Exploring Boyle's Law and Its Applications

What does Boyle's Law describe?

• The relationship between pressure and temperature of a gas at constant volume

• The direct relationship between pressure and volume of a gas

• The relationship between volume and temperature of a gas at constant pressure

• The relationship between pressure and volume of a gas at constant temperature

What happens to the volume of a gas if the pressure on it is increased, according to Boyle's Law?

• The volume remains unchanged

• The volume increases

• The volume first decreases then increases

• The volume decreases

Why does the graph of Boyle's Law not cross the x-axis?

• Because volume can become negative

• Because pressure can become negative

• Because the graph actually crosses the x-axis

• Because volume cannot become negative

In the first example, what was the original volume of the gas?

• 600 milliliters

• 100 milliliters

• 120 milliliters

• 500 milliliters

What was the new pressure calculated in the first example?

• 120 kilopascals

• 600 kilopascals

• 500 kilopascals

• 6.0 x 10^2 kilopascals

How does the pressure change when the volume of a gas is compressed?

• It decreases

• It remains the same

• It increases

• It first increases then decreases

What is the significance of using significant figures in calculations?

• To make the numbers look nicer

• To simplify the calculation process

• To match the precision of the measurement tools

• To increase calculation speed

Why do we use scientific notation in reporting results?

• To avoid using significant figures

• Because it is easier than using regular numbers

• To accurately represent very large or small numbers

• To comply with Boyle's Law

In the second example, what was the initial pressure of the gas?

• 1 atmosphere

• 1.25 atmospheres

• 32 milliliters

• 40 milliliters

What was the new volume found in the second example?

• 32.0 milliliters

• 40 milliliters

• 100 milliliters

• 1.25 milliliters
