in the dark. My father prayed that one day I would be able to live where sunlight would freely shine on me. Hence, he named me “Shine”.

carbon-free energy but on earth it would take 100 times more heat than on the sun. Nuclear fusion is the big reason that the sun can give out energy, which happens when two or more nuclei come close and collide at at a very high speed creating one full nucleus. So almost everything you are doing right now is powered by nuclear fusion. It is also one of the most powerful sources. Fusion also happens on earth. The discoverer of fusion is Arthur Eddington. The word nuclear refers to the energy stored in

What is a supernova? - A supernova is a giant star that has an extremely high pressure core that contains vast amounts of heat. This causes atomic nuclei to get squeezed together and fuse, creating progressively heavier elements. (Hydrogen => Helium => Carbon). - If the star has about 8x the suns mass, it can create temp in excess of 5x10^8°C causing carbon to fuse. - Carbon the fuses into Ne, Mg and Na. Once the core heats up to around 1x10^9°C, Ne will fuse creating more Mg and some O. These elements

Word Count: Design Research Question: What is the effect of external temperature on muscle fatigue? Introduction: Muscular fatigue is caused by various things, one of which being insufficient adenosine ti-phosphate or ATP for short. ATP is an energy source that is essential to muscular contractions. Its production is primarily aerobic, however when there is insufficient oxygen for aerobic synthesis to occur, it will happen anaerobically which produces lactic acid as a by product ("Sports 'n Science”)

Recovery and performance preparation go hand in hand. Not only is it essential for athletes, like LeBron, to prepare his body for the next bout via nutrition to ensure he maximizes the uptake into his muscle and body stores, but it is equally important to use that nutrition to aid in recovery. Specifically, by decreasing inflammation and muscle soreness after the demands of each game. Inflammation can be experiences in both the bones and muscle, and is a result of repeated overuse without adequate

regular functioning of the human body, it requires a continual supply of cellular energy. This energy comes in the form of Adenosine Tri-phosphate (ATP), which provides the biological energy for cells to carry out their many functions. The energy in ATP is released through the process of hydrolysis and is broken down into Adenosine Di-phosphate (ADP) and inorganic phosphorus. It through the hydrolysis of ATP that its energy is released, allowing all the biological processes of the body to occur. However

#1) Explain how the physics of heat transfer make endothermy a particularly challenging strategy for organisms that live in water versus those on land. How is the issue exacerbated by fish respiratory physiology? Although being endothermic allows for the potential to maintain a constant internal environment that can ensure the most efficient metabolic and protein functions, this adaptation is incredibly energetically costly. Coupled with this, water in particular has relatively high thermal conductivity
