CHEM 111 Chapter Notes - Chapter 11: Gas Laws, Jmol, Stoichiometry
Document Summary
Pressure is the force exerted on an object divided by the area over which the force is exerted. An apparatus used to measure atmospheric pressure. A common unit of pressure, defined as the pressure that can support a. A unit of pressure equivalent to 1 mm of mercury. 1 pa = 1 n / m 2. Boyle"s law states that the pressure and volume of a gas sample are inversely related when the amount of gas and temperature are held constant. Charles"s law states that the temperature and volume of a gas sample are directly related when the pressure and the amount of gas are held constant. V 1 / t 1 = v 2 / t 2. Avogadro"s hypothesis states that equal volumes of gases have the same number of particles when they are at the same temperature and pressure.
