In this lab‚ we will measure the heat of combustion‚ or calorimetry‚ of a candle and compare the found quantity with known values for other hydrocarbons. The calorific value is the total thermal energy released when a substance goes through complete combustion with oxygen. In order to achieve the purpose of this lab‚ we must first determine the mass of the tea candle. Then‚ we will determine our room temperature‚ measure about 100 mL of chilled water‚ and then pour the water into the given empty

COST-VOLUME PROFIT (CVP) ANALYSIS This is a technique used for planning short-term run profits by finding the relationship between profits and factors that influence profits. The following factors are taken to be influencing profits:- • Selling price • Variable cost of production • Fixed costs • Activity level (production and sales units) Profit planning is based on break-even analysis and can be worked out using either; a) Algebraic method b) Contribution method c) Break-even

model is based upon an energy analysis that takes into account all the modes of energy loss (L) from the body‚ including: the convection and radiant heat loss from the outer surface of the clothing‚ the heat loss by water vapour diffusion through the skin‚ the heat loss by evaporation of sweat from the skin surface‚ the latent and dry respiration heat loss and the heat transfer from the skin to the outer surface of the clothing. The model assumes that the person is thermally at steady state with his
