Question

You have a gas in a containers fitted with a piston and you change one of the conditions of the gas such that a change takes place, as shwon below. state three distinct changes you can make to accomplish this, and explain why each would work

Answer 1

Three ways to change the conditions of a gas under a piston are adjusting the temperature, volume, or number of molecules. These changes correspond to Charles's Law, Boyle's Law, and Avogadro's Law respectively, causing changes in volume, pressure, and number of collisions within the gas.

Step-by-step explanation:

There are three distinct changes you can make to a gas under a piston to make a noticeable change in its conditions: changing the temperature, volume, or the number of molecules of the gas, according to the Gas Laws.

1. Temperature Change: According to Charles's Law, if you increase the temperature, the gas will expand increasing its volume, as long as the pressure remains constant. This is due to the increase in the kinetic energy of the gas particles.
2. Volume Change: According to Boyle's Law, if the volume of the gas is reduced (by pushing the piston in), the pressure of the gas will increase, assuming the temperature remains constant. This is because the particles are confined to a smaller space and collide more often with the container walls.
3. Change in Number of Molecules: By Avogadro's Law, an increase in the number of gas molecules (assuming temperature and pressure remain constant) will result in an increase in volume. More gas molecules mean more collisions and hence increased volume.
