Material time to reach equilibrium a 5 minutes b 30 minutes c 110 minutes in an experiment, a thin sheet of material a, b, or c was used to divide two objects of different temperature. in each trial, the conditions were identical except for the material of the thin sheet. the data table shows the times in which the objects reached thermal equilibrium. which material, if any, is the best thermal insulator? all three are equal insulators. material b
material a
material c
