|
the volume of the gas increases

|
|
the volume of the gas decreases
|
|
|
the volume of the gas increases and then decreases
|
Detailed explanation-1: -So, when the gas undergoes compression, there is a decrease in pressure with an increase in volume.
Detailed explanation-2: -The gas volume reduces as pressure rises because gas particles are pushed closer together.
Detailed explanation-3: -As the pressure on a gas increases, the volume of the gas decreases because the gas particles are forced closer together. Conversely, as the pressure on a gas decreases, the gas volume increases because the gas particles can now move farther apart.
Detailed explanation-4: -Decreasing the volume of the container forces the particles to collide more often, so the pressure is increased. A good example of this is when you fill a tire with air. As more air goes in, the gas molecules get packed together, reducing their volume. As long as the temperature stays the same, the pressure increases.
