Lesson 4

Today we learned more about temperature. Something important to know is the volume of matter changes in response to changes in temperature. Many thermometers contain alcohol or mercury. Most of them now are alcohol because if the thermometer breaks, mercury contains elements that are bad for people. Another thing we learned is that gas expands and contracts as the temperature changes. Furthermore, melting point is also the same thing as freezing point, and boiling point is also condensation point. Temperature can be measured in Celsius, Fahrenheit or kelvin. Celsius is in increments of 10, and its much simpler than Fahrenheit. Celsius is after a man named Anders Celsius, and Fahrenheit is after Daniel G. Fahrenheit. My homework will also help cover a bit more and hopefully answer any questions!
