 Today we're going to do a lab called the specific heat of a metal. We're actually going to determine the specific heat experimentally of two different metals. I will start now by taking the first metal and weighing it. And now I will place the metal in the boiling water. And now we're going to mask the coffee cup colorimeter. Now we will add 50 mils of water to the coffee cup colorimeter. And we will proceed to weigh it once again with the water in it. Now that we have masked the coffee cup colorimeter and the water we're going to hook up the temperature probe and go link to the laptop. I hook up the temperature probe to the go link and then I use the USB connection to hook up the go link to the laptop. We're going to open up logger pro and as you can see down on the lower left hand corner the logger pro is already recognized the fact that we have a temperature probe hooked up plus you know that it has been recognized because the light has gone from red to green on the go link. And using the instructions that are in the procedure we're just going to set up logger pro for this experiment. And as the procedure indicates first we go to experiment then we go to data collection and we set up the mode of data collection as time base it's already there but we have to indicate that we're going to record for 300 seconds and we're going to record one sample one data point every five seconds and with this we're done then we're going to double click on the temperature column and we're going to indicate that we want a precision of two okay and now we're ready to go. So now I will put the temperature probe into the colorimeter coffee cup colorimeter and I will start collecting data and the first set of data will be the temperature of the water inside the colorimeter. I will wait the temperature to settle down to a steady value and now I will remove the metal from the boiling water shake as much water off as I can place it into the coffee cup colorimeter and I will start stirring and the temperature now the water is increasing and I'll keep stirring until eventually it levels off to a steady value of temperature. Well the temperature now has been dropping for a while you a maximum was reached so I will land the measurement of the temperature at this point. Okay so now we need to mess the second metal. Essentially we need to repeat the same process that we done for the first one. We will add 50 mils of water to the coffee cup colorimeter. We're going to mess the cup and water again for the second metal. I do not need to mess the empty dry cup because I already have done that. Okay so now I already have Luggerpro set up ready to go and I will put the metal in the boiling water and wait for five minutes. Okay so now that the metal has been in the water for boiling water for at least five minutes we're going to start collecting data and we'll start once again by measuring, taking measurements of the initial water temperature inside the colorimeter and I will wait to add the metal once I have a steady temperature being recorded of the water in the colorimeter. Okay looks like a heavy steady temperature so now I will pull the second metal out shake as much water off it as I can and I'll make sure that when I put it in I knock the metal over so that it's fully submerged in the water. In other words none of the metal is above the water line and I'll start recording temperature as I've done before and I will keep recording temperature until I see that I have a steady value and also I would prefer if possible to see the value of the temperature drop. Well the temperature now has been dropping for a while in other words I'm past the highest peak and so I'm going to add the collection of the data. Now it is your job to access the logger profiles available to you and collect the necessary data. After you've done that you can use the data to do the necessary calculation calculations and turn in your report.
