The Kelvin Scale and Absolute 0: Understanding Temperature Limits

The video tutorial explores temperature scales, focusing on the Celsius and Kelvin scales. It explains the concept of absolute zero, the lower limit of temperature, and how it is determined by extrapolating gas pressure data. The tutorial also covers the Kelvin scale, which measures temperature relative to absolute zero, and provides a method for converting between Celsius and Kelvin.

What is the lower limit of the Celsius temperature scale?

• 273 degrees Celsius

• 0 degrees Celsius

• -100 degrees Celsius

• -273 degrees Celsius

What happens to the pressure of a gas as it approaches absolute zero?

• It decreases to zero

• It remains constant

• It increases

• It becomes negative

At what temperature do particles in a substance stop moving?

• -273 degrees Celsius

• 0 degrees Celsius

• 100 degrees Celsius

• 273 Kelvin

How is 0 Kelvin related to the Celsius scale?

• 0 Kelvin is equal to 273 degrees Celsius

• 0 Kelvin is equal to -273 degrees Celsius

• 0 Kelvin is equal to 100 degrees Celsius

• 0 Kelvin is equal to 0 degrees Celsius

How do you convert a temperature from Celsius to Kelvin?

• Add 273 to the Celsius temperature

• Subtract 273 from the Celsius temperature

• Multiply the Celsius temperature by 273

• Divide the Celsius temperature by 273
