Specific Heat and Conservation of Energy When energy in the form of heat Q is added to a material‚ the temperature of the material rises. Note that temperature‚ in units of degrees Celsius (°C) or Kelvin (K)‚ is a measure of how hot or cold a substance is‚ while heat‚ in units of joules (J) or calories (cal)‚ is a measure of its thermal energy. 1cal = 4.19J. A measure of the efficiency with which a substance can store this heat energy is known as specific heat capacity‚ or simply the specific heat‚ . The

ANALYSIS On the first part of the experiment which is the determination of specific heat of metals. The obtained value of experimental specific heat of metal of aluminum and copper are 0.2152 calg-℃ and 0.0958 cal g-℃ ‚ respectively. It is a must to work faster in performing this experiment because working in an air-conditioned room greatly affects the result of the temperature. For the temperature values‚ the final temperature of mixture should not increase more than 1 ℃ compare

Heat of Neutralization: Lab Report In part A of this lab I determined the heat capacity of a calorimeter made out of two Styrofoam cups nesting together with a cardboard top containing a hole in the middle. First I placed 50 mL of water in the calorimeter‚ waited five minutes for the water to reach equilibrium‚ and used the computer’s temperature instrument to record the final temperature of the system. Next I heated 50 mL of water in a 250 mL beaker until the water reached 43.1 C (approximately

Introduction- Heat is energy that is warm. Heat energy comes from different energy forms or types like electrical. Heat is also natural‚ from the sun. Heat transforms by reflecting on something and giving it warmth. The temperatures on the coloured cans will vary because they absorb different amounts of heat. According to the particle theory when an object heats up the particles spread out and move more. Aim- The aim of this experiment is to test how colour affects the amount of heat being absorbed

vibrating around‚ the hotter the object feels. We can sidestep this molecular picture by dealing with objects as a whole‚ and treating the energy transfer as the flow of heat‚ rather than kinetic energy transfer among particles. |Specific Heat for Various Materials | |Material |Specific Heat | | |(J/kg C°) | |Water |4186 | |Aluminum |900

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.

Heat of Neutralization for an acid-base reaction Contents: - Abstract - Introduction - Results and Discussions - Conclusion - References Abstract: In the experimental procedure we will measure the heat of neutralization when an acid and base react to form 1 mole of water. This quantity of heat is measured experimentally by allowing the reaction to take place in a thermally insulated Styrofoam cup calorimeter. The heat liberated in the neutralization reaction will

From the experimental data and through its analysis‚ the enthalpy of combustion for the five alcohols were determined; methanol‚ ethanol‚ propanol‚ butanol‚ and pentanol. As the line of best fit in the graph suggests‚ the enthalpy of combustion increased as the sizes of the molecules increased. This was predicted in the hypothesis and proves it to be correct. As seen on the graph‚ the enthalpy of combustion increases from 140kJ/mol for methanol‚ which has the smallest molecular mass‚ to 530kJ/mol
