Question

What happens to pressure if volume decreases in a gas?

O Pressure decreases.
O Pressure stays the same.
O Pressure increases and then decreases.
O Pressure increases.

Answer 1

Answer: Pressure increases.

Step-by-step explanation:

If the volume of a gas decreases while the temperature remains constant, the pressure of the gas increases. This is described by Boyle's Law, which states that the pressure and volume of a gas are inversely proportional when the temperature and the amount of gas are held constant. In other words, as the volume decreases, the pressure increases, and vice versa. So, the correct answer is: Pressure increases.
