Exams, Over, Thank God.

Actually the exams ended last Friday, but I spent the weekend burying myself under my thick ivory covers. I did great on Calculus, but not so well on Physics. I guess I overthought too much.

A question from our recent Physics II test I mistakenly solved was about finding the ratio between two specific heat with given applied heat, temperature change, and mass of both substances.

The specific heat capacity of a substance or simply specific heat (c), is the amount of heat energy required to raise the temperature of one gram of the substance by one degree (ºC). It can be easily calculated using the Heat Formula q = mc$\Delta T,\; where\; q\; is\; the\; heat\; energy\; gained\; or\; lost\; by\; a\; substance,\; m\; is\; mass\; (in\; grams),\; and \Delta T\; is\; the\; change\; in\; temperature.$

I wasn’t focused enough – I solved it as if the two substances were applied with different heat and therefore came out with an answer of 3:8, whereas the correct response was 1:2.

I couldn’t stop smiling as I went through my Calculus test sheets – I could see through the tricks laid out, and I still had 30 minutes left to go over the whole test a couple of times.
