Question: If the pressure of a gas is increased while keeping the temperature constant, what happens to its volume? (2020)

Options:

Correct Answer: It decreases

Exam Year: 2020

Solution:

According to Boyle\'s Law, P * V = constant at constant temperature, so if P increases, V must decrease.

If the pressure of a gas is increased while keeping the temperature constant, what happens to its volume? (2020)

If the pressure of a gas is increased while keeping the temperature constant, what happens to its volume? (2020)

Step 1: Understand that we are talking about a gas and its properties.
Step 2: Know that pressure (P) is how much force the gas particles are pushing against the walls of their container.
Step 3: Recognize that volume (V) is the amount of space the gas occupies.
Step 4: Remember Boyle's Law, which states that pressure multiplied by volume equals a constant when temperature is constant (P * V = constant).
Step 5: If we increase the pressure (P) while keeping the temperature the same, the product P * V must still equal the same constant.
Step 6: Since P is increasing, to keep the product constant, the volume (V) must decrease.
Step 7: Therefore, when pressure increases, the volume of the gas decreases.

Boyle's Law – Boyle's Law states that the pressure of a gas is inversely proportional to its volume when the temperature is held constant.
