Q: The concept of absolute zero refers to: (2020)
Solution: Absolute zero refers to the lowest possible temperature, at which gas molecules theoretically stop moving, making both A and B correct.
Steps: 6
Step 1: Understand what temperature is. Temperature measures how hot or cold something is.
Step 2: Learn about molecules. Molecules are tiny particles that make up everything around us.
Step 3: Know that molecules move. At higher temperatures, molecules move faster, and at lower temperatures, they move slower.
Step 4: Discover what absolute zero is. Absolute zero is the theoretical temperature where molecules stop moving completely.
Step 5: Realize that absolute zero is the lowest possible temperature. It is 0 Kelvin, which is equivalent to -273.15 degrees Celsius or -459.67 degrees Fahrenheit.
Step 6: Conclude that at absolute zero, gas molecules have minimal energy and are at their lowest energy state.
