A container that acts as a perfect insulator contains two compartments, one containing hot gas and the other cool gas as illustrated in the diagram below. The wall separating the two gases contains a heat conducting material that allows heat to pass from the hot gas to the cool gas. hot gas cool gas perfect insulator The graph below describes the flow of heat through the heat conducting material. heat energy (kJ) 8.0 6.0 4.0 2.0 0.0 0.0 2.0 4.0 6.0 8.0 time (s) a) What is the rate of heat transfer that occurs in the first 2 seconds. b) How many seconds does it take for thermal equilibrium to occur. The heat conductor has a cross sectional area of 2.00 m² and a thickness of 20.0 cm. At the 1.0 second mark, the temperature of the hot gas is 350.0 K and the temperature of the cool gas is 300.0 K. c) What is the thermal conductivity of the new heat conducting material? heat conductor
