Gas, pressure and volume Supervisor Reza Fahad Hanon  Gas Gas is a state of matter in which the forces of attraction between its molecules are weak. The gas’s mass and number of molecules remain constant in all of these relations.  Boyle’s Law The pressure of a gas is inversely proportional to its volume. 𝟏 P = 𝑽 The correlation between the pressure and volume of a fixed mass of gas at a constant temperature can also be stated as : P1V1 = P2V2  Charles’s L a w  This relation shows that the volume of a gas is directly proportional to its temperature.  V∝T 𝑉1 𝑉2  Law = 𝑇1 𝑇2  Law of Pressure  P ∝ T : This equation indicates that the pressure of a gas is directly proportional to its temperature. 𝑃1 𝑃2  = 𝑇1 𝑇2  As pressure is the force per unit area: Higher temperature leads to greater pressure. ‫ا‬  Ideal Gas Equation An ideal gas is characterized by the following attributes: Its molecules have an low volume. Collisions among its molecules are elastic. Its molecules have no interactions with each other except during collisions.  Energy is the ability to do work Units of measurement of energy is joule Types of Energy  Kinetic Energy is the energy associated with the object’s motion. 1 2 Law : K.E = m 𝑐 2  Mechanical Energy Potential Energy Mechanical energy is Potential energy is the energy stored in an object or system the energy associated of objects. Potential energy with the mechanical can transform into a more movement. of objects. obvious form of kinetic energy. This type of energy can also be referred to E=m.h.g as motion energy. T h a n k y o u a ll
