    theory of the experiment is that an object needs an amount of heat for it to change a unit mass by 1 degree in temperature. The objectives of the experiment are to determine the specific heat of metal specimens using the method of mixture‚ to measure the equipment properly‚ to carefully measure the temperature of the equipment‚ to be patient while waiting for the output of the experiment and to be precise in computing for the specific heat of the specimen. Theory Blanza‚ J.‚ Guevara‚ C.‚ Morsiquillo

    Thermochemistry Thermochemistry is the study of heat evolved and absorbed during the chemical reactions. The system is the interest of the universe; the surroundings are the rest of the universe in which the exchange of the energy with the system takes place. Both‚ the system and the surroundings make up the universe. Heat flow is the transfer of heat from a warm place to a cooler one. System to surroundings: Surroundings to system:

    Background Information: Heat is energy that transfers from one object to another because of a temperature difference between the objects. Heat is measured in a calorimeter and the units for heat are joules or calories. The calorimeter uses the Law of Conservation of Energy which states that energy is never created or destroyed but is transferred between objects. Temperature is a measure of the average kinetic energy of the particles an object which is different that the heat which is all the energy

    familiar with is called heat while temperature is the measure of a degree of heat or coldness of an object. In everyday life‚ heat or cold is commonly used to explain the degree of temperature of an object. An object that is said to be hot means it has a high temperature. Similarly‚ when an object is said to be cold‚ is means it is has a low temperature.  IMAGE GOES HERE Image Source Why does heat move from our hands to ice cubes and not vice versa? This is due to the heat transfer from a high

    Clausius was the first to formulate the second law in 1850. His statement was that “no machine whose working fluid undergoes a cycle can absorb heat from one system‚ reject heat from another‚ and produce no effect”. Following these came about another statement made by Kelvin and Plank which said “no heat engine whose working fluid undergoes a cycle can absorb heat from one reservoir‚ deliver an equal amount of work and deliver no other effects”. One example of the second law of thermodynamics is when
