Temperature

sure the solid was secure at the bottom of the capillary tube so it didn’t just fall out once you tip it upside down inside the Thiele tube. In addition a problem with heating the Thiele tube was that we couldn’t tell the precise reading of the temperature as the thermometer was constantly going up at a fast rate which meant it may have not been totally correct. The last problem I had was drying out the paracetamol. Some of the water was left behind so I couldn’t get it…

Raj Bose IB Chemistry HL Period 4 15/10/2014 Research Question: How does increasing the concentration of copper (II) nitrate solution in a voltaic cell affect the voltage produced? Variables: Variables Description of the variable Method of controlling variable Independent Concentration of copper (II) nitrate solution used in each trial of the experiment. N/A Dependent The voltage being produced by the two electrodes which is measured by the voltmeter N/A Controlled Concentration of the zinc…

ULTRALIFT What HIFU? High Intensity Focused Ultrasound (HIFU) lifts and tightens skin for a nonsurgical face lift and neck lift. It is truly remarkable, breakthrough in technology offering a non-invasive face lift. HIFU technique uses the power of Ultrasound to safely lift and tighten the skin. Ultrasound is nothing but the form of energy which is significantly different than light such as IPL and lasers or Electrical energy. HIFU technique can protect the skin surface. In HIFU technique,…

live in a area where the roads could freeze because the salt would take up space for melting so the rate of freezing is changed. The formula to changing Celsius to Fahrenheit is °C x 9/5 + 32 = °F(°F - 32) x 5/9 = °C Adding salt could make temperatures drop to icy things. It would make it melt faster. Water freezes slower because the water molecules reach the surface if the ice. Melting rate does is not changed by salt. This is how people back then would create ice cream by using somewhat…

Inspected Now One of the main reasons to have your cooling system inspected is that this system helps to keep your car’s engine from overheating. An overheated engine can be costly, and the engine may become even hotter in cold weather than when the temperature outside is warm. Your car’s engine is the heart of the vehicle, and you may require more from your vehicle in fall and winter than in spring and summer. You rely on the electrical system more because the days are shorter and you need to…

energy is generated than can escape into the surrounding medium, with the result that the temperature of the reactants is raised to accelerate the reaction even more." (Web) As a result, it will take more time to reach this ideal temperature so energy can escape if a candle has a lower initial temperature. A familiar example is a lighted match. When a match is struck, friction heats the head to a temperature at which the chemicals react and generate more heat than can escape into the air, and…

other thing mold needs to grow is a temperature no lower than 40 degrees F and no higher than 100 degrees F. My house is not ever lower than or higher than these temperatures so this made sense. Another thing I was curious about was how mold spread. One way mold can spread is through spores. Spores can survive in almost any type of environment. Spores turn into mold when they are released and land in a place that has water, oxygen, and the proper temperatures. Spores are not necessarily…

Each experiment yielded its own unique set of observations, calculations and results. The first experiment studied the relationship between volume and pressure, while keeping the amount of the gas sample and temperature constant. Table 1 shows the atmospheric pressure recorded during the experiment. Atmospheric Pressure (mm Hg) 644.0 mm Hg Table 1. Atmospheric pressure was recorded using barometer in lab next door. This atmospheric pressure is of the lab next door, and is not the atmospheric…

five seconds and dropping it in the hydrogen peroxide. With the timer for the coffee filter to sink and rise • Make sure to record the time taken for the coffee filter to sink and rise and the temperature of the solution • Each temperature trial should be conducted at least four times • For each temperature calculate the average time taken (“Enzyme-Catalyzed…

In the average life span, a human will experience extreme variations in temperature. Due to the weather conditions we face it is common to reach temperatures that are below the average temperature. When the body experiences low temperatures it will begin to lose heat and the normal functions begin to reduce causing many issues. According to Canadian Medical Association Journal, “Hypothermia is defined as a core body temperature of 35°C (95°F) or lower. It should be treated as a medical…
