Homework Help: chemistry

Posted by dan on Sunday, June 21, 2009 at 8:22pm.

what are some source errors in my experiment? determine absolute zero.

We attached a capillary to a ruler with a thermometer.

placed it in water and heated.

I recorded and my partner did the readings.

source errors:
-partner didn't stir the water before he took the readings. Failure to heat the water uniformly
-partner didn't understand how to read the capillary. In the middle of our calculations he switched.
-Capillary was a different temp than the water. It was not standardized.
-uncalibrated thermometer
-capillary had to stick out of the water...air temp is different from water.


any more ?
