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 10
A 1.0 mol sample of an ideal gas occupies 22.4 L at STP. What is the pressure in atm?
A 2.0 L container holds a gas at 300 K and 1 atm. If the temperature is increased to 600 K and the pressure is kept constant, what is the new volume?
A gas at 1 atm and 273 K has a volume of 22.4 L. How many moles of gas are present? (R = 0.0821 L·atm/mol·K)
A gas at 2 atm and 300 K occupies 5 L. What will be its pressure if the volume is reduced to 2.5 L at constant temperature?
A gas at 27°C is heated to 127°C at constant pressure. If its initial volume was 5 L, what is its final volume?
A gas cylinder contains 0.5 mol of gas at 300 K and 2 atm. What is the volume of the gas? (R = 0.0821 L·atm/mol·K)
A gas has a pressure of 2 atm and a volume of 3 L. If the pressure is reduced to 1 atm at constant temperature, what is the new volume?
A gas occupies 4.0 L at 1.0 atm. What will be its volume at 2.0 atm, temperature constant?
A gas sample has a volume of 10 L at 1 atm. If the pressure is increased to 5 atm at constant temperature, what is the new volume?
A sample of gas at 300 K has a volume of 2.0 L. If the temperature increases to 600 K at constant pressure, what is the new volume?
Describe the effect of decreasing the temperature of a gas at constant volume.
Describe what happens to the pressure of a fixed amount of gas if its temperature is increased at constant volume.
Explain why gases are easily compressible compared to solids and liquids.
Explain why the Kelvin scale is used in gas law calculations instead of the Celsius scale.
Explain why the volume of a gas increases when the temperature increases at constant pressure.
If the pressure of a gas is doubled at constant temperature, what happens to its volume?
State Charles's Law.
What is the standard temperature and pressure (STP) for gases?
