Reactor cooling water is potentially contaminated with radioactive elements and you don't want those to be released into the environment, so it is kept in the primary loop.
Cold ethanol is most likely used instead of room temperature ethanol in order to prevent the ethanol from evaporating. When the temperature of something decreases the molecules speed decreases as well making it less likely to evaporate.
Yes, it can be brought back to solid by cooling. Because butter has only changed its state, which is a type of physical change. But some substances solids change their chemical composition instead of changing to liquid form, like Sugar. Sugar on heating turns red then black. Sugar cannot be brought back to its white solid form by cooling.
There seems to be a misunderstanding, "miles" is not a unit of measurement for NaOH concentration. If you meant molarity instead of miles, you need the molarity of NaOH in order to calculate the moles of NaOH in the given volume which can be converted to miles using the molar mass of NaOH.
When water and isopropyl alcohol react, they do not undergo a chemical reaction. Instead, they mix together to form a homogeneous solution. This is because both water and isopropyl alcohol are polar molecules, allowing them to dissolve in each other.
Granulated zinc is used instead of a block as the surface area of granulated zinc is much more than that of a block. Hence it's easier for it to react with oxygen if the area is more. This is why it's used.
Is the question how to bleed a Buick 3800 cooling system? I would say open that little petcock by the themostat housing and release all the air as you fill the system with coolant. When coolant comes out instead of air all the air is out.
to increase the waters boiling point
What ?????????????
Yes. The best to use is of course is a mixture of water and coolant but just water will work fine in your vehicle. Add coolant when you can get some for the best cooling. But only temporarily in an emergency. Water alone was fine (when the temperature stayed above freezing) back in the 1950s, but today's engines need the rust inhibitors and other additives.
There is no cap on the radiator; instead, the coolant reservoir is pressurized along with the rest of the cooling system. Look on the passenger side, under the hood. You should see the windshield washer reservoir AND the coolant reservoir. Be careful with the lid of the coolant reservoir. If the engine is hot, it will blow off in your face.
To bleed the cooling system on a 1996 Olds Cutlass, locate the bleed valve, which is on the front of the engine above the water pump. After making sure the cooling system is not under pressure, open the valve by turning it counterclockwise. Fill the radiator with coolant until no air comes out the bleed valve, and a stream of coolant begins to flow from there instead. Tighten the valve and close the system to finish the job.
I would only put water in an emergency situation where I don't have coolant available. The coolant helps the engine to not overheat and to not freezing, while that could happen if you just use water. If you don't have your vehicle's manual to know the specification of the coolant, you can use the generally available Prestone and add water according to the table on the coolant's recipient. (or you can buy the pre-mixed formula)
Engine coolant is formulated to withstand a greater range of temperatures. Not only will it prevent freezing, but in hot weather it raises the boiling point to about 260° F, where pure water would boil at 212° F. The cooling properties are better and it doesn't rust or cause rust.
Most 2003 Escapes will have the yellow 5year/100,000 mile coolant(instead of the green 3 year/50,000 mile). (from http://www.escape-central.com/2003_Ford_Escape.htm) CAUTION: Vehicle cooling systems are filled with Motorcraft Premium Gold Engine. Coolant VC-7-A (in Oregon VC-7-B) or equivalent meeting Ford specification WSS-M97B51-A1 (yellow color). Always fill the cooling system with the same coolant that is present in the system. Do not mix coolant types. (from "General Procedures 303-03-2" http://www.justanswer.com/uploads/kennyz1963/2008-04-26_082220_cooling.pdf)
The summer cooling effect is when the summer cools an area down instead of making it hot.
Water is coolant!!! Pre mixed coolant comes with anti freeze and sometimes a rust inhibitor, other than that it does same job. Common sense being your guide. Do not use straight water during the winter. Varying ratios of water mixed to antifreeze will actually increase the boiling point in both winter and summer and is more benficial in summer in terms of cooling function. More Coolant/antifreeze less water (mixed) increases boiling point correspondingly. It is of greater benfit to use coolant/antifreeze in your engine because it prevents rust and corrosion in the various parts of cooling system and heating system (heater) and increases the boiling point. Check the coolant/antifreeze container for instructions on mixtures and learn from it.
yes a core plug is a metal disc in the engine block about the size of a 50p coin these are meant to be a weak spot in the cooling jacket of the engine and in theory will give way if the coolant freezes instead of cracking the engine block
