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 12
A 1.0 mol sample of an ideal gas occupies 22.4 L at standard temperature and pressure (STP). What is the value of STP in terms of temperature and pressure?
A 2.0 L container holds a gas at 300 K and 1.0 atm. If the temperature is increased to 600 K and the volume is doubled, what is the new pressure?
A 5.0 L container holds 0.2 mol of nitrogen gas at 350 K. Calculate the pressure inside the container. (R = 0.0821 L·atm·mol⁻¹·K⁻¹)
A gas at 300 K has a volume of 2.0 L. If the temperature is increased to 600 K at constant pressure, what is the new volume?
A gas cylinder contains 0.5 mol of oxygen at 300 K and 2 atm. Calculate the volume occupied by the gas. (R = 0.0821 L·atm·mol⁻¹·K⁻¹)
A gas is compressed from 8.0 L to 2.0 L at constant temperature. If the initial pressure was 1.0 atm, what is the final pressure?
A gas occupies 10.0 L at 1.0 atm. If the number of moles is doubled at constant temperature and pressure, what will be the new volume?
A gas sample has a pressure of 1.5 atm, a volume of 3.0 L, and a temperature of 400 K. How many moles of gas are present? (R = 0.0821 L·atm·mol⁻¹·K⁻¹)
A sample of gas occupies 4.0 L at a pressure of 2.0 atm. If the pressure is increased to 4.0 atm at constant temperature, what will be the new volume?
Describe the effect of increasing temperature on the kinetic energy of gas molecules.
Explain the difference between an ideal gas and a real gas.
Explain why the ideal gas law fails at very high pressures and very low temperatures.
If the pressure of a fixed amount of gas is doubled at constant temperature, what happens to its volume?
State the ideal gas law and define each variable in the equation.
Which gas law is used to calculate the final pressure when both temperature and volume change?
Which law explains why a balloon expands when heated at constant pressure?
