Metrics and Measurements AIM: To be able to accurately measure and record data
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
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
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
Water Displacement V = Volume final - Volume original 50.0 mL = 150.0mL - 100.0 mL
-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
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
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
Absolute zero -273°C or 0 Kelvin Convert Celsius to Kelvin C° + 273 = K What would 0°C be in the Kelvin scale? What would 100°C be in the Kelvin scale? 0 °C + 273 = 273 K 100°C + 273 = 373 K
The Metric System What is the most amount of volume that could be measured by this beaker. What is the temperature of the water?
