Answers
What ozone layer is earth's protective shield? -
correct answer ✅Stratospheric ozone
What is ODP? -
correct answer ✅Ozone Depletion Potential. Measures the ability
of a substance to destroy ozone in the stratosphere.
How does depleting stratospheric layer affect humans and
environment -
correct answer ✅Global Warming. Skin cancer. Cataracts.
Decreased Crop yield
Damage to Marine organisms
Which chemical containing refrigerants affect the depletion of the
stratospheric layer? -
correct answer ✅Chlorine containing refrigerants.

Answers
____ is the element of a CFC and HCFC molecules that causes ozone
depletion -
correct answer ✅Chlorine
What happens when a chlorine atom encounters an ozone
molecule? -
correct answer ✅It takes one of the ozone 3 oxygen atoms forming
a compound called chlorine monoxide (CIO) leaving an oxygen 02
molecule behind.
How long does a single chlorine atom last in the Stratosphere and
how many molecules does it destroy? -
correct answer ✅It can last in the stratosphere for 120 years and
destroy up to 100,000 ozone molecules
The chlorine in CFCs and HCFCs will neither dissolve in water nor
break down into compounds that dissolve in water. (so they do not
rain out of the atmosphere) T/F -
correct answer ✅True

Answers
What are HFCs? Do they contain Chlorine? High or Low GWP? -
correct answer ✅Hydrofluorocarbons. They do not contain
Chlorine. High GWP.
What is GWP? -
correct answer ✅Global Warming Potential. Was established to
provide comparisons of the global warming impacts of different
gases over a span of time.
Which molecule is used as the baseline measurement for GWP and
has a value of 1 -
correct answer ✅Carbon Dioxide (CO2)
R-410A is not a HFC. T/F -
correct answer ✅False
Does R-410A have a high/low GWP? if so how much? -
correct answer ✅R-410A have GWP thousands of times greater
compared to CO2.
