Alkanols Aim: To determine which alkanols has higher heat combustion Hypothesis: The alkanols with the longer carbon chain will a higher heat combustion Background Information: Heat combustion can be calculated by using various formulas. By using ΔH= -mcΔT‚ we can gather the amount of heat released. Since the experiment is exothermic‚ ΔH will have a negative value. By dividing the total amount by 1000‚ the units changes into KJ. Divide the total KJ of heat by the amount of fuel used(in grams) which gives

KAYS§ (Received 10 March 1964) Abstract-An analysis of heat transfer in a concentric circular tube annulus with an arbitrarily prescribed heat flux around the periphery of either wall‚ or both walls‚ is presented. Solutions have been obtained for the hydrodynamically and thermally fully developed condition for constant heat rate per unit of tube length‚ for

Title: Specific Heat of Solids II. Object: To determine the specific heat capacity of solids by methods of mixtures. III. Theory: When to or more substances at different temperatures are mixed‚ heat will flow from the substance of higher temperature to the substance of lower temperature. The heat flow will continue until equilibrium in temperature is reached. From the Law of Conservation of Energy‚ whatever amount of heat is lost by the hot substance must be equal to the heat gained by the cold

Specific Heat of a Metal Post-Lab I. Purpose The purpose of this lab is to determine the specific heat of an unknown metal. II. Safety Wear goggles and lab apron at all times. Use caution when boiling water. Do not pick up hot beaker or hot metal with hands. Use tongs. III. Pre-Lab Questions 1. A 12.5 g metal is raised to 100C in boiling water. It is put into 82.8 g of water at 22.4C‚ and the water rises to 28.6C. Recalling that the specific heat of water is 4.18J/gC‚ use the equation above
