Heat and Temperature

  1. 1. Temperature • It is the measure of average kinetic energy of the particles in a body. Kinetic Molecular Theory of Matter “All particles of matter are in constant motion.” • Temperature is fundamental quantity of any matter. • Units such as Fahrenheit, Celsius/ Centigrade and Kelvin are used to quantify temperature.
  2. 2. Thermometer • It is a device used to measure temperature.
  3. 3. Fahrenheit • It was formulated by Daniel Fahrenheit based on his experiment using a mercuric thermometer and ice-salt solution.
  4. 4. Celsius • It was invented by Anders Celsius using pure water.
  5. 5. Kelvin • William Thomson, also known as Lord Kelvin devised the absolute zero temperature scale. K = 273.15 °C
  6. 6. Internal Energy • It may seem that the glass-water system has zero energy. But in the microscopic level, the molecules are in constant motion(kinetic energy) and attractive forces between molecules(potential energy). • The combination of motion an attractive energy of the molecules gives the internal energy of an object.
  7. 7. Which has the highest internal energy? 90°C 90°C
  8. 8. Which has the highest internal energy? 90°C 90°C
  9. 9. Which has the highest internal energy? 90°C 100°C
  10. 10. Which has the highest internal energy? 100°C 90°C
  11. 11. Which has the highest internal energy? 100°C 50°C
  12. 12. Thermal Equilibrium • It is a condition when bodies in a system cease to transfer heat and is manifested by a single temperature.
  13. 13. Heat • It is a form of energy not inherent in a body. Its presence depends on the difference in temperatures of two bodies in contact. • The transfer of heat is a natural process and will only stop if both bodies possess the same temperature. A B
  14. 14. Heat • It is a form of energy not inherent in a body. Its presence depends on the difference in temperatures of two bodies in contact. • The transfer of heat is a natural process and will only stop if both bodies possess the same temperature. A B
