Sameera Raziuddin Latent Heat of Fusion April 11‚ 2011 Abstract: A calorimeter‚ water at room temperature‚ ice‚ and a Pasco GLS Explorer were used in combination with a known value of the latent heat of fusion to create and carry out an experiment to determine the mass of an unknown amount of ice. Using the formula for latent heat of fusion‚ the mass of the ice was calculated to be 45.76g. The error of the carried out experiment was calculated to be 20.06%. Introduction:

Malaysia Solution Essay Braeden Alexanderson Year 10 The word Asylum seekers is not an unknown topic to Australia. The Asylum seekers or ‘boat people’ have been contentious issue in Australian politics for many years. According to Google dictionary an Asylum seeker is: “a person who has left their home country as a political refugee and is seeking asylum in another.”The big debate surrounding the area of asylum seekers is how to moderate the amount of boat people coming into Australia.

Civil Engineering Department‚ College of Engineering‚ Adamson University Abstract The purpose of this experiment is to determine the Latent Heat of Fusion of ice. In this experiment‚ the heat of fusion of ice will be determined by using the method of mixtures (Quantity of heat lost = Quantity of heat gained). Introduction When a substance changes phase

1. INTRODUCTION An engine is a device which transforms one form of energy into another form. Most of the engines convert thermal engine to mechanical work and therefore they are called heat engine. Heat engine can be broadly classified into two types. i. Internal combustion engine ii. External combustion engine 1.1 CLASSIFICATION OF INTERNAL COMBUSTION ENGINE:- This type of engine is again classified into two types. i. Rotary ii. Reciprocating The reciprocating engine is a highly complex

Heat of Neutralization Lab Objective: The objective of this lab was to measure‚ using a calorimeter‚ the energy changes accompanying neutralization reactions. Background: Chemical changes are always accompanied by a change in energy‚ typically as heat. If the reaction releases heat (ΔH < 0) then the reaction is exothermic. If the reaction absorbs heat (ΔH > 0) then the reaction is endothermic. The quantity of heat is measured experimentally by having the reaction take place in an insulated container called a

of the metal was determined by the heat energy calculations. The heat capacity that was found matched closely to that of the lead. There were several possible sources of error that could be found throughout the lab. Some of the main errors as seen in question 7 that could have affected the results of the lab were the amount of water transferred with the hot metal‚ the metal cooling off as it was transferred from the calorimeter‚ the calorimeter lost heat to the surroundings as it was stirred

radiation is one of the three ways in which heat is transferred. In convection‚ heat can be exchanged from one fluid to another. In this experiment‚ a heated plate is in contact with air inside a rectangular cross section duct. The air is heated by conduction from the heated plate. The density of the air decreases as it is heated and this makes the warm air rise. Colder air‚ which in turn is less dense‚ then replaces the warmer air‚ which has risen. The plate then heats this colder air‚ which will eventually

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
