Physical Properties

Physical vs Chemical Properties

 Boiling is an example of a physical change. 

 Correct, density can be measured without a change in composition. 

 Dissolving is an example of a physical change. 

 Measurement of flammability involves a change in composition. 

 All of the above are examples of chemical properties. 

 There is one choice, which is a physical property. 

 A physical property is one that a substance displays without changing its composition. 

Which of the following is an example of a physical property?

Physical and Chemical Properties of Matter

(b) Which properties of zinc can you describe from the
photo? Are these physical or chemical properties?

Changes in Matter (Grade 3)

Matter

Zirconia, an oxide of zirconium, is often used as an affordable
diamond substitute. Just like diamond, it is a colorless
crystal which sparkles under sunlight. Which of the following
physical properties do you think would help in differentiating
between diamond and Zirconia—melting point,
density, or physical state?

Physical Properties Concept

The density of iron is 7.87 g/cm3

Which of the following is not a physical property?

PHYSICAL AND CHEMICAL PROPERTIES OF MATTER | Animation

Physical Properties Example

In the process of attempting to characterize a substance, a
chemist makes the following observations: The substance is
a silvery white, lustrous metal. It melts at 649 C and boils at
1105 C. Its density at 20 C is 1.738 g/cm3. The substance
burns in air, producing an intense white light. It reacts with
chlorine to give a brittle white solid. The substance can be
pounded into thin sheets or drawn into wires. It is a good
conductor of electricity. Which of these characteristics are
physical properties, and which are chemical properties?

Properties of Matter

Classify each of the listed properties of isopropyl alcohol (also
known as rubbing alcohol) as physical or chemical.
a. colorless
b. flammable
c. liquid at room temperature
d. density = 0.79 g>mL
e. mixes with water

(a) Read the following description of the element zinc and
indicate which are physical properties and which are chemical
properties.
Zinc melts at 420 C. When zinc granules are added to dilute
sulfuric acid, hydrogen is given off and the metal dissolves.
Zinc has a hardness on the Mohs scale of 2.5 and a density of
7.13 g>cm3 at 25 C. It reacts slowly with oxygen gas at elevated
temperatures to form zinc oxide, ZnO.

SI Units

The International System of Units (SI) is related to the metric system and is based on seven base units.

Physical & Chemical Changes

A physical change involves a change in the phases of matter, whereas a chemical change involves a change in chemical bonds.&nbsp;

Physical Properties are measurable properties that describe the state of chemical compounds.&nbsp;

Significant Figures: In Calculations

Significant Figures are often involved in chemical calculations.&nbsp;

Scientific Notation

Scientific Notation is used to turn small or large inconvenient numbers into manageable ones.&nbsp;

Density of Non-Geometric Objects

The density of non-geometric objects can be determined using water displacement.&nbsp;

Density

Density represents the mass of an object or compound within a given volume.&nbsp;

Significant Figures: Precision in Measurements

Significant Figures are used to discuss the level of precision in any measurement.&nbsp;

Intensive vs. Extensive Properties

Intensive Properties are independent and Extensive Properties are dependent on the size or amount of substance present

Density of Geometric Objects

The density of geometric objects generally includes spheres, cubes and cylinders.&nbsp;

Significant Figures

Significant Figures are used to determine some level of accuracy within our recorded measurements.&nbsp;

Dimensional Analysis

We use dimensional analysis&nbsp;as a fail proof process to convert from one unit to another.

Chemical Properties

Chemical Properties are observed during chemical reactions.&nbsp;

Temperature

Temperature is a measure of the amount of average kinetic energy of the atoms in a compound.

Metric Prefixes

Metric Prefixes are “labels” that can be placed in front of base units.&nbsp;

Conversion Factors

Conversion Factors represent ratios or fractions composed of different units.&nbsp;

Classification of Matter

Chemistry is the study of matter and the changes it undergoes, with the atom being its basic functional unit.&nbsp;
