I. IntroductionA. Purpose the purpose of this experiment was to instruct if the distance between affair effects the time it takes for the matter to grasp thermal counterbalance.B. Hypothesis If the distance between the matter is decreased thence the time it takes for the matter to reach thermal equilibrium will decrease.C. accomplishment concepts Temperature- measure of the motion of moleculesThermal equilibrium- when two pieces of matter are the equivalent temperatureKinetic energy- energy of motionHeat- energy that flows from matter of a higher(prenominal) 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 piss was measured every cardinal seconds. The heat was transferred from the hot peeing, 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 ProcedureThe materials u sed were- 125ml flask200ml cold water200ml beaker2 lab probes125ml hot waterlogger pro1.first the lab probes were out of use(p) into the lab pro2.the lab pro was connected to the USB port3.the estimator 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 further apart the matter is the longer it takes to reach thermal equilibrium. The touching water took only sixteen minutes while the non touching water in about the same add of time was 41.6 degrees from reaching thermal equilibrium.B. Graphs and Tables experience attachedC. Evaluate Prediction/Hypothesis The results of the experiment support the possibility. The hypothesis stated that the greater the dis tance between the water the greater the amount of time it takes to reach thermal equilibrium.IV flank and SummeryA. Extension Some causes of data-based error may have been if the computer failed and a manual thermometer had to be used some seconds could have been lost. This could have been meliorate 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 beingness moved while the temperature was being measured.
