Molecular Motion LC

Front

What is a gas molecule?

Back

A gas molecule is a particle that is widely spaced and moves freely, representing the gaseous state of matter.

Front

What is heat?

Back

Heat is a form of thermal energy that is associated with the kinetic energy of particles.

Front

Which state of matter has closely packed and organized particles?

Back

Solid.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of motion.

Front

What is a molecule?

Back

A molecule is a particle made of two or more atoms.

Front

What is the difference between solids, liquids, and gases?

Back

Solids have closely packed particles, liquids have loosely packed particles that can flow, and gases have widely spaced particles that move freely.

Front

What happens to the motion of particles when heat is added?

Back

When heat is added, the motion of particles increases, leading to a change in state (e.g., solid to liquid).

Front

What is thermal energy?

Back

Thermal energy is the total energy of all the particles in a substance, related to temperature.

Front

How do gas molecules behave in a container?

Back

Gas molecules move freely and spread out to fill the entire container.

Front

What is the relationship between temperature and molecular motion?

Back

As temperature increases, molecular motion increases.
