Calculate the wavelength of electrons that have reached thermal equilibrium by collision with a moderator at 380K.

Describe pressure from a macroscopic and microscopic perspective. Pressure is a measure of the force per area that substance exerts on its surroundings. In a microscopic scale, pressure arises from the force exerted by molecules or atoms impacting on the walls of a container. Relate Boyles, Charles', and Avogadro's gas laws to observations of gas behavior. Boyle showed that the volume of a sample of a gas is inversely proportional to its pressure (Boyle’s law), Charles and Gay-Lussac demonstrated that the volume of a gas is directly proportional to its temperature (in kelvins) at constant pressure (Charles’s law), and Avogadro postulated that the volume of a gas is directly proportional to the number of moles of gas present (Avogadro’s law). Calculate the values for state functions (n, V, T, P) using the ideal gas equation. PV = nRT Deﬁne the conditions of STP and SATP. STP: Standard Temperature, Pressure: 273.15K (0°C), 101.3kPA. SATP: Standard Ambient Temperature, Pressure: 298.15K (25°C), 101.3kPA. Relate the number density and mass density for a given gas, including quantitative calculations such as mass, molecular weight, and density. Number density is the number of particles per volumf. F ET F In p NE in n PEI Relate partial pressures and the total pressure as described by Dalton’s Law of Partial Pressure. The total pressure of an ideal gas mixture is the sum of the partial pressures of the gases in the mixture. Relate kinetic energy to the temperature of a
