Why is it important to phase out the use of chlorofluorocarbons?
Wiki User
∙ 10y ago
Countries agreed at the Montreal Conference to ban the use of chlorofluorocarbons (CFCs). It was clear to everyone that CFCs were damaging the ozone layer and this could lead to severe damage to humans. This ban has been the most successful international intervention ever. No CFCs are now being released and scientists hope the ozone level will have self-repaired by 2060 (CFCs hang about in the atmosphere for up to 75 years!).

Do they make 3 phase oven for home use?
Three phase ovens are made for home use. It is important however to know if the home is wired for three phase or for single phase.
Why is it important to use the placebo in the phase 3 trial?
so that you can compare the results with the real medicine.
Why is important for three phase supply voltage to be in-phase?
The phase voltages (i.e. line-to-neutral in a 4-wire system, or line-to-line in a 3-wire system) of a three-phase system are displaced from each other by 120 electrical degrees. Each phase voltage, in fact, is rarely in phase with its phase current, as the phase-angle (the angle by which a phase current lags or leads its phase voltage) is determined by the load not by the supply.In general, most loads are resistive-inductive so the phase current usually lags the phase current.So, to answer your question, it's not important that a phase current is in phase with its phase voltage -if that is what you are asking.
Do televisions use single-phase or 3-phase power?
Answer 1: TV's use single-phase power. Answer 2: TV's use single phase power of 220 or 110 volts ac power depending on what part of the world you live in.
An important difference between a universal and a split-phase motor is that the split-phase motor has?
two windings on the stator
How can you use the word chlorofluorocarbons in a sentence?
Chlorofluorocarbons are thought to deteriorate the ozone.
What do scientists predict the banning of the use of chlorofluorocarbons will do?
Banning the use of chlorofluorocarbons has begun to allow the ozone layer to recover. this improvement is predicted to continue.
Do they make 3 phase oven for home use?
Three phase ovens are made for home use. It is important however to know if the home is wired for three phase or for single phase.
What was the ingredient in aerosol cans that banned them from use?
chlorofluorocarbons (CFCs)
Albuterol contains cfc what does this mean?
Albuterol inhalers used to be powered by CFCs (chlorofluorocarbons). Because of the Montreal Protocol to phase out the use and production of CFCs, since 2008 all Albuterol inhalers are powered by hydrofluoroalkanes (HFAs).
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.
What does chlorofluorocarbons destroy?
Chlorofluorocarbons destroy ozone. It is vital for earth.
What has had the greatest effect on ozone depletion?
Chlorofluorocarbons (CFCs)
How can you help lower the chlorofluorocarbons used?
CFC's cannot be destroyed. We have to just minimize their use.
Why is it important to use the placebo in the phase 3 trial?
so that you can compare the results with the real medicine.
What were chlorofluorocarbons first used as a refrigerant?
In the 1930s General Motors' Frigidaire company developed the first use of chlorofluorocarbons as a refrigerant. This technology became the standard for decades and essentially eliminated the danger of fire and poisoning
How did the aerosol can change over time?
They use hydrocarbons now; they used to use chlorofluorocarbons (CFC's) which were damaging to the ozone layer.
