Final Part 1

Front

What is the Kinetic Molecular Theory?

Back

A theory that explains the behavior of gases in terms of particles in constant motion, where the energy of the particles is related to temperature.

Front

What happens to particle motion when temperature increases?

Back

Particle motion increases as temperature increases.

Front

What is the difference between solids, liquids, and gases according to the Kinetic Molecular Theory?

Back

They differ in the freedom of motion and the strength of attractions between particles.

Front

Why do liquids have a constant volume but not a constant shape?

Back

Because of significant attractions between particles and their freedom of motion.

Front

What is the average distance between gas particles compared to their diameter?

Back

The average distance is about 10 times their diameter.

Front

What is the nature of attractions between particles in a liquid?

Back

The attractions are strong but not strong enough to prevent movement.

Front

What is the primary characteristic of particles in a gas?

Back

Particles are in constant motion and have high energy.

Front

How do temperature changes affect the motion of particles in solids?

Back

Increased temperature causes particles to vibrate more, but they remain in fixed positions.

Front

What is the relationship between particle motion and temperature in gases?

Back

As temperature increases, the average kinetic energy of gas particles increases, leading to faster motion.

Front

What defines the shape of a solid?

Back

The fixed positions of particles due to strong attractions between them.
