The power pack was connected to and outlet but I made sure that I connected the wires to the dc slot in the power pack. The mass could have been 2kg as the teacher told us the metals were made to be exactly 1kg yet no one checked. I doubt this though as the metals felt more around 1kg than 2kg...

During class the prof just said that we would have something to go home and think about, he didnt want to tell us (although I doubt he knew). A mistake in the procedure would make the most sentence, yet...

Thanks anyway though. :) Further notes: The top surface was not insulated, yet it didn't feel warm. I doubt that it was the profs first time.
