  • Absolute Temperature Essay

    1005 Words  | 5 Pages

    A temperature is an objective comparative measure of hot or cold. It is measured by a thermometer, which may work through the bulk behavior of a thermometric material, detection of thermal radiation, or particle kinetic energy. Several scales and units exist for measuring temperature, the most common being Celsius (denoted °C; formerly called centigrade), Fahrenheit (denoted °F), and, especially in science, Kelvin (denoted K). The coldest theoretical temperature is absolute zero, at which the thermal

    measuring the heat transfer with the surrounding. It is derived from the word calor in Latin, which means the heat and the pressure. Calorimeter is the device used in the calorimetry science to measure the quantity of heat transported from or to an object. Heat is the transfer of thermal energy between two bodies that differs in temperature (Mc Graw Hill Education). Calorimeter helped many generations to measure the quantity of heat using different types of devices; also they followed a specific procedure

    the solution when it reacts with 25cm3 Copper II Sulphate. Theory: Specific heat capacity is the amount of energy needed to raise the temperature of one gram of a substance by 1 degree Celsius. Different materials absorb different amount of heat when their temperature rises by one degree Celsius. Therefore, every material has a different specific heat capacity. Metals usually heat up very easily because they have a low specific heat. Equations Mn(s) + CuSO4 (aq)  MnSO4 (aq) + Cu (s) Fe(s) + CuSO4

  • Summary: Latent Heat Of Fusion

    982 Words  | 4 Pages

    is the changes of substances or molecule from a solid state to a liquid state. Another words for melting are latent heat of fusion. When heat is transferred, the temperature will rise or fall typically. But there are also cases that heat does not change at all when heat is transferred. So this type of heat is called latent heat (Figura and Teixeira, 2007). So latent heat of fusion is also the enthalpy of fusion of a substances and molecule, or in another words is the changes of enthalpy of a substances

    What can one individual do to change their lifestyle and help the environment? It doesn’t seem like one person would be enough. How about hundred or millions of people? Seems possible now. Doesn’t it? How about going vegan or cutting down on the portion of meat per week? Even changing your diet to organic? It sounds challenging but not impossible. By doing either one you can help make a difference to our environment. Most of the animals we eat are not being raised naturally because workers are being
