For the research, one would naturally learn about mint itself. What is the difference between peppermint and spearmint? Peppermint is a low growing creeping plant that produces a strong scented aromatic oil. Whereas Spearmint grows more upright and does not produce an oil and has a different flavor. The website "http://bonnieplants.com/growing/growing-mint/" states that mint is a fast growing plant that spreads.…
A thermometer was used to measure the temperature of the water and the air in degrees Celsius…
What types of light can a light sensing BlueBot detect? Lights are used for many everyday tasks, and many days they go unnoticed. There are many types of lights, such as Ultraviolet, Infrared, fluorescent, and LED lights, and they all can do different things. Ultraviolet light can be used as a way to light up certain types of clothing, or it can be used to sterilize food.…
Magnesium Chloride as a Deicer Emily Lekah Fall 2015 CHEM 1066 October 15, 2015 University of Minnesota Abstract The purpose of this experiment was to evaluate magnesium chloride as a deicer. To be a good deicer, a salt must be able to lower the enthalpy when is mixed with water. This will cause an exothermic reaction and release heat.…
Question: Which salt type can melt ice at a quicker rate, Magnesium Chloride (MgCl₂) or Sodium Chloride (NaCl)? Background: The different states of matter are solids, liquids, and gases. Solids have a definite shape and volume, and have very little energy because the molecules in a solid are in a fixed position. Liquids have a definite volume, and have the second most/least amount of energy between the three states because its molecules move freely but closely together.…
With the temperatures falling, you're most likely searching for an activity for the entire family. Ice skating is a terrific way to get much-needed exercise in the winter when it's too cold to play outside. Whether you're an adult skating after a long absense or lacing up skates on your children for the first time, there are ways you can avoid injury on the ice. When it's your first time skating, you should choose figure skates over hockey skates. The blades on figure skates are longer and provide more stability.…
The experiment that I will be conducting focuses on how fast one tablet of Alka seltzer can dissolve in various temperatures of water. The core of this procedure is to determine the impact that temperature has on how fast something dissolves. My hypothesis for this experiment would be that the Alka Seltzer that dissolves the fastest would be the one that was placed in the water with the highest temperature. There will be controlled and manipulated variables explained throughout the experiment. The two main things used in this experiment will be the solute and the solvent, which is Alka Seltzer and water.…
Sungwoong Lee My brother and I watched the film Chasing Ice together on Wednesday. I watched all of the trailers that were on the list. However, among those 5 films of the list, I decided to watch the Chasing Ice because the scenery of Arctic was magnificent and I’m also interested in topic of global warming and wanted to know more about how the global warming affects to the glaciers in Artic.…
Increasing temperature, ocean acidification, and melting and refreezing of the Arctic Glaciers are three concepts that prove why global warming is occurring. Increasing temperature will be the first topic of discussion. The temperature of the Earth has been on a steep incline from past years. “Carbon dioxide production has increased 30% since the last Industrial Revolution” (NASA 2017).…
Since most of the human body is made of water and by lowering the body below the freezing point of water will result in massive ice formation. Cryonic facilities can’t simply put patients into a vat of liquid nitrogen because their cells would freeze and simply shatter. Because of this reason, patients are protected from ice damage by using a mixture or agent (sort of a human antifreeze) to reduce, or even eliminate, ice formation. Conventional bypass technologies are used to circulate the solution throughout the body. When enough water is replaced with the agent, the patient is maintained at cryogenic temperatures for long-term care.…
The melting point of a substance is best described as the temperature at which a solid becomes a liquid (Bruice 2014). On the molecular level, when a compound melts the forces between the molecules become weaker. This is because when a substances heats up the kinetic energy between the molecules increase causing the molecules to vibrate. When the vibrations become strong enough for the molecules to move around and pass other molecules, the compound that is being heated up starts to melt and become a liquid.…
The melting trend in northern Canada is increasing. Rapidly Over the past 30 years, the annual average sea-ice extent has decreased almost one million square kilometers ( source 12). Proof that it is possible to slow this down is on January 1st 1989, the day The Montreal Protocol came into affect. It was an international treaty to phase out various products that were contributing to ozone depletion. The proof was in the animals living in the arctic; they were developing skin cancer and cataracts in early stages of life due excessive amounts of UV radiation that wasn’t being filtered out in the atmosphere.…
Temperature was checked with a thermometer once all the ice had melted. The prepared bath was then…
- Heating Capacity How much area can the heater warm up? This is one of the chief questions that need to be answered, in order to enforce any purchase. Most people understand that area and the time taken to warm up are quite dependent on each other. When opting for a commercial electric heater you need to see whether the heater will meet you demands in terms of space and capacity. Even if you use it for outdoor or indoor heating, a heater is bound to fail if the heating capacity does not complement it.…
Cool water was placed into the calorimeter and its temperature recorded, while an equal weight of water was heated to 35.3 ⁰C. The heated water was immediately poured into the water in the calorimeter and the temperature was recorded. The water equivalent of the calorimeter could then be calculated. Approximately 100 g of cool distilled water was placed into the calorimeter and the initial temperature recorded. Solid sodium sulphate decahydrate crystals of 4.00 g were added to the water in the calorimeter and stirred until it dissolved.…
