One mole is defined as the amount of substance that contains as many elementary entities as there are atoms in 12g of carbon-12. This number is called the Avogadro constant, NA, and has been measured as 6.02 × 1023. The kinetic theory of gases is a model used to...
The specific heat capacity of a substance is how much energy is needed to raise the temperature of 1kg of that substance by 1° You can determine the specific heat capacity of substances in the laboratory: For a metal, use an electric heater to heat a metal cylinder....
Bodies are in thermal equilibrium if there is no net flow of energy. This happens when they are at the same temperature. Thermal energy is always transferred from regions of higher temperature to regions of lower temperature. According to the zeroth law of...
According to the simple kinetic model, solids, liquids and gases are made up of tiny moving or vibrating particles. solid liquid Gas are held tightly and packed fairly close together - they are strongly attracted to each other o are in fixed positions but they do...
