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 9
A 2 mol sample of an ideal gas is at 300 K and 1 atm. Calculate its volume using the ideal gas equation (R = 0.0821 L atm mol⁻¹ K⁻¹).
A gas at 1 atm and 273 K occupies 22.4 L. How many moles of gas are present? (R = 0.0821 L atm mol⁻¹ K⁻¹)
A gas at 2 atm and 300 K has a volume of 10 L. If the pressure is reduced to 1 atm and the temperature is increased to 600 K, what is the new volume?
A gas at 27°C is heated to 127°C at constant pressure. If its initial volume is 5 L, what is its final volume?
A gas cylinder contains 5 moles of oxygen at 2 atm and 300 K. Calculate the volume of the gas. (R = 0.0821 L atm mol⁻¹ K⁻¹)
A gas has a pressure of 100 kPa and a volume of 3 L. If the pressure increases to 150 kPa at constant temperature, what is the new volume?
A gas is compressed from 10 L to 5 L at constant temperature. If its initial pressure was 1 atm, what is its final pressure?
A gas occupies 4 L at 2 atm pressure. What will be its volume at 1 atm pressure, temperature constant?

Describe what happens to the volume of a gas if its temperature is decreased while pressure is kept constant.
Explain why gases are easily compressible.
Explain why the Kelvin scale is used in gas law calculations instead of Celsius.
If the temperature of a gas is increased at constant volume, what happens to its pressure?
If the volume of a gas is doubled at constant temperature, what happens to its pressure?
State Boyle's Law.
What does the 'R' stand for in the ideal gas equation PV = nRT?

What is the value of the universal gas constant R in SI units?
Which law explains why a balloon expands when heated?
Which law is demonstrated when a sealed syringe is pushed in, reducing the volume and increasing the pressure of the gas inside?
