CFC's and Ozone: Understanding the Uses and Impact

This lesson provides knowledge about CFC's and their uses, including their role as propellants and coolants. It also explores the impact of ozone depletion and the non-flammable alternatives to CFC's. Students will gain an understanding of the chemical compounds and their effects on the environment.

Learning – Teaching Plan _ CFC’s and Ozone (Enrichment)
Lesson Overview
CFCs is standing for chlorofluorocarbon that contains the fluorine, chlorine, and carbon. CFC is also known as the Freon, and it is
mostly useful as the propellants and coolants. This lesson will plan for students to provide knowledge regarding the CFC and its
uses. CFCs is the family of chemical compounds that contain the non-flammable alternatives, nontoxic.

This lesson will plan for students to provide
knowledge regarding the CFC and its uses.
By this lesson, the student will learn that
CFCs is stands for chlorofluorocarbon that
contains the fluorine, chlorine, and carbon.
By this lesson, the student will understand
that CFC is also known as the Freon and it
is mostly useful as the propellants and
coolants. It is the organic compound that
includes the fluorine, chlorine, carbon and
it is developed as a volatile derivative of
ethane and methane
CFCs is the family of chemical compounds
that contain the non-flammable alternatives,
nontoxic. One of the essential factors that
make up CFC is chlorine. The producer of this
element has been phased out under the
Montreal protocol, and it can be replaced with
another commodity like hydrofluorocarbons.

Explore: CFC is also known as the
Freon, and it is most useful as the
propellants and coolants. It is the
organic compound that includes the
fluorine, chlorine, carbon and it is
developed as a volatile derivative of
ethane and methane.
CFCs is the family of chemical
compounds that contain the non-
flammable alternatives, nontoxic. One
of the essential factors that make up
CFC is chlorine.

phased out under the Montreal
protocol, and it can be replaced with
another commodity like
hydrofluorocarbons. Due to the
reaction with chlorine, hydrogen,
oxygen, bromine, nitrogen, ozone gas
can destroy.
