What is going to happen to the volume of a gas that is put under MORE pressure while keeping the temperature constant?
Responses
A The volume will increase.The volume will increase.
B The volume will decrease.The volume will decrease.
C The volume will fluctuate.The volume will fluctuate.
D The volume will remain constant.
B The volume will decrease.
The correct answer is B: The volume will decrease.
To understand why the volume of a gas decreases when it is put under more pressure while keeping the temperature constant, we can apply the relationship known as Boyle's Law. Boyle's Law states that the pressure and volume of a gas are inversely proportional, meaning that as pressure increases, volume decreases, and vice versa.
To experimentally confirm this relationship, we can perform a simple thought experiment. Let's consider a fixed amount of gas in a container. If we increase the pressure on that gas by, for example, pushing a piston into the container, the gas particles will experience more collisions with each other and the container walls, resulting in an overall decrease in volume. This is because when the gas particles collide more frequently, they exert a greater force on the container walls, leading to a decrease in volume.
Therefore, when a gas is put under more pressure while keeping the temperature constant (assuming it behaves ideally), the volume of the gas will decrease (option B).
