I. IntroductionA. Purpose the purpose of this experiment was to determine if the distance between matter set up the time it takes for the matter to reach thermal symmetry.B. Hypothesis If the distance between the matter is decreased then the time it takes for the matter to reach thermal equilibrium will decrease.C. Science concepts Temperature- measure of the motion of moleculesThermal equilibrium- when two pieces of matter are the same temperatureKinetic energy- energy of motionHeat- energy that flows from matter of a higher temperature to matter of a lower temperatureIn the experiment the time it took for matter to reach thermal equilibrium was measured. The temperature of the water was measured every xxx seconds. The heat was transferred from the hot water, into the air, then to the cold water. When the water reached thermal equilibrium the average kinetic energy per molecule was the same for all the water.II physical processThe materials used were- 125ml flask200ml cold wat er200ml beaker2 lab probes125ml hot waterlogger pro1.first the lab probes were plugged into the lab pro2.the lab pro was connected to the USB port3.the computer was turned on and logger pro was opened4.the flask was alter with 125ml of hot water5.the beaker was filled with 200ml of cold water6.the flask and beaker were placed 20cm apart7.the temperature was measured every 30 seconds until the hot and cold water reached thermal equilibriumIII. Results and ConclusionsA. Experimental data The results of the experiment indicate that the farther apart the matter is the longer it takes to reach thermal equilibrium. The wretched water took only sixteen minutes while the non touching water in about the same amount of time was 41.6 degrees from reaching thermal equilibrium.B. Graphs and Tables see attachedC. Evaluate Prediction/Hypothesis The results of the experiment apply the hypothesis. The hypothesis stated that the greater the distance between the water the greater the amount of tim e it takes to reach thermal equilibrium.IV consultation and SummeryA. Extension Some causes of experimental error may stool been if the computer failed and a manual thermometer had to be used some seconds could have been lost. This could have been fixed by using a manual thermometer the whole time or starting over if the computer failed. Another possible cause of experimental error could have been if the probe was being moved while the temperature was being measured.
