Understanding the Combined Gas Law

What is the primary focus of the combined gas law?

• Relating pressure, volume, and temperature of a gas

• Measuring the weight of gases

• Determining the color of gases

• Calculating the speed of gas particles

In the first example, which law is applied when temperature is constant?

• Boyle's Law

• Ideal Gas Law

• Avogadro's Law

• Charles's Law

What is the final volume when the pressure changes from 1.3 ATM to 4.7 ATM, given the initial volume is 2.3 L?

• 2.0 L

• 3.0 L

• 1.5 L

• 0.64 L

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

• Kelvin is used to measure pressure

• Celsius is not a real temperature scale

• Kelvin is the standard unit for temperature in gas laws

• Kelvin is easier to calculate

What is the final volume when the temperature changes, given the initial volume and temperature in Celsius?

• 3.13 L

• 4.0 L

• 1.0 L

• 2.5 L

In the third example, what remains constant?

• Volume

• Pressure

• Moles of gas

• Temperature

How do you convert mmHg to atmospheres?

• Multiply by 760

• Divide by 760

• Add 273

• Subtract 273

What is the final volume when the pressure is converted from mmHg to atmospheres?

• 6.5 L

• 8.6 L

• 7.0 L

• 5.0 L

Why is it important to have the same units on both sides of the gas law equation?

• To make calculations easier

• To simplify the equation

• To ensure accuracy and consistency

• To avoid using a calculator

What is the conversion factor for 1 atmosphere in mmHg?

• 1000 mmHg

• 760 mmHg

• 273 mmHg

• 101.3 mmHg
