Rearranging gives Heat and Temperature Change: Specific Heat Capacity Q = mc T 4186 J = 1 kcal Ex: If 15 kcal of heat are added to 5.0 kg of silver‚ by how much will its temperature rise? Ex: An aluminum cup having a mass of 250.0 g is filled with 50.0 g of water. The initial temperature of the cup and water is 25.0 °C. A 75.0-g piece of iron initially at 350.0 °C is dropped into the water. What is the final equilibrium temperature of the system assuming that no heat is lost to the

FORMAL REPORT ON HEAT CAPACITY RATIOS OF GASES ABSTRACT This report discusses an investigation of the heat capacities of Helium‚ Nitrogen‚ and Carbon Dioxide. To accurately determine experimental values for the heat capacity of each gas‚ the heat capacity ratio was calculated from measurements of the speed of sound in each gas. An apparatus designed to measure the wavelength and frequency of sound waves in each gas was used to determine the speed of sound as a frequency was passed through each

The Spratly Island The Spratly Islands are a group of more than 750 reefs‚[2] islets‚ atolls‚ cays and islands in the South China Sea. The archipelago lies off the coasts of the Philippines and Malaysia (Sabah)‚ about one third of the way from there to southern Vietnam. They contain less than four square kilometers of land area spread over more than 425‚000 square kilometers of sea. The Spratlys are one of three archipelagos of the South China Sea which comprise more than 30‚000 islands and reefs and

Heat of Mixing: Ethanol and Water Abstract The temperature change when known amounts of water and ethanol were mixed was determined to see the enthalpy change in an isothermal and isobaric environment. Agreeable data was found compared to similar experiments. As the mole fraction increased of the solution so did the enthalpy until a certain limit of about 0.32. Since water’s structure and unique properties affect many aspects of a solution‚ the solutions enthalpy’s decreased at a certain time

Rural Khmer house Despite indoor and outdoor temperatures of 36°C and up to 80% relative humidity the old rural Khmer houses are very comfortable‚ both at ground level and on the upper floor. In spite of the absence of electric or mechanical air conditioning‚ a draught-free environment appears to be attained simply by means of natural ventilation. Typically‚ rural Khmer houses are rectangular two-storey buildings‚ varying in size from four by six metres to about six by ten metres. The basic

Understand and observe the concept of Heat Transfer‚ by measuring the temperature distribution for steady state conduction of energy through a specific efficient unit. • Understand the Fourier Law of heat conduction and the usage of its equation in determining the rate of heat flow via solid materials. II. Theory : The Fourier Rate Equation: When a plane section of ∆x and a constant area A maintains a temperature difference ∆T‚ then the heat transfer rate per unit time by conduction

Since the Miami Heat have won their second franchise championship there has been a lot of speculation on the next moves the organization as far as the who will be on next years roster. Ray Allen‚ a future hall of famer‚ is a highly sought after 3-point sharpshooter who is an unrestricted free agent. There has been much controversy in regards to what team will be a best fit for the 37-year-old veteran. According to a blogger on the Bleacher Report he feels that it would be sacrilegious and cowardly
