    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

    The Calorimeters Calorimeters are a device that can measure the heat that comes from burning an item. Simple Calorimeter A simple calorimeter is used to detect the enthalpy change when a fuel is burned. The fuel is burnt to heat a specific mass of water and then measure its rise in temperature. The word calorimeter comes from the Latin phrase calor which means heat. A simple calorimeter just consists of a thermometer attached to a metal container full of water suspended above a combustion chamber

    The heating of brown beans‚ red cabbage‚ liver sausage and brussel sprouts was done in a water bath of 82.5°C. As can be seen in figure 1 the brussel sprouts heated up the quickest and took 11 minutes to come to a 77.5°C temperature or a 5°C lower temperature than the max. The other three heated up similarly with red cabbage taking 38 minutes‚ brown beans 42 minutes and the liver sausage taking the longest with 45 minutes. Water was added to the brussel sprouts and that did have an effect on the
