*7.8C Temperature and Kinetic Energy Flashcard

Front

What happens to the state of matter of a substance when its temperature changes?

Back

The state of matter can change because temperature affects the kinetic energy of the particles, leading to changes in their arrangement.

Front

What happens to the average kinetic energy of gas particles when the temperature is increased?

Back

The average kinetic energy of gas particles increases.

Front

Why does a liquid turn into a gas when heated?

Back

Heating the liquid increases the kinetic energy of its particles, allowing them to overcome intermolecular forces and become a gas.

Front

What is the relationship between temperature and kinetic energy of particles?

Back

As temperature increases, kinetic energy increases.

Front

What effect does decreasing temperature have on the particles of a substance?

Back

Particles move slower and come closer together.

Front

Define kinetic energy in the context of particles in a substance.

Back

Kinetic energy is the energy that particles possess due to their motion; it increases with temperature.

Front

What is the effect of temperature on the motion of particles in a solid?

Back

In a solid, as temperature increases, particles vibrate faster.

Front

How does temperature affect the arrangement of particles in a gas?

Back

In a gas, as temperature increases, particles spread apart and move more freely.

Front

What is the process called when a solid turns into a liquid due to temperature increase?

Back

Melting.

Front

What is the process called when a liquid turns into a solid due to temperature decrease?

Back

Freezing.
