How does heat effect pH level?
Heating pure water the pH decrease.
Can the hydrogen and oxygen created by the electrolysis of water be easily recombined to create pure water?
Yes, the pair of gases can easily be combined to create pure water. Passing the two gasses across a hot surface will cause the hydrogen and oxygen to "burn" or recombine, and (pure) water will form. The water will appear as a hot gas, but cooling it will cause it to condense.
How does the time temperature cooling curve of an alloy of eutectic composition different from that of a pure metal?
Usually with a pure element, you only have atoms of that element, example element C. So whatever the phase may be (eg. solid or liquid), the composition will only consist of the C atoms. An alloy on the other hand has more than one composition. For this example, lets say that the alloy consists of element A and B. Both the pure elements and the alloy have different phases they can be in, but the alloy's phases will consist of A + B. If the metals were to be heated up and cooled down, looking at a phase diagram you would see the different phases the alloy and the pure metals are in at that particular temperature. Looking at a phase diagram steel as an example, alloy of Iron and Carbon, with say a .05 wt % carbon, you can heat it up past 910 degrees C to austenitize the alloy reaching the Austenite phase. Then following straight down the phase diagram you will see the different phases the steel achieves. With TTT curve, however, time is another variable to consider. The steel can be austenitized and rapidly quenched to a certain temperature and held at that temperature yielding a certain microstructure due to the phase it is held at. Long story short, TTT curve most likely applies to alloys, particularly steel, whose time dependence shape the microstructure. Most likely you won't find a TTT curve for a pure element because the microstructure will not be too affected by heat treatment.
Which is a poor conductor tap water or pure water?
Pure water is a poor conductor of electricity because of the lack of ions. You need ions (electrically charged particles) to propagate the charge through the water. Both tap and pure water are poor conductors of heat.
How do cooling curves provide evidence for pure and impure substances?
Cooling curves illustrate how a substance changes temperature over time as it cools. For pure substances, the cooling curve shows distinct horizontal plateaus during phase changes (like melting and freezing), indicating a consistent temperature during these transitions. In contrast, impure substances exhibit irregular cooling curves with no defined plateaus, reflecting a range of melting points due to the presence of multiple components. This difference helps identify the purity of a substance based on its thermal behavior.
What is cooling curve for pure metals?
A cooling curve for pure metals shows the changes in temperature as a molten metal solidifies. It typically consists of a gradual decrease in temperature until the metal solidifies, followed by a period where the temperature remains constant as the latent heat of fusion is released, before the temperature decreases further. The cooling curve can provide important information about the solidification process and the resulting microstructure of the solid metal.
What is the demand curve faced by a pure monopolist?
The demand curve faced by a pure monopolist is of downward sloping in shape.
Do pure substances cool quicker than non pure substances For example pure water and salty water?
The impurity of a substance may enhance or decrease the rate of cooling, according to its chemical properties.
Why does sea water have a different boiling point than pure water?
because of the heat in the water
The nondiscriminating pure monopolist's demand curve is the industry demand curve.?
yes
Can you drive a car with only water in the radiator?
Yes, you can. In fact, pure water is a more effective coolant than any mixture of water and antifreeze. However, it is not recommended that you run pure water in a cooling system for an extended length of time. Not only does antifreeze protect against freezing. It also contains corrosion inhibiters, which help prevent your engine and radiator from succumbing to corrosion. For these reasons, using only water in your cooling system is something you should do only when you have no choice (such as a roadside emergency). However, if pure water is used in a cooling system for this reason, the cooling system should be drained ASAP and refilled with the proper mixture of antifreeze and water.
How do you turn salt water to pure water?
Distillation is the easiest way. Heat the water until it evaporates, leaving the salt behind. Catch and condense the water vapor into pure water.
Is water magnetic does it conduct heat and sound and electricity?
Pure water is NOT magnetic, a poor conductor of electricity, but good in sound and heat.
Specific heat of pure water?
4.18 J/g*C
Does water hold more heat energy than pure or drinking alcohol?
Water has a higher specific heat capacity compared to pure or drinking alcohol. This means that water can hold more heat energy per unit mass. Therefore, water can absorb and retain more heat energy compared to alcohol.
How does heat effect pH level?
Heating pure water the pH decrease.
Can the hydrogen and oxygen created by the electrolysis of water be easily recombined to create pure water?
Yes, the pair of gases can easily be combined to create pure water. Passing the two gasses across a hot surface will cause the hydrogen and oxygen to "burn" or recombine, and (pure) water will form. The water will appear as a hot gas, but cooling it will cause it to condense.
