Presentation Transcript

  1. Matter How and why do we study Matter?

  2. Aim: To DESCRIBE and EXPLAIN matter based on its PROPERTIES and INTERACTIONS

  3. Vocabulary Matter, mixture, pure substance,  element, compound,  Homogeneous, heterogeneous chemical reaction Solute, solvent, solution

  4. What is matter?

  5. What is matter? • Matter is anything that has MASS and VOLUME • MASS – amount of matter in a substance • VOLUME – amount of space matter takes up • What isn’t matter? 

  6. What ISN'T matter? • Energy (light, sound, heat)

  7. CHEMISTRY  • CHEMISTRY is the study of matter.

  8. How can we Describe Matter? Matter can be described by its Physical and Chemical Properties

  9. PHYSICAL PROPERTIES OF MATTER • A physical property of matter is on that can be measured or observed without changing matter to a different substance.  • Properties you can see, hear, smell, or feel with your senses.

  10. Types of Physical Properties Qualitative properties – Descriptions: • Eg.Flavor, colour, texture, hardness, sound, phase Quantitative  properties – Can be measured. Eg. mass, volume, melting point, solubility, boiling point,

  11. Remember KMT? Kinetic Molecular Theory states that: 1. All matter is made up of particles. 2. The particles are in constant motion. 3. There are spaces between the particles .

  12. Matter exists in THREE States (or Phases) Solid                Liquid                  Gas

  13. KMT helps explain different states of matter Compare the particles in different states of matter:

  14. Describe some physical properties of a Strawberry Qualitative Quantitative

  15. Physical Properties 

  16. Physical Properties 

  17. Matter can be described by its CHEMCIAL PROPERTIES • A Chemical Property is the ability of matter to react with another substance to form one or more new substanceswith different properties.

  18. Chemical Properties 

  19. What is the main difference between Physical and Chemical Properties?

  20. What is the main difference between Physical and Chemical Properties? • A physical property is an aspect of matter that can be observed or measured without changing its chemical composition. • Eg. color, mass, volume. • A chemical property may only be observed by changing the chemical identity of a substance. • Eg. Testing reactivity involves seeing what chemical reaction occurs when mixing substances together.

  21. Density is a Physical Property of Matter • Density:     Amount of MATTER in a certain volume of a substance.  • is density a qualitative or quantitative property? • Density = Mass / volume • Units:       g/ml    or       g/cm3

  22. Calculating Density

  23. Calculating Density

  24. Density Calculations 1. A substance weighs 0.56 grams. It has a volume of 3cm3. Calculate the density.

  25. Density Calculations 1. A substance weighs 0.56 grams. It has a volume of 3cm3. Calculate the density.

  26. Density Calculation 2. After each class, Ms. Wilson eats a chocolate bar that weights 12.5 grams. She measures its volume to be 6cm3. Calculate the density of the chocolate bar.

  27. Density Calculation 2. After each class, Ms. Wilson eats a chocolate bar that weights 12.5 grams. She measures its volume to be 6cm3. Calculate the density of the chocolate bar.

  28. Density Calculation 3. A crystal is found that has a volume of 1.5 cm3. If the crystal weighs 4 grams, what is its density?

  29. Density Calculation 3. A crystal is found that has a volume of 1.5 cm3. If the crystal weighs 4 grams, what is its density?

  30. Density Calculation 4. You place a piece of wood in a graduated cylinder. The level of the water in the cylinder moves from 98 mL to 125 mL. a) What is the volume of the piece of wood?

  31. Density Calculation 4. You place a piece of wood in a graduated cylinder. The level of the water in the cylinder moves from 98 mL to 125 mL. a) What is the volume of the piece of wood?

  32. Density Calculation b) If the piece of wood weights 72 grams, what is its density?

  33. Density Calculation b) If the piece of wood weights 72 grams, what is its density?

  34. Density Calculation 5. A graduated cylinder is filled with water to the 55 mL mark. The graduated cylinder with water weights 132 grams. A piece of metal is placed in the water. The water rises to the 105 mL mar. When you re-weigh the cylinder, it now weighs 225 grams. Calculate the density of the metal. 

  35. Density Calculation 5. A graduated cylinder is filled with water to the 55 mL mark. The graduated cylinder with water weights 132 grams. A piece of metal is placed in the water. The water rises to the 105 mL mar. When you re-weigh the cylinder, it now weighs 225 grams. Calculate the density of the metal. 

  36. Density Calculation 5. A graduated cylinder is filled with water to the 55 mL mark. The graduated cylinder with water weights 132 grams. A piece of metal is placed in the water. The water rises to the 105 mL mar. When you re-weigh the cylinder, it now weighs 225 grams. Calculate the density of the metal. 

  37. Density Calculation 6. How does the density of a 250ml cup of water compare to the density of a bathtub containing 55 litres of water?
