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
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.
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 was the ingredient in aerosol cans that banned them from use?
chlorofluorocarbons (CFCs)
How can you use the word chlorofluorocarbons in a sentence?
Chlorofluorocarbons are thought to deteriorate the ozone.
What is the source chlorofluorocarbons?
Chlorofluorocarbons (CFCs) are synthetic compounds that were primarily used as refrigerants, solvents, and propellants in aerosol sprays. They were widely produced by humans for several decades before their harmful effects on the ozone layer were discovered, leading to international agreements to phase out their production.
Why is it important to use the placebo in the phase 3 trial?
so that you can compare the results with the real medicine.
Which chemical used in refrigeration system for destruction of ozone layer?
Chlorofluorocarbons (CFCs) were commonly used in refrigeration systems and were found to be destructive to the ozone layer. Efforts have been made to phase out the use of CFCs and replace them with more environmentally friendly alternatives.
What does chlorofluorocarbons destroy?
Chlorofluorocarbons destroy ozone. It is vital for earth.
How can you help lower the chlorofluorocarbons used?
CFC's cannot be destroyed. We have to just minimize their use.
How do you use a one phase motor in place of a three phase motor?
To use a single/one phase motor instead of a three phase motor is possible if you have a three phase power supply as you will only need to tap one of the three phases together with neutral and an earthwire, however to use a three phase motor instead of a single phase will require the provision of three phase power supply.
When is it appropriate to use a linear phase equalizer in audio processing?
A linear phase equalizer is appropriate to use in audio processing when maintaining the timing relationships between different frequencies is important, such as in situations where preserving the original sound quality and avoiding phase distortion are crucial.
