Essay on Heat Stroke

In the hot and cold pack experiment we found it to be a chemical reaction An exothermic reaction is when the substance releases heat energy. An endothermic reaction is when the substance absorbs heat energy. In our experiment we created a cold pack. We indicated that the reaction for this experiment would be exothermic. We think this because exothermic is releasing the heat which would make it cold. In our lab our guiding question was, which of the following substances would make an…

My science fair project involves soda bubbles and temperature. I chose this project because I’m interested in the viscosity(a chemical in soda) that is part of a soda/liquid, and how the viscosity is affected by the temperature of the liquid. I am also interested in bubbles specifically their length of time, so it would be interesting to see how the length of time is affected by temperature. The question that I am going to answer is, how does the temperature of soda affect the length of time of…

the trick? There are multiple ways to test this experiment, but only one way to find out. There are a couple different ways how cold temperatures can remove the warm air from the lukewarm soda. The first of these is conduction. Conduction is when heat is transferred by direct contact. An example of this would be if you put a metal spoon in a heated drink, in a short amount of time you would feel the spoon heating up. It happens…

I have chosen to put a candle inside of the shoebox to represent the main character in the book, John, or Number Four. In the story John Smith has is immune to fire on the exterior of his body, but not the inside of his body. John Smith is able to control and create light, and because of that, he is also able to control fire. This power of Johns doesn't just allow him to control fire, but also energy itself making John's power limitless. There is a thermometer in the shoebox because the…

temperatures of the shark are as much as 10 oC warmer than the water that it swims in. This confirms that a system of large retia mirabilia in the circulatory system function as heat exchangers. (2) The shark does not thermoregulate and muscle temperature changes slowly as water temperature changes. Because of these heat changes the shark can maintain itself for more than a month on a single large meal. Speed of locomotion plays an important role in an animal’s biology and ecology and is of…

How A Metal Roof Can Save You Money If your home’s asphalt shingles are falling off, blistering, and bending, you need to start thinking about roof replacement. Thankfully, you do not have to use the same roofing material that your home currently has. Metal roofing can actually provide many benefits over asphalt shingles, with several of them being financial related. Here are 4 ways that metal roofing can save you money. You Can Avoid Removing The Existing Roof If the only thing that is bad…

dioxide will be released into the atmosphere, so the global temperatures won't rise as much. The global temperatures will still rise for a while, however, because the greenhouse gasses will still linger in the atmosphere and continue to radiate the sun's heat to the surface. Eventually, the global temperatures will be able to stabilize. To stop pollution, people need to dispose of things properly. Dispose of chemicals, batteries, etc. in the proper special bins, and recycle paper and plastic so…

reaction is called sublimation. Sublimation is when something solid goes straight to gas skipping the liquid phase. So because the water is warm it heats up the dry ice which causes it to form a gas. The gas is carbon dioxide. The temperatures of everything are very strange. The water cannot be cold when trying the experiment because it will not heat up the dry ice and create carbon dioxide gasses but it will probably freeze the water. Dry ice is temperatures below freezing point and the water…

commonly used techniques of desalination involved distillation and evaporation. Solar desalination relies on the sun’s energy to create water vapor, which produces condensation of fresh water. Similar to the first part of the water cycle, the sun heats up the water, which creates water vapor. The water vapor rises and creates liquid condensation. This liquid condensation does not contain salt, but fresh water. The salt remains at the bottom of the water. Solar desalination is not used…

4.8 How do the Hydropower Plants Work? Hydropower is the combination of head and flow. The Head is water pressure created by the difference in elevation between the water intake and turbine, expressed as a distance (feet or meters) or as pressure (pounds per square inch). Similarly, flow is the quantity of water, expressed as volume per second or minute (gallons per minute, cubic feet per second). In a typical hydropower system, water is diverted from a stream into a pipeline, where it is…
