KMT Postulates
What is the statement that gas particles are in constant, random motion?
What is Postulate B?
What is the force exerted per unit area?
What is pressure?
What is the space occupied by a substance?
What is volume?
What is temperature a measure of?
What is the average kinetic energy of particles?
What is the statement that the volume of gas particles themselves is negligible compared to the volume of the container?
What is part of Postulate A?
What KMT postulate directly explains the cause of gas pressure?
What is Postulate B?
What KMT postulate is most relevant to understanding the compressibility of gases?
What is Postulate A?
What is the relationship between temperature and the speed of gas particles according to the KMT?
What is that higher temperature means faster-moving particles?
What is the statement that describes the type of collisions between gas particles? (Answer: What are perfectly elastic collisions
Postulate C?
If you increase the number of gas particles in a container at a constant temperature and volume, what happens to the pressure?
What does it increase?
If you decrease the temperature of a gas at constant pressure, what will happen to its volume?
What will it decrease?
What temperature scale is directly proportional to the average kinetic energy of gas particles?
What is the Kelvin scale?
What postulate states that the average kinetic energy of gas particles is directly proportional to absolute temperature?
What is Postulate E?
Name three units used to measure gas pressure.
What are Pascals (Pa), atmospheres (atm), millimeters of mercury (mmHg), and pounds per square inch (psi)?
Name three units used to measure gas volume.
What are liters (L), milliliters (mL), cubic meters (m³), and cubic centimeters (cm³)?
How does increasing the temperature of a gas at constant volume affect the pressure and why?
What is that it increases the pressure because the particles collide more frequently and forcefully with the container walls?
What postulate describes the forces of attraction or repulsion between gas particles?
What is Postulate D?
Explain how reducing the volume of a gas container affects the pressure, relating it to the KMT.
What is that reducing the volume increases the frequency of collisions between gas particles and the container walls, thus increasing the pressure?
Explain how the large empty spaces between gas particles (as described by KMT) allow gases to be highly compressible.
What is that the empty space allows the particles to be pushed closer together when pressure is applied, reducing the overall volume?
Explain the relationship between temperature and the frequency and force of collisions between gas particles and the container walls, using the KMT.
What is that higher temperatures lead to faster particles, resulting in more frequent and forceful collisions?
