Kinetic Model of an Ideal Gas Gas Pressure A gas is made of a large number of particles Gas particles have mass and move randomly at high speeds Pressure in a gas is due to the collisions of the ga...
Ideal Gas Equation Avogadro's Law Avogadro's Law states: For a gas at constant temperature and pressure, the number of moles n is directly proportional to the volume V of the gas This can be expres...
Ideal Gas Laws Boyle's Law Boyle's Law states: For a fixed mass of gas at a constant temperature, the pressure p is inversely proportional to the volume V This can be expressed in equation form as:...
Investigating Thermal Energy Estimating the Specific Heat Capacity of a Metal Aim of the Experiment The aim of the experiment is to determine the specific heat capacity of a metal block Variables ...
Phase Change A phase change happens whenever matter changes its state During a phase change, thermal energy is transferred to or from a substance This energy transfer does not change the temperatur...
Specific Latent Heat During a phase change (i.e. a change of state) thermal energy is transferred to a substance or removed from it, while the temperature of the substance does not change In this c...
Internal Energy When a substance gains or loses thermal energy, its internal energy increases or decreases The internal energy of a substance is defined as: The sum of the total kinetic energy and ...
Temperature Temperature is a measure of how hot or cold objects are Temperature also determines the direction in which thermal energy will flow between two objects (or between an object and its sur...
Solids, Liquids & Gases The three states of matter are solid, liquid and gas The kinetic theory of matter is a model that attempts to explain the properties of the three states of matter In thi...
