Conclusion States of Water Aim to investigate the changes of state of water using the data logging technology to monitor the temperature changes occurring during the changes of state of water Equipment crushed ice with salt crushed ice without salt two 1L. beakers two stirrer hot plates two -15 - 100oC thermistors computer, TCSLOG program datalogger, two thermisters, cable connecting the datalogger to the computer Procedure Part A crush ice in a teatowel with the flat of a hammer put half the crushed ice in a 1L beaker and stir in the salt put in the other half of the ice in the other 1L beaker place small plastic jackets around the thermisters and plug them into the zero and one inputs of the datalogger setup the computer and TCSLOG program to read the two thermisters(this should be clear from the prievous experiments) setup the datalogger Part B place one thermister in each beaker Use the datalogger to record the two temperatures every 30 seconds for 1 hour save the data to a file called icetemp.txt plot the temperatures to a chart as they are recorded place each beaker on a hot plate set to low heat with a stirrer inside and begin to monitor the temperature once the water has been turning into stream for a while you can stop the experiment open the data into a spreadsheet and plot the two sets of temperature data against time?
