Lesson question: how can you determine the specific heat of a
metal using a calorimeter?
to do this computation for each of the four metals, you needed
several measurements.
of the metal and the water inside
. first, you measured the
the calorimeter
the metal and added it to water in the
. then, you
calorimeter
12.45g
after heat transferred from the metal to the water, you measured the
of both materials.

intro

Solid tin exists in two forms: white and gray. for the transformation sn(s, white) → sn(s, gray) the enthalpy change is -2.1 kj/mol and the entropy change is -7.4 j/(mol*k). a. calculate the gibbs free energy change for the conversion of 1.00 mol white tin to gray tin at -30℃. b. will white tin convert spontaneously to gray tin at -30℃? c. at what temperature are white and gray tin thermodynamically equivalent at a pressure of 1 atm?
