If the answer is in scientific notation, please convert it to decimal!

Samples A and B are at different initial temperatures when they are placed in a thermally insulated container and allowed to come to thermal equilibrium. Figure (a) gives their temperatures T versus time t. Sample A has a mass of 5.52 kg; sample B has a mass of 1.32 kg. Figure (b) is a general plot for the material of sample B. It shows the temperature change AT that the material undergoes when energy is transferred to it as heat Q. The change AT is plotted versus the energy Q per unit mass of the material, and the scale of the vertical axis is set by ATs = 3.90 .C. What is the specific heat of sample A? 100 AT, A T(C) 60 AT (Co) B 20 10 20 0 8 16 t (min) Q/m (kJ/kg) (a) (b) Number i Units K Hint Co J /K Save for Later mol J/kg.K Attempts: 0 of 1 used Submit Answer J/mol.K KJ/kg kg/mole /Co or (Co)~-1 Co/s J/K.S J/mol J/K.m
