CHEM1001 Lecture Notes - Lecture 18: Daniel Gabriel Fahrenheit, Fahrenheit, Anders Celsius
Document Summary
Whether we"re talking about the weather, cooking food, or conducting a scientific experiment, we need to know how hot or how cold something is. Although there is an entire field of study devoted to measuring temperature, the focus of this section is on the fundamental measurements of temperature. Temperature enables us to accurately measure and compare climates in different parts of the world. To people in the 21st century, measuring temperature is a quick and easy thing to do. Snow fell and collected in cold weather, and melted into liquid water when the air warmed in spring. Ice melted when placed near a source of heat, and water completely boiled out of a pot on a hot stove. They do not generate a number: they do not tell us that water freezes at 0 c, or that it boils at.
