Meta: The location of your thermostat matters when it comes to your home’s overall comfort. Here’s what you need to know about placing your thermostat in the ideal spot. Did you know that the location of your thermostat is important for the overall comfort in Washington D.C.? Here’s what you need to know about placing your thermostat in the ideal spot. Keep Out of the Heat Your thermostat senses the indoor temperature and makes the necessary adjustments to your unit. If you place the…

The guiding question is that which changes are examples of a chemical change and which are examples of a physical change? Our claim is that 100ml water mixed with salt paraffin wax melting are examples of physical change. While magnesium strip heated, sodium hydroxide and copper chloride mixed and hydrochloric acid added to sodium bicarbonate are chemical change. For task 1, we measure 100ml of water, weigh 5g of table salt and mix the 5g of salt and 100ml of water. Stir until change is seen.…

PCR History The invaluable molecular technique known as PCR, or the polymerase chain reaction, was discovered by a biochemist named Kary Mullis. Mullis was doing research in the early 1980s at a biotechnology company in California when he initially thought of the idea regarding PCR. PCR was developed by a combination of several techniques already in existence; the synthesis of oligonucleotides and their utilization to synthesize new copies of DNA that were specific using DNA polymerases. Mullis…

Has the world grown so dependent upon nuclear power energy that it ignores the price tag? Power reaped from nuclear energy by heating and pressuring water is known as nuclear power. Controversies surrounding nuclear power come in various forms, however, the financial aspect is grand. In their recent work, the Union of Concerned Scientists (UCS), a nonprofit organization composed of numerous scientists, discovered actual costs of implementing nuclear power as an energy source. Within the article…

Did you know that the Great Barrier Reef is main contributor to the Australian Economic, contributing $6.4 billion a year! Many Australians believe a price cannot be placed on the Great Barrier Reef, resulting in it being Priceless! The Reef is one of the top tourist attractions in Australia, with a $56 billion value along with $3.2 billion for recreational use. Why do the Australian’s, tourist and the economic value of Australia Need the $56 billion reef? Just to name a few reasons why: 1. The…

Changes in the temperature coefficient of resistivity correlate with corresponding temperatures. The heating time is related to the size of the sample, because the lateral boundaries will affect the specimen. In order to measure stable values of thermal conductivity, the sample size must be considered during the period which heating is…

determine the concentration of the sulfate, the precipitation of Barium sulfate is done first by adding the sulfate solution with hydrochloric acid, then heating while stirring it. Next is the washing and filtration of the Barium Sulfate precipitate, using a vacuum pump and a crucible. Lastly, is the drying and weighing of the precipitate by heating the crucible in the oven and cooling it in a desiccator. The average weight of the precipitate is 0.1602g. The gravimetric method is useful in…

In the short story written by Tim O'Brien, "The Things They Carried," O'Brien writes about a platoon of American soldiers fighting on the ground in the Vietnam War. He writes about the items soldiers carried on their backs and on their minds. This is similar to other wars such as the Gulf War in 1990. However, the technology, geographical features, and the politics of the two wars have several differences. There are similarities between Vietnam and Iraq: In both conflicts, there was pressure…

type of light bulb available in the marketplace. Likely one of the largest consumer of electricity at the pharmacies is the outdated air conditioning and heating units. It is recommended from the Getting Green article by Wick in the Pharmacy Times that pharmacies update old equipment to new energy efficient ones and adopt energy saving heating and cooling practices, however it may be difficult to change due to the property being leased. Waste Disposal Currently the city of Anaheim, in which…
