In order to measure the heats of reactions, add the reactants into the calorimeter and measure the difference between the initial and final temperature. The temperature difference helps us calculate the heat released or absorbed by the reaction. The equation for calorimetry is q=mc(ΔT). ΔT is the temperature change, m is the mass, c is the specific heat capacity of the solution, and q is the heat transfer. Given that the experiment is operated under constant pressure in the lab, the temperature change is due to the enthalpy of the reaction, therefore the heat of the reaction can be calculated.

In this lab experiment our main focus was to get skillful in using tools such as the metric ruler, balances, thermometer, and graduated cylinder to capture measurements of length, mass, temperature and volume. Additionally, this lab helped us to become more familiar with the uncertainty of measurements, as well as becoming efficient with rounding our measurements to the correct numbers of significant figures. Our results are measured consistently with rounding to the closest answer we could possibly acquire as the data can tell you.

The lab uses the measurements of a wooden dowel in length and diameter to collect data in order to interpret data in report form. The data is used to produce statistical data and how to correctly present it. A ruler and micrometer were used to measure the dimensions. Spreadsheets are then constructed in order to generate standard deviation, mean, median, mode, frequency, as well as variation of length, diameter, volume, and cross sectional area of the

Materials: Two-500 ml beaker, a source for warm/hot water and room temperature water, stirring rods, a container full of salt, cup for the salt, a scale, heat pads, a thermometer, safety googles and aprons. Procedure: 1. A beaker was filled with 100 ml of room temperature of water that had a temperature of 30 degrees Celsius measured by a thermometer.

2.2 Compare + contrast the Kelvin, Fahrenheit, and Celsius temperature scales and be able to convert values between scales.

To describe the variable “temperature”, we are basically using a thermometer, soda, cups, and a board. We are basically changing the temperature .The temperature and the soda is basically our main focus. What is being learned is how the temperature changes when you put the thermometer in the cups where the soda carbonation is in. After, we take notes and record our information on the project board.

Collect all equipment needed for the practical, Thermometer, boiling tube, 2 substances, distilled water, measuring cylinder, weighing boat to measure substance, Test tube holders, goggles, lab coat, spatula, balance scales. 2.) From the equipment you have collected set up the equipment. Measure 20ml of water in the measuring cylinder and transfer the 20ml of water in the boiling tube. After that measure the start temperature of the water using a thermometer and read the meniscus at eye level accurately.

Temperature is a measure of the average kinetic energy of the particles in a body. Temperature can be understood by recognizing that a hot object contains more thermal energy than a cold object. The amount of thermal energy in a substance is affected by the amount of particles that are in it. Temperature is independent of number of particles in

Our thermos was quite effective in insulating hot water, as the graph was very flat. This indicates that as time passed, the temperature of the hot water dropped very little, resembling an exponential decay graph. Trial one and trial two presented very similar results and a constant rate of change, which further reinforces the effectiveness of the thermos. The second trial basically presented identical data to the first trial, which can be seen on the graph as the two lines are merged together. The lumps in the graph for the control were resulted from the accidental moving of the temperature probe or the occasionally currents of air flowing across the cup,

Pablo S. - Pablo’s developing skills in english can cause confusion when discussing and learning thermodynamic principles. The complex vocabulary can confuse Pablo. In order to ensure that Pablo learns from this experiment, I will provide Pablo a procedure and have a meeting with him to discuss any terms or phrases within the procedure that cause some confusion. During this meeting, Pablo will record the discussion points in his lab notebook. This will ensure that when Pablo is completing the lab he will have access to the information from our conversation on the confusing terms associated with the experiment. This information will hopefully aid Pablo during the experiment. If not, Pablo can ask me questions during the experiment.

The setup of this experiment was fairly easy. Firstly, the temperature probe and the microphone were fixed to a ring stand and connected to the labquest; the labquest was itself connected to the CPU. Photo 1. From here, the logger Pro was launched. The temperature reading was recorded (20.7 o C in our case) and the microphone background reading was noted. As this point, the use of the temperature probe was over, and so it was disconnected from the labquest.
