Question

Use kinetic molecular theory to explain the relationship between: 1. Pressure and volume of a confined gas 2. Volume and temperature of a confined gas 3. Pressure and temperature of a confined gas 4. Moles and volume of a gas

I need a written explanation about each relationship.

Answer 1

6 pressure and volume of a confined oras : (pal) Grases can be Compressed because most of the volume of a go is empty spacer 9 we compress agas without changing its temperature, the average Kinetic energy of the gas particles stays the same There is no change in speed with which the particles more, but the container is smaller Thus, the particle travel from one end of the Container to the other in a shooter period of time. Any increase in the frequency of coursions with the ways must lead to an increase in the pressure of gas. Thus, the pressure of agos becomes largen as the volume of the gas becomes Smaller Boyle's Law (pat) (3) volume and Temperature of a confined gas : I (VAT) charles Law The average kinetic energy of the particles in a gas is proportional to the temperature of the gas. Because the mass of these particles is constant, the partides must move faster as the gas becomes Warmer. If they move faster, the particles will exert a greater force on the Container each time they hit the walls, which leads to an increase in the pressure of gas. If the walls of the Container are flexible, it wil expand untill the pressure of the gas once more balances the pressure of the atmosphere. The volume of the gas therefore becomes larger as the temperature of the gas increases.

Udle Pressure and temperature of a Confined gas: (POT) Amontons Law. The last postulate of the kinetic molecular I theory States that the average kinetic energy of agas particles depend only on the temperature of the gees. Thus, the average Kinetic energy of the Igas particles increases as the gas becomes Warmer The faster these particles are moving when they hit the wall, the greater the force they exert on the wall. since, the force per comision becomes larger, as the temperature increases the pressure of the gas must increases as well 1 Moles and volume of a gas Avogadro's Hypothesis (van) As the no. of gas particles increases, the frequency of couisions with the waus of the Container must increase. This in turn, leads to an increase in the pressure of gas. Flexible Containers, such as a balloon, will expand until the pressure of the gas inside the balloon once again balances the pressure of the gas outside. Thus, the volume of the gas is proportional to the no. of gas particles.
