Understanding Pressure Law

What does the Pressure Law state about the relationship between pressure and temperature?

• Pressure is directly proportional to temperature in Celsius.

• Pressure is unrelated to temperature.

• Pressure is directly proportional to absolute temperature.

• Pressure is inversely proportional to temperature.

What is the formula derived from the Pressure Law?

• P1/T1 = P2/T2

• P1 * T1 = P2 * T2

• P1 + T1 = P2 + T2

• P1 - T1 = P2 - T2

How does an increase in temperature affect the motion of gas particles?

• Gas particles stop moving.

• Gas particles move at a constant speed.

• Gas particles move faster.

• Gas particles move slower.

What happens to the pressure of a gas when its temperature increases in a closed container?

• Pressure remains constant.

• Pressure decreases.

• Pressure fluctuates randomly.

• Pressure increases.

How does the graph of pressure vs. absolute temperature appear?

• A curved line passing through the origin.

• A straight line passing through the origin.

• A straight line not passing through the origin.

• A horizontal line.

At what temperature in Celsius does the pressure vs. temperature graph touch the x-axis?

• 273 degrees Celsius

• 100 degrees Celsius

• -273 degrees Celsius

• 0 degrees Celsius

Why is it important to convert temperature from Celsius to Kelvin in gas law calculations?

• Kelvin is easier to calculate.

• Kelvin is the standard unit for temperature.

• Celsius is not accurate.

• Kelvin is used for all scientific calculations.

In the given example, what is the initial pressure of the gas in the cylinder?

• 300 kPa

• 200 kPa

• 100 kPa

• 400 kPa

What is the final temperature in Kelvin when the cylinder is moved outdoors?

• 300 K

• 308 K

• 273 K

• 315 K

What is the final pressure of the gas after the temperature change in the example?

• 210,000 Pa

• 215,000 Pa

• 205,000 Pa

• 220,000 Pa
