Ideal Gas Law Problems Worksheet – Hard Difficulty
Ideal Gas Law Problems Worksheet
Instructions: Solve the following exercises related to the Ideal Gas Law. Be sure to show all your work and justify your answers using appropriate scientific reasoning.
1. **Calculation of Gas Volume**
A sample of gas occupies a volume of 25.0 liters at a pressure of 1.5 atm and a temperature of 300 K. Using the Ideal Gas Law (PV = nRT), calculate the number of moles of the gas.
2. **Analysis of Changing Conditions**
Consider a gas initially at a pressure of 2.0 atm, a volume of 5.0 liters, and a temperature of 250 K. If the pressure is changed to 1.0 atm while the temperature remains constant, what will the new volume of the gas be? Show your calculations using Boyle’s Law.
3. **Multi-step Problem Solving**
A 2.0 mol sample of an ideal gas is in a rigid container at a temperature of 350 K. Calculate the pressure of the gas. Use R = 0.0821 L·atm/(mol·K) for your calculations. Then, if the gas is heated to 400 K while keeping the volume constant, what will be the new pressure?
4. **Real-life Application**
You are ballooning at a high altitude where the temperature is 220 K, and the pressure is 0.5 atm. With a balloon volume of 15.0 liters, compute the number of moles of the gas in the balloon using the Ideal Gas Law. Discuss the implications of altitude on gas behavior.
5. **Conceptual Questions**
Explain how each of the following properties of a gas (temperature, pressure, and volume) affects the state of gas according to the Ideal Gas Law. Provide an example scenario illustrating your points.
6. **Reaction Completion Assessment**
In a closed container, 1.5 moles of an ideal gas exert a pressure of 3.0 atm at a temperature of 350 K. What is the volume of the container? If the gas is then allowed to expand to a volume of 10.0 liters at the same temperature, what will be the new pressure in the container?
7. **Advanced Problem**
Consider a gas confined in a cylindrical tank with a piston. If the piston moves to increase the volume of the gas from 10.0 liters to 40.0 liters while allowing the pressure to drop from 4.0 atm to 1.0 atm, calculate the change in temperature of the gas if the initial temperature was 300 K. Use the Ideal Gas Law to find the final temperature after the expansion.
8. **Data Analysis Question**
You performed an experiment where you measured the volume of a gas at different pressures while keeping the amount of gas and temperature constant. The initial pressure was 1.0 atm, resulting in a volume of 20 L. The pressure was increased to 4.0 atm. Calculate the expected volume using Boyle’s Law and contrast it with the experimental data.
9. **Comparison and Contrast**
Discuss the differences and similarities between real gas behaviors and the Ideal Gas Law predictions. Provide specific examples of gases that deviate from the Ideal Gas Law under certain conditions.
10. **Critical Thinking Problem**
During a day at the beach, a sealed plastic container of gas is left outside. If the temperature rises from 298 K to 340 K due to sun exposure, how does this temperature change affect the pressure inside the container given that the volume remains constant? Utilize the Ideal Gas Law for calculations.
