The volume, V, of a gas is usually given in liters. Only four measurable properties are used to describe a gas: The quantity amount of the gas is usually expressed in moles n. Memorize these for the exam so you can convert units where necessary: All collisions between gas particles are perfectly elastic meaning that the kinetic energy of the system is conserved.
Explanation In this example, choice 1 is incorrect. The following is a list of all of the standard pressure in every unit for pressure. Choices 2, 3, 4, and 5 all describe an ideal gas.
The SI unit for pressure is the pascal Pabut other pressure terms include atmospheres atmsmillimeters of mercury mmHgand torr. The volume only becomes significant if gas particles collide often, increasing the chances that intermolecular forces will hold them together.
The temperature, T, of gases must always be converted to the Kelvin temperature scale the absolute temperature scale. Measuring the Pressure of a Gas Gas pressure is a gauge of the number and force of collisions between gas particles and the walls of the container that holds them.
All of the gas laws rely on some basic assumptions that are made about gases, and together they constitute what it means for a gas to be in an ideal state. Gases have no intermolecular attractive or repulsive forces. Choice 1 makes an incorrect assumption: The particles of a gas move in random straight line paths until a collision occurs.
The volume occupied by gas particles is only significant at very low pressures.
In an ideal state All gas particles are in constant, random motion.All of the gas laws rely on some basic assumptions that are made about gases, and together they constitute what it means for a gas to be in an ideal state. In an ideal state In an ideal state All gas particles are in constant, random motion.
