    Finding a Material's Specific Heat Capacity Skill A Aim: The aim is to accurately find the specific heat capacity of a material given a certain mass of that material and other experimental equipment. The specific heat capacity of a substance is the heat energy required to raise one kilogram of the material by one Kelvin or one degree centigrade - it is usually measured in J kg-1 K-1. The experimental technique and results will be analysed. The purpose is to be able to conclude the

    In part one of this calorimetry experiment, the heat gained by the system, the sausage, was lost by the surroundings, the water. This relates to the 1st Law of Thermodynamics that states “energy can neither be created nor destroyed”. In parts two and three of this experiment, the heat generated by the reaction was transferred to the solution. The first the first calculation I had to perform was finding the specific heat capacity of the sausage by using the formula, m_water C_(p,water) 〖ΔT〗_water+m_sausage

    Specific heat capacity refers to the amount of energy that is required to change the temperature of 1 kg of a substance by 1°C. With that in mind, there are countless practical applications that exist, both in general life and in the workplace. For instance, knowing the specific heat capacity of a steel pan decreases the probability of burning the kitchen utensil. In a controlled environment, such as an engine production plant, the specific heat capacity of numerous metals and plastics can be utilized

    Aim: To determine the specific heat capacity of brass using calorimetry, the understanding of the relationship between heat and temperature and the concept of heat transfer, using the equation; Q=mc∆T. Also to evaluate the data collected by comparing the experimental value to the accepted value using analytical skills. Method: • We heated up a brass weight by immersing it into boiling water for a while in order to assure that the metal’s temperature was the same as of the water. • We then placed

    ecosystems to survive. Further, because ice floats, it is able to prevent the loss of heat from bodies of water, providing insulation for aquatic organisms. The freezing of water and melting of ice also ease the transition between seasons for organisms. When water solidifies into ice or snow, the heat released warms the surrounding air, helping to temper the autumn. Similarly, during the spring, melting ice absorbs heat, tempering the transition into the warmer season.

    69 PENTAN-1-OL 0.55 HEXAN-1-OL 0.52 Following the gathering of results, the enthalpy change of combustion of the alcohols was calculated using the equation from page 2: Energy Transferred = Mass of water x Temperature rise x specific heat capacity (4.17) Now to calculate the enthalpy change of combustion, the following steps are taken: 1.) Energy per gram = Energy Transferred ÷ Average mass change of alcohol 2.) Energy per mole = Energy per gram x Molecular mass

    Experiment 5 Calorimetry and Specific Heat Lab Partners:_______________________________ February 16th 2017 By: Amanda Luna 1. Abstract The objective of this experiment was to identify a metal based on its specific heat using calorimetry. The unknown metals specific heat was measured in two different settings, room temperature water and cold water. Using two different temperatures of water would prove that the specific heat remained constant. The heated metal was placed into the two different water
