Faster-moving particles mean higher temperatures, while slower ones mean lower. Scales like Fahrenheit and Celsius give standardized points for freezing, boiling, and body temperature, allowing easy temperature comparison across different systems. 00:00 Intro 00:26 What is temperature? 02:32 How do thermometers work? 05:42 Celsius and Fahrenheit scale 07:00 Summary Khan Academy is a nonprofit organization with the mission of providing a free, world-class education for anyone, anywhere.
