What are the two reasons why a computer should be used rather than manual methods?

Well, if I understand your question, a computer could make faster calculations and keep more accurate measure of both temperature and elapsed time with all components connected to one unit. Are you measuring BTU loss? You probably already know but I have to say it anyway. 1 BTU is the amount of energy it takes to raise, or in this case lower, 1 lb. of liquid one degree F.. British Thermal Unit.

Because the teacher is stupid! Manual data collection has worked for centuries and it's what modern science is built on.
If I had to them what they want to hear, I would say that it reduces errors caused by incorrectly reading the thermometer and collects data faster and aids in displaying the data in a program like Excel. BUT...
If you can't spot an error on paper, you surely won't spot it in the computer, and setting up a computer to measure temp takes more time than reading a thermometer. And if you can't correctly read a thermometer and use a stopwatch, are you really going to understand how the computer is taking measurements? How will you know if your data is valid?

--Computers can store all the changes happening throught the experiment. so the result at any instant/stage of the experiment can be found, unlike manual methods
--Since the error rate is very less compared to manual methods, the results will be accurately & efficiently calculated.. (reliable also)
