CALORIMETRY AND HESS’S LAW: FINDING ΔH FOR THE COMBUSTION OF MAGNESIUM MATERIALS: 12 oz. Styrofoam cup with lid‚ thermometer‚ 50-mL and 100-mL graduated cylinders‚ weighing boat‚ 1.0 M HCl‚ 1.0 M NaOH‚ magnesium ribbon‚ magnesium oxide‚ copper wire. PURPOSE: The purpose of this experiment is to determine the enthalpy change for the combustion of magnesium: Mg (s) + ½ O2 (g) → MgO (s) ΔHrxn = ΔH combustion by determining the ΔH values for reactions which can be combined together according

3.1 Metabolic Load: The metabolic activities inside human body constantly create heat and humidity (i.e. perspiration). This heat passes through the body tissues and is finally released to the cabin air. This amount is considered as a heat gain by the cabin air and is called the metabolic load. The metabolic load can be calculated by Qmet = Σ MADU Passengers Where M is the passenger’s metabolic heat production rate. (It is assumed from ISO 8996 based on various criteria for driver: M = 85 W/m2

CHAPTER 1 INTRODUCTION 1.1 What is thermodynamics? Thermodynamics is the science which has evolved from the original investigations in the 19th century into the nature of “heat.” At the time‚ the leading theory of heat was that it was a type of fluid‚ which could flow from a hot body to a colder one when they were brought into contact. We now know that what was then called “heat” is not a fluid‚ but is actually a form of energy – it is the energy associated with the continual‚ random motion of the
