44. IE • Assume that a tile floor and an oak floor are at the same temperature and are equally thick. Both are cemented to the same subfloor (i.e., their undersides are at the same temperature also).

(a) Compared with the oak floor, the tile floor will conduct heat away from your bare feet (1) faster, (2) at the same rate, (3) slower.

Why?

(b) Calculate the ratio of the heat flow rate of the tile floor to that of the oak.
