    1. 1 Temperature vs Heat (energy) Temperature is a quantity that tells us how warm or cold an object is with respect to some standard It is a measure of the degree of hotness or coldness of a body

    2. 2 Heat Heat is the energy transferred from a body of high temperature to a body of lower temperature. Transfer of heat energy will take place whenever there is a temperature difference between bodies. Transfer of heat will only stop upon Thermal Equilibrium.

    3. 3 Thermal Equilibrium Occurs when energy transfer between two bodies which are at different temperatures results in the two bodies reaching the same temperature.

    4. 4 Transfer of Heat to reach Thermal Equilibrium (i.e. same temperature!)

    5. 5 Transfer of Heat

    6. 6 Methods of Heat Transfer 1) Conduction From hot coffee to the cup to the table 2) Convection From hot coffee to air above 3) Radiation From the side of the cup to the surrounding air

    7. 7 Transfer of Heat

    8. 8 CONDUCTION Heat transmit through a medium from one particle (molecule) to another. No visible movement or flow of material medium. Example: Heat is conducted from one end of rod to another.

    9. 9 How does Conduction Works (Using kinetic theory of matter)? Example: Heat conducted through a rod Particles in the rod nearer to the heat source gets heated up and vibrates more vigorously (Heat ? Kinetic) These particles will eventually collide with the neighbouring particles and transfer the thermal energy. The neighbouring particles will thus get heated up and vibrate more vigorously. This will go on until the thermal energy reached the end of the rod.

    10. 10 Conduction in different medium It can be deduced that if a medium has particles that are closer to one another, the faster will be the rate of conduction. Solid vs Liquid vs Air? Solid is the best conductor followed by liquid and air.

    11. 11 Conduction in solids Metals are better conductors than non-metals (wood, plastic, glass etc) because of the presence of Free Electrons. Free electrons can move from one end of the solid to the other end to pass on the thermal energy in addition to the normal conduction process.
