The quantity of energy Q transferred by heat conduction through an insulating pad in time interval At is described by Q/At= KAAT/d, where K is the thermal conductivity of the material, A is the face area of the pad (perpendicular to the direction of heat flow), AT is the difference in temperature across the pad, and dis the thickness of the pad. In one trial to test material as lining for sleeping bags, 86.0 J of heat is transferred through a 3.40-cm-thick pad when the temperature on one side is 37.0C and on the other side is 2.00C. In a trial of the same duration with the same temperatures, how much heat will be transferred when more of the material is added to form a pad with the same face area and total thickness 9.81 cm?
