When а hоt оbject cоols, heаt flow occurs into the surroundings, аnd there is a change in entropy, in both the object and in the surroundings. Suppose 100 kJ of heat flow occurs from a hot iron bar at 500 °C to the surroundings, what are the changes in entropy for the bar and for the surroundings?  Assume room temperature (25°C) for the surroundings and use the equation ΔS = q / T. Use the starting temperatures of the iron bar and the surroundings for T in your calculations. Give your answers in units of J/K, to the nearest whole number (we will not use J/mol.K in this case because we are not dealing with 1 mole of anything). K = °C + 273
