1. Metrics and Measurements
AIM: To be able to accurately measure and record data

2. Volume
Volume is defined by the amount of space an object takes up
Volume can be measured by a ruler or a graduated cylinder
Volume is measured by the units mL or cm3
Volume is measured three different ways
V=LxWxH

3. Three Ways to Measure Volume
Liquids - measure the meniscus using a graduated cylinder
Regular solids - measure length, width, and height with a ruler
Irregular solids - measure water displacement with a graduated cylinder

4. The Metric System
Measure the volume of the liquid in the graduated cylinder.
What is the most volume that could be measured by this graduated cylinder?
16.0 mL
25.0 mL

5. Water Displacement V = Volume final - Volume original
50.0 mL = 150.0mL mL

6. -273 C is known as Absolute Zero
Temperature
Temperature measures how hot or cold an object is
It is the average kinetic energy of an object
Temperature is measured by a thermometer
Temperature is measured by the units Celsius , Kelvin, or Fahrenheit °C °F K
-273 C is known as Absolute Zero

7. Can you read the temperatures?
212 oF
100 oC
98.6 oF
68 oF
32 oF
37 oC
20 oC
0 oC
Boiling Point
Body Temp
Room Temp
Freezing
Point
Fahrenheit oF
Celsius oC

8. Water Boils 100°C or 212°F
Body Temperature  37°C or 98.6°F
Room temperature 20°C or 68 – 70 °F
Water Freezes 0°C or 32°F

9. Absolute zero -273°C or 0 Kelvin
Convert Celsius to Kelvin  C° = K
What would 0°C be in the Kelvin scale?  
What would 100°C be in the Kelvin scale?  
0 °C = 273 K
100°C = 373 K

10. The Metric System
What is the most amount of volume that could be measured by this beaker.
What is the temperature of the water?
