  Physical and Chemicalchanges Physical changes do not cause a substance to become a fundamentally different substance. Chemical changes, on the other hand, cause a substance to change into something entirely new. Chemical changes are typically irreversible, but that is not always the case.
• 6.
  EXAMPLES: • State changesare physical. • Cutting, tearing, shattering, and grinding are physical. • Mixing together substances is physical. • Gas bubbles forming is chemical. • Precipitates forming is chemical. • Rotting, burning, cooking, and rusting (for example) are chemical. • Changes of color or release of odors (i.e. release of a gas) might be chemical.

  • CLASS ACTIVITY •Romans 12:1-2 I appeal to you therefore, brothers, by the mercies of God, to present your bodies as a living sacrifice, holy and acceptable to God, which is your spiritual worship. Do not be conformed to this world, but be transformed by the renewal of your mind, that by testing you may discern what is the will of God, what is good and acceptable and perfect. • After reading the passage, What kind of change would you like to experience? Like a physical change, in which just a superficial part of you is modified? Or like a chemical change, in which you will be totally renewed by a substance? Explain.

  VOLUME, MASS, AND DENSITY A physicalproperty is something that describes a substance by itself and can be observed or measured without changing the identity of the substance. Read the following examples:
• 13.
  “Water can beclear, cool, and wet.” Are those physical properties? Yes, all three of them are. • “Air is invisible, and you breathe it.” Being invisible is a physical property of air. But “you breathe it” doesn’t describe air by itself. It describes what you do to air, so it’s not a physical property of air. • “A car is big and heavy.” Those are two physical properties of a car. • “A book has pages with words and pictures, and a cover.” These are physical properties of a book. • “You read books because you enjoy them or need to know the information in them.” This fact helps describe how you feel about books, but it’s not a physical property of books.

  Mass, Volume, andDensity: Any given substance will have a number of physical properties, but three physical properties apply to all substances. Mass is the amount of matter something has. It can be measured in grams or in kilograms. Because mass is the amount of matter something has, it does not depend on where the thing is found. It could be on Earth’s surface, on top of a mountain, or on planet Mars—its mass measurement would not change.
• 15.
  Density is theamount of mass something has in relation to its volume. Density is equal to mass divided by volume and might be measured in grams per liter, grams per cubic centimeter, or similar units. Any substance will float on a liquid that has a higher density than the liquid does. For example, vinegar has a higher density than olive oil, so when salad dressing separates, the oil floats on top of the vinegar.

   Volume is the amount of space something  takes up. It can be measured in liters or  milliliters, or in cups, gallons, or cubic  centimeters.

  You can usethe triangle to calculate measurements of mass, density and volume. Mass = Density x Volume Density = Mass ÷ Volume Volume = Mass ÷ Density Question Work out the density of a 4 kg lump of metal with a volume of 1.25 m3. Solution: Density = Mass ÷ Volume, so: 4 ÷ 1.25 = 3.2 kg per m3
