The temperature of the air changes from time to time. Body temperature changes also when one has fever. Temperature is measured in degrees, A Celsius thermometer is used to measure temperature Celcius is the temperature scale with 0 degree as the freezing point and 100 degrees as the boiling point of water. The room temperature is 20c. The normal body temperature is 37 .c or 37 degrees Celsius. Celsius Fahrenheit balling- THE THERMOMETER Glass tube Scale - blood Mercury Glass bulb freezing. Temperature rises or falls. If a temperature of 37 .C rises to 40 .C, the temperature change is .C. When you say 10 'C above room temperature, it means 20C+10C=30 C. You add 10C to room temperature which is 20 .C. When you say 20 'C below the boiling point it means 100 .C-20 .C=80 .C. When the temperature drops below zero to -20 C, we say 20 degrees below zero.

It is measured in cubic units, the most common of which are the are cubic centimetres (cm ' ), cubic decimetres (dm'), and cubic metres (m' ) 1 cm=1 000 mm ' 1 dm' = 1 000 cm' 1 m'= 1000 dm' 1m'= 1000 000 cm' Study the following and look for the pattern 2 dm'= 2 000 cm' 2 000 cm ' = 2 dm' 3 dm ' = 3 000 cm' 3 000 cm ' = 3 dm 4.5 dm' = 4 500 cm 4 500 cm= 4.5 dm' To convert from one cubic unit to another, we can use the appropriate conversion factor. Study the following: 1. 2 dm'=_ Since 1 dm '= 1 000 cm then 2 dm'= 2x 1 000 cm' = 2 000 cm 2. 4.5 m'= cm Since 1 m'= 1 000 000 cm ' then 4.5 m '=4.5x 1 000 000 cm' = 4 500 000 cm' 3. 3 500cm = dm Since 1 000 cm ' =1 dm then 3 500 cm'=(3 500+1 000)x 1 dm' = 3.5x 1 dm' =3.5 dm 4. 7 300 000 cm = m 3 Since 1 000 000 cm ' =1 m' then (7 300 000-1 000 000) x 1 m' = 7.3x1 m' =7.3 m' -When converting to a larger to a smaller unit, use multiplication -When converting from a smaller to a larger unit divide.
