Today we did two different labs to learn about thermometers and how they work. Thermometers are generally made with alcohol or mercury; as the gases expand in the thermometer the levels increase and when the gas condences the temperature decreases. We learned that a melting point is the temperature where a substance melts or freezes, it can be either a solid or a liquid here. A boiling point is the temperature where a substance boils, it can be a liquid or a gas here. There are 3 temperature scales: Farenheit, celcius and kelvin. Below is a picture of the equation to covert celcius and farenheit.
Practice Problems
2. To construct a temperature scale you must first find the melting point and boiling point. After these are set it is easy to convert the other temperatures.
3. The celcius scale is based on 10 like the metric system, making it much easier to work with then farenheit. Boiling is 100 and melting is 0.
