For the specific sample that you used, briefly explain why you think that the purity was not 100%. The scraps of aluminium were not pure because of the oxidation of the surface of the container along with the coats of paint and plastic that covered the aluminum. Name two other aluminum containing substances with which you are familiar that could be analyzed by the method used in this experiment. Two other substance that contain aluminum that could be analyzed using this experiment are window…

How does thermochemistry look? Thermochemistry is the different kind of energy’s. When cold water touches hot water the water temperature changes. Thermochemistry does not have a shape of form, like air you can’t see it but you can feel it. Thermochemistry happens in our body as well, when the body exercises it releases negative energy and that makes your body tired that make negative energy. Positive energy happens when you eat food your body makes it energy for you to use as the day happens.…

Heat has been a problem to mankind for millions of years. It has caused heat strokes, heat rash, and dehydration. A way to obstruct this problem is color. Different colors absorb heat worse or better. The reason colors absorb light is because when color absorbs light, it turns it to thermal energy. If a color absorbs lots of energy, It makes lots of thermal energy (Morton, J. L. "Color and Heat Absorption"). Scientists believe that darker colors absorb better, and lighter absorb worse…

The product we are proposing is a fridge accessory that will help owners manage their fridge items as well as their expiry dates. This product will have the capacity to store the name of the fridge item as well as the date the food needs to be consumed by. The product will have the option of a touch screen keyboard or voice control for communication. With this, the product is able to store home cooked meals and and fresh foods as well as pre-packaged items. When the expiry date of a product is…

Heat water in a pan or beaker until it is boiling vigorously. While the water is boiling, measure the mass of your metal object, marking off your answer to one more decimal place than what the scale marks off. Once the water is boiling, drop the metal into the water, leaving it in for about five minutes to allow it to reach the temperature of the water (100.0 °C) Place one Styrofoam cup into the other. This will be your calorimeter. Measure the mass of the calorimeter. Fill about ¾ full with…

From replacing loose roofing shingles to a water heater repair in Longview TX, there are an overwhelming number of tasks necessary to clean and maintain your home. These tasks are essential for your home’s appeal, function, and value, but you may not be placing enough emphasis on your plumbing. Considering the average lifespan of a traditional water heater is about 10 years, you may need a complete replacement. Fortunately, replacing with a tankless model offers numerous benefits. Energy…

weather or if the windows are open, this child is may be in danger and the person who left her unattended has violated the Florida Law which makes it illegal to leave a child under 6 years old alone in a motor vehicle. A car can heat up by 20 by degrees in just 10 minutes and can heat up to 110 degrees or more even with outside temperatures in the 60’s. Did you know that a temperature of 107 is deadly to a child or that a child’s body temperature can rise up to five times faster than an…

calorimeter we used by determining the heat given off from pringles and calculate how much energy was released by the burning food substance. In addition, we can also use the concept of conservation of energy that energy cannot be created or destroyed. Introduction In order to complete the snack energy lab, calorie and calorimetry will be use as a major technique. By burning pieces of food, the chemical energy stored in molecular bonds is released as heat and light. The heat can be measured in…

Name: Heat stroke (hyperthermia) Overview: Hypothermia occurs when the body temperature falls below the warning level and the heart can no longer pump enough blood to make it flow through the whole body. Hypothermia occurs when the temperature of our body drops below 35 degrees Celsius or 95 degrees Fahrenheit. Causes: Hypothermia caused as a result of exposure to cold weather- without adequate protection - for an excessive time, in wherein the body is no longer able to produce the heat…

graphs, cref{fig:Graph-Enthalpy-Jun2} and cref{fig:Graph-Enthalpy-Jun3}. The change in enthalpy helps in understanding the amount of heat energy evolved from the heat exchange process whereas change in entropy helps in understanding the amount of energy lost due to irreversibility at each stage of the operation. In case of SAH, $vartriangle$h is computed based on specific heat capacity and temperature of air at inlet and outlet and $vartriangle$S is computed based on the temperature and pressure…
