Study Notes
What is a Thermometer?
- A device used to measure temperature, which is how hot or cold something is.
- Can measure the temperature of different things, such as the air outdoors or something being cooked in the kitchen.
Scales of Temperature
- Temperature is measured in degrees.
- There are two different scales for measuring temperature: Celsius and Fahrenheit.
- It's important to check which scale is being used when reading a thermometer because there are big differences between the scales.
Reading a Thermometer
- Most thermometers use marks and an arrow, or a liquid that rises up to a line, to show the temperature.
- Increments on a thermometer refer to the numbered marks, such as fives or tens, which make the thermometer smaller.
- To read a thermometer, determine the increment, then count the little lines between the increments to find the temperature.
Understanding Increments
- Increments can be counted by twos, fives, or tens.
- Typically, thermometers have lines that stand for single digits or twos.
- Count the little lines from one increment to another to determine what they stand for.
Determining the Temperature
- To find the temperature, look at the arrow or liquid line of the thermometer.
- If it points to an increment number, the temperature is easy to read.
- If it points to a little line, go to the lower number increment and count up, being careful to remember what the lines stand for.
