by water, and the substance is ignited and the change in temperature of the water is measured. (Cal …) The measurements as well as the mass and the specific heat, “which is the amount of heat required to raise an objects temperature by one degree Celsius” (Chem …), are used in the calorimetery equation. Which is specific heat multiplied by the mass in grams multiplied by the change in temperature. (Cal …) The overall goal was to capture the energy of a chip. As a class on average we saw that…
video. "With heat strokes or heat injuries, a lot of them are going to have irreversible brain damage.", San Antonio Fire Chief Charles Hood said. The trailer did have an air conditioner, but it did not work. San Antonio on Saturday was 38 degrees Celsius (100 degrees Fahrenheit). The youngest of the victims hospitalized are 15 years old, the fire spokesman said. However, according to Fox News (July 23, 2017), the man connected to the human trafficking case is expected to be charged. Sixty year…
climate is cold and windy and rainfall is scant. Arctic tundra lands are snow-covered for much of the year, until summer brings a burst of wild flowers. The Arctic tundra, where the average temperature is 10 to 20 degrees fahrenheit (-12 to -6 degrees celsius), winter precipitation usually consists of dry snow while the summer growing season is just 50 to 60 days, when the sun shines 24 hours a day. The highest temperature is 50 degrees. The nitrogen cycle in the Arctic tundra is when animals…
Primack (2013) led a study that shows the effects of warming temperatures on winning times in the Boston Marathon. He and his three co-authors, Dr. Abe Miller Rushing, Dr. Nathan Phillips and Dr. Robert Kaufmann, examined the timing of the Boston Marathon runners from the years 1933 to 2004. They found that when warmer temperatures and headwinds occurred the day of the race, the runners were indeed slowed down. The reasoning for this research was to further their focus on climate change from…
production of collagen which is found in ligaments and tendons. (Ultrasound Therapy). Hyperemia, also known as increased blood flow, is one of the distinct benefits of ultrasound use in therapy because it heats the tissue to approximately 45 degrees Celsius. (Therapeutic Ultrasound). It is important not to heat the tissues too much because damage can occur as a result of too much heat. Mechanical ultrasound therapy uses pulses of sound waves rather than continuous. Mechanical ultrasound still…
Azo-Tetrazolate--Pentahydrate (SAT) Approximately 2.15 g of Aminotetrazolate monohydrate was added to approximately 62.5 ml of 2 M sodium hydroxide. While being stirred, the solution was heated, increasing its temperature up 10 degrees Celsius, up to 60 degrees Celsius. Over a one hour time period, potassium permanganate (an amount of 2.5 g) was added in increments. After this, sodium sulfite was added at a slow pace, and powerful stirring destroyed the remaining permanganate. To determine the…
dishes. Sixty different agar dishes were labeled based on the antibiotic used. Then the dishes were left to dry and solidify at room temperature for hour to rid of moisture. After an hour, the dishes were placed in a refrigerator at three degrees Celsius. The agar plates were monitored every few hours to make sure that the plates did not accumulate moisture. If there was visible condensation on the agar plate, they…
In Period 11 of lab, two experiments were conducted: one investigative and one preparative. Both experiments demonstrated the theory and concepts behind electrophilic aromatic substitution. As the term states, the experiments deal with the chemistry of six membered ring compounds and their transformations through electrophilic substitutions. This type of reaction transforms the aromatic compound by allowing various functional groups to be attached to it. The general process of this reaction is…
In recent years, as technology advances faster than ever, there has also been a huge surge in the awareness of global warming and greenhouse gas emissions. In the article, The Fast-Approaching ‘Point of No Return’ for Climate Change by Karin Kamp and John Light, top climate scientists warns the international policymakers about the current and potential permanent damages to our environment, sets a target level for lessening harmful greenhouse gases, and urges policymakers to push for new policies…
concentration of indium is increased [6]. This is not a cost effective solution as indium is very costly. Titanium oxide nano particles addition led to temperature changing from 217 to 217.64 degree Celsius [7]. Zinc oxide bearing SAC had temperature of about 222.16 High Temperature Electronics 6 degree celsius when zinc was about 0.5% by weight [8]. From this it can be conclud-ed that there no major effect on melting temperature. 2.2.2 Wettability It is the ability of…
