Title: The Effect of Insulation Material on Heat Loss in Water
Introduction
Heat is a form of energy that can be transferred from object to another or surroundings but cannot be destroyed. Heat transfer can occur in three ways; conduction, convection and radiation. Conduction is where energy is transferred between objects which are in physical contact; convection is heat transfer of objects to the surroundings and radiation is transfer of energy in atoms from movement of charged particles (Damm & Fedorov 2005). Through these mechanisms, heat gain or heat loss can occur. Heat gain will make objects to be hotter while heat loss will make objects to be cooler.
In daily life, we tend to take initiates to ensure some things remain cool or hot. Insulation

The heat loss for this study is measured by determining the change in temperature of water in duration of one hour. Low change of temperature indicates heat has not been lost too much while high change of temperature indicates too much has been lost to the surroundings. Three insulating materials will be experimented in the experiment; paper, polystyrene and glass. These insulating materials will be in cup form where the water will be held. The experiment will be carried out in the lab where the surrounding has the same room temperature and air flow. Hence, these factors are controlled to remove confounding variables in affecting the results of the …show more content…
Then, a kettle is needed to boil water. Then some ice cubes or pipe water to bring down the temperature of boiled water to 60 ⁰C. Three thermometers to measure temperature in each cup and stopwatch to measure time is also needed.
First of all, the water is boiled to 100⁰C. Then, the water temperature is brought down to 60⁰C using tap water or ice cubes. The temperature is measured using thermometer. Then, 40ml of 60⁰C is poured into each cup. The stopwatch is stared at 0 min. the initial temperature is measured and recorded. The temperature for each cup is measured at 10th min, 20th min, 30th min, 40th min, 50th min and finally 60th min. All the temperatures is measured and recorded. The tabulation of the results will look as following:
Time (min) Temperature

    The experiment that I am doing is to see if the water temperature affects the reaction time of an Alka-Seltzer explosion. I believe that it will affect the time of how fast the CO2 builds up because the faster it builds up, the quicker the reaction and therefore the explosion comes faster. Alka-Seltzer is a drug that is used for heartburn and indigestion relief, along with many other things. When Alka-Seltzer was first introduced, it was advertised in comics in the newspaper in 1931.…

Next, the beaker was placed on a ring stand with a thermometer attached to the ring stand to record the temperature of the water. After the thermometer had been in the water for two minutes, the temperature was recorded. Following the recording of the temperature, a 10 mL pipet and a bulb was used to pipet 10.00 mL of distilled water into a clean, dry, pre-weighted 50 mL beaker.…

    The purpose of this lab was to find the most efficient way to transfer heat from a chip to a water beaker. The heat transfer was coming from burning a baked lay and through our calorimeter heat energy was pushed out. Then we took it another step further by modifying our calorimeter to capture even more energy. The overall purpose was to capture as much energy as possible. “Energy is the ability to do work, or the ability to elicit change in matter.”…

    The Thermodynamics of Potassium Nitrate Dissolving in Water Introduction: This experiment focuses on thermodynamics or the study of heat and molecular randomness. It helps illustrate how and why potassium nitrate (KNO3) dissolves in water. When it dissolves, it dissociates into potassium (K+) and nitrate (NO3-) ions. These ions can also recombine into solid potassium nitrate. This reaction can reach a state where concentrations of ions remain constant or Ksp; which stands for the equilibrium concentration for the solubility product.…

    PURPOSE/QUESTION The question that we will answer using this laboratory report is, “How is the rate of dissolving sugar affected by changing the temperature of the water, changing the rate of stirring, and changing the size of the crystal?” The independent variable of each laboratory experiment is different, however they are all being changed to get consistent and effective results for one dependent variable. The three independent variables are the temperature of water, rate of stirring and size of the crystal and the dependent variable of the all the experiments is the rate of sugar dissolving. HYPOTHESES Below are the laboratory experiment hypotheses that we have formed as a group to figure out what will happen to the rate of dissolving under…

    Abstract The purpose of this experiment is to determine the relationship between the temperature and pressure of air at constant volume which placed the Jolly’s bulb in water of different temperature. At the constant volume of the air in the Jolly’s bulb, the temperature and pressure of the air are measured and recorded throughout the experiment. The result shows that the pressure of the air in the Jolly’s bulb increases as the temperature rises, and the pressure decreases as the temperature decreases. After plotting the graph manually according to the data obtained from the experiment, it shows that the pressure of air is linearly proportional to the temperature of air at constant volume.…
