Kinetic Molecular Theory

Question 1

In Boyle’s Law, what’s inversely proportional to volume?

Answer 1

Pressure

Boyle’s Law states that at constant temperature, pressure and volume are inversely proportional (P1V1 = P2V2). This relationship explains why compressing a gas increases its pressure, and why gas expands when pressure is reduced.

Question 2

What is the ideal gas law equation?

Answer 2

PV = nRT

Question 3

As temperature increases, particle speed does what?

Answer 3

Increases

This explains how odors spread through a room.

Question 4

What law states total pressure equals sum of partial pressures?

Answer 4

Dalton’s Law

Dalton’s Law of Partial Pressures states that the total pressure of a gas mixture equals the sum of the partial pressures of each gas (Ptotal = P1 + P2 + P3 + …). This law is crucial in understanding gas mixtures, vapor pressure, and many atmospheric and physiological processes.

Question 5

What type of collision is assumed in ideal gas behavior?

Answer 5

Elastic

Ideal gas behavior assumes perfectly elastic collisions, where kinetic energy is conserved. While real gases deviate from this, especially at high pressures or low temperatures, it’s a useful approximation for many calculations. Understanding deviations from ideal behavior is important in advanced thermodynamics.
