Part B Refer to the observations of the test tubes from part A. Determine which metal (or hydrogen)

in each test tube is more reactive. Remember that the less reactive metal (or hydrogen) will

typically end up in pure form as an element, so no reaction will occur if the less reactive metal

(or hydrogen) is the one that begins in pure form.

35. a insulated cylinder of solid gold (k 310 kw/m-k) of radius v2 m and height 5 m is heated at one end until the temperature at each point in the cylinder is given by w(r, y, z) (30 z2)(2-(r2+ y2). determine the rate of heat flow across each horizontal disk given by z 1, z 2, and z 3, identifying which has the greatest rate of heat flow across it.
