Metric Length and Temperature: Temperature in the Metric System

The video tutorial explains how thermometers are used to measure temperature, detailing both traditional and digital types. It covers the Fahrenheit scale used in the English system, where water freezes at 32°F and boils at 212°F, and the Celsius scale used in the metric system, where water freezes at 0°C and boils at 100°C. The tutorial also demonstrates how to compare temperatures between the two scales using a common household thermometer.

What is the primary function of a traditional thermometer?

• To measure humidity

• To measure temperature

• To measure wind speed

• To measure air pressure

In the Fahrenheit scale, at what temperature does water freeze?

• 100 degrees

• 0 degrees

• 212 degrees

• 32 degrees

How many degrees are there between the freezing and boiling points of water in the Celsius scale?

• 32 degrees

• 212 degrees

• 100 degrees

• 180 degrees

What is the Celsius equivalent of 81 degrees Fahrenheit?

• 25 degrees

• 28 degrees

• 30 degrees

• 32 degrees

Why do many thermometers have both Fahrenheit and Celsius scales?

• To measure two different temperatures at once

• To allow easy comparison between the two scales

• To provide a backup in case one scale fails

• To measure temperature in two different units simultaneously
