Gas Laws
Physics ⇒ Heat and Thermodynamics
Gas Laws starts at 9 and continues till grade 12.
QuestionsToday has an evolving set of questions to continuously challenge students so that their knowledge grows in Gas Laws.
How you perform is determined by your score and the time you take.
When you play a quiz, your answers are evaluated in concept instead of actual words and definitions used.
See sample questions for grade 11
A 1.0 L container holds 0.5 mol of nitrogen gas at 300 K. Calculate the pressure inside the container. (R = 0.0821 L atm mol-1 K-1)
A 2.0 mol sample of an ideal gas occupies 24.6 L at 300 K. What is the pressure of the gas? (R = 0.0821 L atm mol-1 K-1)
A 3.0 L container holds a gas at 2.0 atm and 400 K. If the temperature is decreased to 200 K and the volume is reduced to 1.5 L, what is the new pressure?
A gas at 300 K has a pressure of 1.5 atm. If the temperature increases to 600 K at constant volume, what is the new pressure?
A gas cylinder contains 5.0 mol of oxygen at 2.0 atm and 300 K. If the gas is compressed to 1/2 its original volume at constant temperature, what is the new pressure?
A gas is compressed from 10.0 L to 2.0 L at constant temperature. If the initial pressure was 1.0 atm, what is the final pressure?
A gas sample has a volume of 500 mL at 27°C. What will be its volume at 127°C, assuming pressure and amount of gas remain constant?
A mixture of gases exerts a total pressure of 3 atm. If the partial pressures of nitrogen and oxygen are 1 atm and 1.5 atm respectively, what is the partial pressure of the remaining gas?
A sample of gas occupies 4.0 L at a pressure of 2.0 atm. What will be its volume if the pressure is increased to 4.0 atm at constant temperature?
Explain the difference between an ideal gas and a real gas.
Explain why real gases deviate from ideal behavior at high pressures.
State Boyle's Law in words.
The combined gas law combines which three gas laws?
The pressure of a gas is doubled while its temperature is kept constant. What happens to its volume?
The temperature of a gas is increased at constant volume. Does the pressure increase, decrease, or stay the same?
The van der Waals equation corrects the ideal gas law for which two factors?
What is the value of the universal gas constant R in SI units?
