What Is Temperature? (Part 2).

๐ŸŽฏ Your mission

Understand the idea. Then look for it everywhere.

โšก The twist

Mixing two safe things doesn't always make a safe thing.

Temperature measures how fast particles are moving. At absolute zero, particles have the least possible energy. Heating matter increases particle motion and can cause state changes.

Key Words

  • density
  • mass

Steps

Step 1 โ€” Read
