UY1: Temperature Scales

(1) The Fahrenheit Scale – Invented by Gabriel Fahrenheit (1686 – 1736) – Between 1708 – 1724, he discovered ways to make high quality liquid-in-glass thermometers and proposed the following fixed points to standardise measurements. Two fixed points: – Melting point of ice: 32°F – Boiling point of water: 212°F   (2) The Celsius Scale – Invented by Anders Celsius …

Heat Capacity

Heat Capacity Heat Capacity, C, of a body is defined as the amount of heat (Q) required to raise its temperature (θ) by one degree, without going through a change of state.  Amount of heat needed to raise the temperature of an object depends on the mass of the object. Heat capacity also depends on the material of the object. …

Internal Energy

Internal Energy Every particle in a body has potential energy, due to their state and position, and, kinetic energy, due to their motion. Collectively, the sum of these energies is called the internal energy of the body. Potential energy of particles in a body tends to be small and does not change very much, a change in internal energy is …

Potential Difference

When a torch bulb is connected to a battery, the torch bulb gets lit. The battery converts chemical energy into electrical energy and is therefore a source of electrical energy. The torch bulb converts electrical energy into heat and light and is therefore a sink of electrical energy. Dissipation of electrical energy between two points (e.g. across torch bulb) in …
