Absolute zero

The transcript discusses the concept of particles ceasing to vibrate as they approach absolute zero. It highlights that while physicists have managed to get close to absolute zero in laboratory settings, it is considered impossible for any natural system to achieve this state.

What happens to particles at absolute zero?

• They start moving rapidly.

• They stop vibrating.

• They change color.

• They expand.

What have physicists achieved in the laboratory regarding absolute zero?

• They have surpassed absolute zero.

• They have reached absolute zero.

• They have failed to approach absolute zero.

• They have come close to absolute zero.

What is the main focus of physicists in the context of absolute zero?

• To develop new technologies.

• To use it for energy production.

• To understand its effects on particles.

• To create new elements.

Why is it challenging to reach absolute zero in natural systems?

• Because of insufficient energy.

• Due to the laws of thermodynamics.

• Due to environmental factors.

• Because of the lack of technology.

Which of the following is true about absolute zero?

• It is easily achievable in nature.

• It is a theoretical temperature.

• It is the average temperature of space.

• It is the boiling point of water.
