Kinetic Theory of Gases

Physics ⇒ Heat and Thermodynamics

Kinetic Theory of Gases starts at 10 and continues till grade 12. QuestionsToday has an evolving set of questions to continuously challenge students so that their knowledge grows in Kinetic Theory of Gases. 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 gas at 27°C is heated to 327°C at constant pressure. If its initial volume is 2 L, what is its final volume?
A gas is kept in a sealed container. If the number of molecules is doubled while keeping temperature and volume constant, what happens to the pressure?
A gas occupies 5 L at 1 atm pressure. What will be its volume at 2 atm pressure at constant temperature?
A gas sample contains 0.5 moles at 300 K and 1 atm pressure. Calculate its volume using the ideal gas equation (R = 0.0821 L atm mol-1 K-1).
A sample of gas at 300 K has a pressure of 2 atm. If the temperature is increased to 600 K at constant volume, what is the new pressure?
According to the kinetic theory, what happens to the pressure of a fixed amount of gas if its temperature is increased at constant volume?
Describe the difference between real gases and ideal gases.
Explain why gases are easily compressible compared to solids and liquids.
Explain why the pressure of a gas decreases when its volume increases at constant temperature.
Explain why the pressure of a gas increases with an increase in temperature at constant volume.
Explain why the temperature of a gas increases when it is compressed rapidly.
If the mass of a gas molecule is m and its root mean square speed is vrms, write the expression for its average kinetic energy.
If the temperature of a gas is doubled (in Kelvin), what happens to the average kinetic energy of its molecules?
State Graham's law of diffusion.
State one limitation of the kinetic theory of gases.
State the ideal gas equation.
The pressure of a gas is 100 kPa at 27°C. What will be its pressure at 127°C, keeping the volume constant?
The root mean square speed (vrms) of gas molecules is given by the formula vrms = sqrt(3kT/m). What does 'k' represent in this equation?
What is the effect on the root mean square speed of gas molecules if the temperature is quadrupled?
What is the value of the universal gas constant R in SI units?
