A. color, texture
B. boiling point, flammability
C. odor, reactivity
D. solubility, acidity
2. Which of the examples below are chemical properties?
A. density, flammability, and acidity
B. shape, density and melting
C. acidity, flammability and reactivity
D. acidity, reactivity and melting
3. In an old shed you find a rusty, bent anil. What kind of change does the nail
exhibit?
A. physical change
B. chemical change
C. physical and chemical change
D. neither chemical nor physical
All statements are false. Find the mistake and make the statement correct.
1. Physical properties of matter cannot be observed without changing the
identity of the matter
2. Examples of chemical properties are thermal conductivity, state, malleability,
ductility, electrical conductivity, solubility, density and specific heat.
3. Density is the weight of the matter in a given space.
4. The density of a substance is always different at a given pressure,
temperature or by the amount of the substance you currently have..
5. Properties including density, melting point, boiling point, solubility and
specific heat cannot be used to identify substances
6. When a substance undergoes a physical change, its identity changes.
7. Examples of chemical changes are freezing, cutting, bending, dissolving and
melting.
8. Chemical properties describe a substance based on its ability to change into a
new substance that has the same properties.
9. Chemical properties can be observed only when a physical change might
happen.
10. Examples of chemical properties are malleability and reactivity.
11. New substances form as a result of physical change
13. Unlike a chemical change, a physical change does alter the identity of a
substance.
Using the chart of densities on page 161 of science book complete the
following questions.
1. A sample of metal has a mass of 3,623g and a volume of 508 cm. What metal
is it?
2. Suppose that you had a lead ball whose mass is 454g. What is the balls
volume?
3. What is the mass of 15mL sample of mercury
4. A metal object has a mass 25g and a volume of 2.38 cm3. Identify the metal
as silver or lead based on its density.
Identify using properties ( boiling point, melting point, solubility, specific
heat). Check the definition of each of these if you don’t know what they mean.
If you have equal masses of the following pairs of substances which will become
hotter faster, why?
Copper coins or water
Water or ice
Cars aluminum door handle or windshield of a car
Metal buckle of a seatbelt or the cloth strap of the seat belt
