Define a near-azeotropic refrigerant blend and give two examples.?
a blended refrigerant with less than 10F temperature glide, 41oA and 404A are examples.
Does isopropyl give off a strong smell similar to nail varnish remover or surgical spirit?
Isopropyl alcohol does, indeed, give off a fairly strong odor as it evaporates... but airing the place out would rectify this. The odor would be gone fairly quickly as isopropanol evaporates pretty fast. This odor isn't like nail polish remover, which is primarily acetone.
When a solution evaporates what may be left behind?
crystallized solute
What are the advantages and disadvantages of acetic acid citric acid and sulfamic acid to descale And can you give sources please?
The advantages of sulfamic acid is it won't ruin anything you are descaling as opposed to acetic acid, which evaporates what you are descaling. On the other hand citric acid is weaker than the other two.
How does the refrigarator or freezer work to keep things cold?
Refrigerators, freezers, air conditioners, heat pumps(air and ground source) all work on the principles of refrigeration. Modern refrigerators don't use Chlorofluorocarbons because CFCs are harmful to the atmospheric ozone layer when released. Instead they use various other refrigerants that are now primarily Hydrofluorocarbons. In new refrigerators a gas called HFC-134a, also called tetrafluoroethane is used. HFC-134a turns into a liquid when it is cooled to -15.9 degrees Fahrenheit (-26.6 degrees Celsius). A motor and compressor squeezes the gas (refrigerant). When it is compressed, a gas heats up as it is pressurized. When you pass the compressed gas through the coils on the back or bottom of a modern refrigerator, the warmer gas can lose its heat to the air in the room. According to the laws of thermodynamics: 1) As it cools, the refrigerant will change into a liquid when it is under enough high pressure. 2) Something that is hot will give up its heat to its colder surroundings. The liquid flows through what's called an expansion valve, a small hole that regulates how fast the liquid refrigerant squeezes through. Between the valve and the compressor, there is a low-pressure area because the compressor is pulling the gas out of that side (while compressing it on the other). When the liquid HFC hits a low pressure area it boils and changes into a gas. This is called vaporizing. Remember that the refrigerant boils (or vaporizes) at minus 15.9 degrees F. That is always going to be colder than the surrounding air temperature in the fridge and even the freezer. Therefore, as the refrigerant within the coils (evaporator) passes through the freezer and regular part of the refrigerator, the colder liquid in the coils pulls the heat out of the compartments. This makes the inside of the freezer and entire refrigerator cold. The compressor sucks up the cold gas, and the gas goes back to the compressor to start the process over. A thermostat regulates when the desired temperatures in the cold compartments have been reached by turning the compressor on or off.
Will a steam burn give off a large amount of heat as it condenses?
the steam will give off a large amount of heat as it condenses.
When the gas condenses to liquid does it absorb or give off heat?
absorb
What does animals give to the water cycle?
Animals give off co2 or carbon dioxide when they die and decompose into the soil. From there, rain washes through the soil and then after a while vaporizes and emits co2 into the air.
Why does your refrigerator give off so much heat?
The compressor compresses the refrigerant gas. This raises the refrigerant's pressure and temperature, so the heat-exchanging coils outside the refrigerator allow the refrigerant to dissipate the heat of pressurization.
Define a near-azeotropic refrigerant blend and give two examples.?
a blended refrigerant with less than 10F temperature glide, 41oA and 404A are examples.
What is the water cycle in the tundra?
The water cycle in a tundra is that when the plants give out water it evaporates then it snows.
When did VW start using R-134a refrigerant?
please give me pressure knowledge for refrigerator
Will evaporating the water quickly give big crystal's or will it be better to do it slowly?
the slower something evaporates the larger the crystals
Name of acid formed when sulfur oxides mixes with rainwater?
I think it is Nitrogen Oxide. The nitrous oxide condenses with the rain to give the nitric acid, sulfur dioxide condenses with the rain to give sulfuric acid, carbon dioxide combines with the rain to give carbonic acid . These three acids constitute the acid rain.
What does a plant give to a water cycle?
through transpiration water is lost to the environment and condenses to fall as rain and is again absorbed as by the plant root.
Where is the low pressure valve for adding AC refrigerant on a 1999 Mercedes E430?

What is they water cycle?
first,water empties into the ocean then,the water rises and evaporates last,the clouds take in the air and give preporation
