- 1. 1 Unit 2. PROPERTIES OF MATTER Francesco Scudellari – Comenius Assistant 2010/2011 Francisco Rodriguez Marín Institute – Osuna (Spain)
- 2. 2 What is matter? - Matter is anything that occupies space and can be measured Can you give me some examples of matter?
- 3. 3 Examples of matter Everything around us is made of matter rocks water animals plants planets
- 4. 4 Properties of matter Two pieces of matter cannot occupy the same space – Example: the sun cannot occupy the same place in space as the moon!!
- 5. 5 Bodies of matter, systems of matter Bodies of matter (BODY = CUERPO): Objects having definite limits. Systems of matter: Things with limits that are not precise
- 6. 6 a stone a tree the sea a forest a house a seashell Yourself! (=tú mismo/a) a mountain range Which is a body of matter and which a system of matter? BODY (has got definite Ilimits) BODY SYSTEM (doesn’t have precise limits) BODY BODY BODYSYSTEM SYSTEM
- 7. 7 Extensive properties of matter • Extensive properties depend on the amount (=cantitad) of matter present – Examples: mass, weight, length, volume This cube of stone has mass of 4 kg, a length of 3 cm, and a volume of 27 cm3 Mass, length, volume depend on the amount of matter present! This cube of stone has mass of 120 kg, a length of 20 cm, and a volume of 4000 cm3 !!!!!
- 8. 8 Intensive properties of matter • Intensive properties of matter do not depend on the amount (=cantitad) of matter present Examples of intensive properties: density, color, boiling point (to boil = hervir)
- 9. 9 Example They have different volume, length, mass, etc. But they have the same boiling point (100ºC): BOILING POINT IS AN INTENSIVE PROPERTY! A pan full of water A thermal pool At which temperature does the water in the pan boil? At which temperature does the water in the pool boil? 100ºC 100ºC
- 10. 10 Matter can be measured • Some extensive and intensive properties can be measured For example, we can measure properties such as: LENGTH (=longitud) (extensive) VOLUME (extensive) DENSITY (intensive) MASS….. (extensive) Do you understand the verb to measure? Can you translate it in Spanish? TO MEASURE = MEDIR
- 11. 11 MEASURING LENGTH • Length: the distance between two points We use rulers and measuring tape to determine length RULER MEASURING TAPE In Europe, what are the most common units of measurement for length?
- 12. 12 Units of Length:the Ladder Method Km Hm Dam m dm cm mm ×10 for each step ÷10 for each step For example: 15 m = …… cm1500
- 13. 13 25 Hm = …… m 1 Km = …..…… mm Km Hm Dam m dm cm mm ×10 for each step ÷10 for each step 725 dm = …….. Dam 1,000,000 2,500 7.25
- 14. 14 MEASURING AREA • Area: the space occupied by two dimensions, length × width The area of this rectangle is: 4 × 2 = 8 4 2 What is the unit of measurement for area? Square metres (m )2
- 15. 15 Units of AreaKm2 Hm2 Dam2 m2 dm2 cm2 mm2 ×100 for each step ÷100 for each step 15 cm = …… mm 250 mm = …..cm 13 Km = ……… Dam 2.5 1,500 130,000 2 2 2 2 2 2
- 16. 16 MEASURING VOLUME • Volume: the total space occupied by a body, length × width × height Example: the volume of a fish tank Volume is measured in …………. Cubic metres
- 17. 17 Units of Volume Km3 Hm3 Dam3 m3 dm3 cm3 mm3 ×1000 for each step ÷1000 for each step For example: 12 m = …………. cm 3 3 12,000,000 And 1600 cm = ……… dm 3 3 1.6
- 18. 18 MEASURING CAPACITY • Capacity: the total space occupied by a fluid (another way of measuring volume) Example: the capacity of a bottle of Coke or of a fuel tank I am sure you know at least one unit of measurement of capacity. Can you speak its name aloud?
- 19. 19 One of the most commonly used units of capacity is…. LITRE
- 20. 20 Units of Capacity KL HL DaL L dL cL mL ×10 for each step ÷10 for each step
- 21. 21 MEASURING MASS • Mass: the amount of matter in a body – Measured in grams (g) or kilograms (kg) using a scale A scale is not this: A scale is this:
- 22. 22 Units of Mass Kg Hg Dag g dg cg mg ×10 for each step ÷10 for each step
- 23. 23 MEASURING DENSITY • Density: how concentrated the mass is, mass ∕ volume Example: which object has the higher density, an anvil ( ) or a sponge( ) ? ANSWER: the anvil, because its mass is more concentrated! The unit of measurement for density is…. g/cm (grams over cubic centimetres) 3
- 24. 24 TEMPERATURE • Temperature: the degree of hotness or coldness of a body or system; the thermal energy of a body – Measured in degrees Celsius (°C), Fahrenheit (°F), and Kelvin (K) • How do we measure temperature here in Europe?
- 25. 25 To measure temperature, in Europe we use………. Celsius degrees! (ºC)
- 26. 26 THE END!
