Write what each word means, using the article.

Do not copy the article. Write two things you learned, the way you would explain them to a friend.

Answers below are taken from the article’s stored facts, so they match what the student read.

1. What is the third law of thermodynamics?States that absolute zero is unattainable in a finite number of steps
2. Why is absolute zero important?It is a fundamental limit that helps scientists understand how matter behaves when it is almost nothing. It is also used to study special phenomena like superconductivity.
3. How do scientists try to reach temperatures close to absolute zero?They use techniques such as laser cooling, evaporative cooling, and magnetic cooling to slow atoms and remove energy, getting very close to 0 K.

Entropy: A measure of disorder or randomness in a system.
Cryogenics: The study and production of very low temperatures and their effects.
Bose-Einstein Condensate: A state of matter formed by cooling bosons to near absolute zero.
