do-dodec--ca-ca-----n-o-o-....screw it, I'll have some lauric acid please :D

Sorry for the late lab post, we did a lab on heating and cooling curves of pure substances.(we used lauric acid). The point of this lab is to determine the freezing and melting points of pure substances.

To start, we got our goggles and the appropriate equipment needed. We began with cooling our substance. We lowered a test tube with a thermometer into a beaker filled with cool water and observed and recorded the temperature at each 30 s interval until the temperature reached 25 degrees Celsius. 

For the heating process, we placed the beaker on a hot plate and lowered the test tube into it. We observed and recorded the temperature in 30 s intervals until it reached around 55 degrees Celsius.   Once we're finished, we cleaned up everything and started our lab reports. 

again..sorry for the latelate late latelatelate lab day post.
