Why are HFCs inappropriate for long-term replacement of CFCs?
HFCs are inappropriate long-term replacements for CFCs due to their high global warming potential, which contributes to climate change. HFCs may be less harmful to the ozone layer than CFCs, but they still have a significant impact on the environment. Thus, other alternatives like natural refrigerants are being explored.
Are all CFCs greenhouse gasses?
No, not all chlorofluorocarbons (CFCs) are greenhouse gases. While CFCs do contribute to ozone layer depletion and are potent greenhouse gases, some CFCs like CFC-12 primarily affect the ozone layer and have a negligible impact on global warming.
How much co2 does a tree absorb per year?
Almost half the mass of a tree is carbon, taken from the atmosphere in the form of carbon dioxide. A tree only takes in carbon when it is growing, and the amount that a tree grows in a year varies from tree to tree. Old trees are bigger and grow more than young trees in a year, usually.
When and where were CFCs banned?
In Montreal in Canada in 1987 nations around the world agreed to stop producing CFCs. This agreement, probably the most successful international agreement ever, is called the Montreal Protocol. Because of this the ozone layer is not longer being damaged, and scientists hope that it will have repaired itself by 2060.
How can chlorofluorocarbons be reduced?
The manufacture of chlorofluorocarbons (CFCs) for industrial use has been banned. When old refrigerators and airconditioning units are scrapped, the CFCs they contain should be trapped for reuse or destruction.
How much CO2 does an oak tree absorb in a year?
An oak tree can absorb about 48 pounds of CO2 in a year.
How do you know if an tree is an organism?
a tree has cells inside it that absorb nutrients, which only living organisms have.

Why chloro fluro carbon is not able to absorb uv radiation?
Chlorofluorocarbons (CFCs) do not absorb UV radiation because their molecular structure does not allow them to interact with UV photons effectively. CFC molecules are not capable of absorbing the high-energy UV radiation due to their specific bond strengths and electronic configuration. This lack of interaction with UV radiation is one reason why CFCs were once widely used in refrigerants and aerosols, contributing to ozone depletion in the upper atmosphere.
What type of tree is Douglas fir?
The roots of a Douglas fir tree absorb water and nutrients
Does bark absorb a lot of water?
Yes, tree bark can absorb water to some extent to help transport nutrients and water throughout the tree. However, bark is not as efficient in water absorption as other parts of the tree such as the roots or inner xylem tissue.
What are the adaptations of the banana tree?
One of the adaptations of the banana tree is it's big leaves which help it absorb sunlight.
Are apples from a tree Heathy?
yes, Because it absorb the nutrients on its soil,
Are CFCs highly toxic?
Chlorofluorocarbons (CFCs) are non-toxic.
How are cfcs released?
CFCs or chlorofluorocarbons are released when a device that holds it is leaking. Also some aerosols release CFCs into the atmosphere.
Can you successfully replant a tree without roots?
No, it is not possible to successfully replant a tree without roots as roots are essential for the tree to absorb water and nutrients from the soil.
Why does a tree need roots?
How are they supposed to absorb water without any roots?
