Introduction The first law of thermodynamics states that the energy of the universe is constant. Heat is transferred when the atoms of one material vibrate and collide with the atoms of another material‚ thus transferring energy. For this reason‚ heats always travel from hot to cold objects and two objects will reach an equilibrium temperature. Materials and Methods 1. Oven 7. Test Tube 2. Pasco Temperature Probe 8. Stopper 3. Scale 9. Calorimeter 4. Samples of Metals

Canford Heats is situated in the temperate climate‚ where the warmest temperatures are on July and range from 12-22 °C‚ being within the sunniest part of the country‚ whilst coldest temperature is in February‚ from 2 to 8.3 °C. Dominant soil composition is acidic‚ mostly due to the past erosion‚ and is strongly leached (posolised)‚ along with soils predominant in valleys where the waterlogging is present or thicker clay layer which forms peaty gleyed podsolos. These features have created distinct

MEA heat exchanger E-114. This heat exchanger is a counter flow shell and tube heat exchanger and is designed to heat up the rich MEA stream flowing from the CO2 absorber to the stripper. The principle that is applied is heat exchange between cold stream and hot stream which in this case the heat energy is transferred from the lean MEA stream to the rich MEA stream. Apart from this‚ the chemical engineering design for this heat exchanger includes the determination of its dimensions and heat exchange

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

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:

Ten Minutes of Specific Heat Remi Adams East Rowan High School AP Environmental Science Abstract Specific heat and climate were the primary focus of this lab. Specific heat is defined as “the measure of the ability of a substance to change temperature”. The purpose for carrying out this lab was to determine the specific heat/rates of both soil and water‚ and then comparing them. Students also were to relate specific heat to climate. Students were to determine which substance expressed
