  2. Temperature • Temperature is described as the amount of warmness or coldness in an object. The device used to measure temperature is a thermometer.

  3. A typical thermometer is a calibrated, or numbered, glass tube containing mercury. • The silver mercury in the tube rises, or expands, when warmth of an object increases. The mercury falls when the warmth of an object decreases. The calibrated scale on the tube of the thermometer allows us to read the temperature.

  4. Measuring temperature • There are two systems for measuring temperature. Both of these systems measure temperature in degrees. • The first scale is measured in degrees Faharenheit. The range from freezing point to boiling point on this scale is 32 to 212 degrees. • The other scale is measured in degrees Celsius. Sometimes it is also referred to as the Centigrade scale. The range from freezing point to boiling point on this scale is 0 to 100 degrees

  5. How HOT or COLD? • The average human body temperature is 98.6 degrees Fahrenheit, or 37 degrees Celsius. • A hot summer's day in Florida would be close to 100 degrees Fahrenheit, or 38 degrees Celsius. • A comfortable room temperature would be around 70 degrees Fahrenheit, or 21 degrees Celsius. • A pot of boiling water is 212 degrees Fahrenheit, or 100 degrees Celsius. • The temperature of a pitcher of iced tea would be around 57 degrees Fahrenheit, or 14 degrees Celsius. • A cold winter day with a high wind chill factor might be below freezing at 23 degrees Fahrenheit, or -5 degrees Celsius
