CHEM discussion question

1. The Kinetic theory leads to the gas law. However, the “gas consist of molecules in constant random motion” (Ebbing & Gammon, 2012, p. 162). There are five postulates in the kinetic theory. Postulate 1 states that gases are composed of molecules whose size is negligible compared with the average distance between them, postulate 2 states that molecules move randomly in straight lines in all directions and at various speeds, postulate 3 states the forces of attraction or repulsion between two molecules in a gas are very weak or negligible, except when they collide, postulate 4 states when molecules collide with one another, the collisions are elastic, and lastly, postulate 5 states that the average kinetic energy of a molecule is proportional to the absolute temperature (Ebbing & Gammon, 2012, p.163). On the other hand, the temperature plays a role in the degree of freedom. However, when the kinetic energy per degree of freedom, the constant proportionality of the temperature is ½ times Boltzmann constant. Another word, the temperature will decrease when the pressure drops to a certain point, then this result will relate to the equipartition theorem. As for what will cause the pressure in this theory is due to the force and frequency of molecular collisions within the container walls. One major problem that was determined with the kinetic theory was the equation of spatial distribution of temperature and heat.

2. According to our text on pgs 162 - 164, the kinetic theory states that a gas consists of molecules in constant random motion. The 5 postulates that relate to this theory are: 1. Gases are composed of molecules whose size is negligible compared with the average distance between them. 2. Molecules move randomly in straight lines in all directions and at various speeds. 3. The forces of attraction or repulsion between two molecules in a gas are very weak or negligible, except when they collide. 4. When molecules collide with one another, the collisions are elastic; and 5. The average kinetic energy of a molecule is proportional to the absolute temperature.Temperature plays a role in that the higher the temperature, the greater the molecular kinetic energy. Pressure is caused due to the force and frequency of molecular collisions with the container wall. If you increase the number of gas molecules within a container; while not increasing the container size, the frequency of collisions of the gas molecules with the walls of the container will increase causing the pressure to increase. Once the container size is adjusted (increased) this will lessen the frequency of collisions with the container walls and lessen the pressure within the container.

3. Kinetic Theory is the body of theory that explains the physical properties of matter in terms of the motions of its constituent particles. Temperature plays a role in Kinetic theory when molecules are rapidly moving causing friction which causesheat. It also states that the gas pressure is due to the impacts of the molecules moving fast
