Lab 4: Energy Conservation: Hot Stuff!! The purpose of this experiment is to try to find the original temperature of the hot water in the heater using the 60 degrees C thermometer. Use your 60°C thermometer, and any materials available in your laboratory, to determine the temperature of the water in the coffee pot. During this experiment we calculated the original temperature of a heater after it had been cooled down, and we did this by measuring hot, cold, and warm water, with a thermometer that had tape covering 60 degrees and up. When preformed each of these experiments with each temperature of water, plugging them into the equation (Delta)(Ti – hot – Tf) T Hot x Cp x Mass(Cold) = (Delta)(Tf – Ti – Cold) T Cold x Cp x Mass(Hot)(d …show more content…

#### In this essay, the author

• Explains how they calculated the original temperature of a heater by measuring hot, cold, and warm water, with tape covering 60 degrees and up. the lab gave them the skills to work well in the professional environment and to be conscious of the environment.
• Explains lab 5's 'molecular model building' experiment. the handout provided charts for us to record data on the number of valance electrons present in a molecule.
• Explains the purpose of lab 6: to determine the amount of heat liberated by a particular fuel by measuring the increase of the water temperature earner provided by the fuel.
• Describes how the first week of the experiment was a collaboration of ideas and planning that helped develop skills in leadership and problem solving.
• Explains the main purpose of the experiment, which was aimed at comparing authentic and sample ions.
• Explains the formulas used to measure the amount of different ions in a fertilizer sample by counting to preform tests. the begging of the experiment requested that the percentage of so4 be found.
• Describes how the energy content of fuels experiment focused mainly on the amount of heat liberated by a particular fuel contained in alcohol lamps, which stored absolute ethanol, butanol or kerosene.

During week 1 of this experiment, we recorded common components of fertilizers and then went on to find the chemical formulas involved in creating them. The second week we began the process of comparing three authentic ions we had established in the first week to ion samples to discover other properties they might contain. We decided to discover these different ingredients by preforming a serious of tests, which included placing 0.2g solid of both the authentic and the sample fertilizer separately, in order to establish a constant, and dissolved the fertilizer in 20 mL of water, then checked to see if Mg was present in the sample solution. By setting up a constant and preforming a methodical experiment all on the samples given, we demonstrated the ability to correctly establish and preform an experiment and solve the problem at hand, which was distinguishing the contents of the authentic …show more content…

We gauged the amount of mass that the fuel lost when raising the temperature of water 20 degrees C. Throughout the experiment we constantly worked with chemicals, boiling water, and liters, turning the Bunsen burners on and off. Because of this, each member of our group were carefully to wear goggles, gloves, a lab coat, and closed toed shoes, with pants down to the ankles. We also cautiously recalled the safety quiz with the locations for the shower and eye flusher in order to make sure we were prepared in case we required their use. Learning to remember these skills grew our knowledge and helped us be cautious for labs to come when working with dangerous
