Is using hot water to expand a metal cup a physical or chemical change?
Using hot water to expand a metal cup is a physical change. The change in size and shape of the cup is due to the expansion of the metal atoms when heated, but the chemical composition of the metal cup remains the same.
How do you test a filtrate without using water?
To test a filtrate without using water, you can conduct qualitative analysis tests such as flame tests, chemical reagents tests, or spectroscopic analysis. These tests can provide information about the composition of the filtrate without the need for additional water.
What is the procedure to identify metals?
One common procedure to identify metals is through a flame test, where the metal sample is heated in a flame and the characteristic color of the flame produced can help identify the metal. Other methods include using reactivity with acids or other chemicals, measuring density, conducting an electrical conductivity test, or using spectroscopic techniques to analyze the metal's atomic structure.
Does flame cutting use a neutral flame or slightly oxidizing flame?
Assuming that you are using the Oxygen-Acetylene cutting process; both, depending at what stage/phase of the cutting process you are in. What we encounter is a gas flow differential problem. With the cutting torch flame properly adjusted (the acetylene valve opened to the point where the un-mixed acetylene flame is burning without producing any smoke but still in contact with the cutting tip of the torch, the oxygen valve is slowly opened until you have adjusted the flame to a neutral quality or setting. Press the cutting oxygen lever; typically the flame will become slightly carburizing ("feathers" will appear at the ends of the pre-heat flames) this phenomonom occurs because of the drop in line pressure due to the high flow of oxygen through the cutting tube or orifice. With the oxygen lever remaining depressed, readjust the flame to a neutral setting. This will cause the flame to become slightly oxidizing when the cutting lever is released; since an oxidizing flame burns slightly hotter than a neutral flame the pre-heat of the metal that is being cut is faster. When the metal is at the proper pre-heat or kindling temperature (1600 F for pure iron - various steel alloys will be slightly different; beginning to turn bright red is a good indicator) depress the cutting oxygen lever, the flame will revert to "neutral" and the cut can then begin. Weld. Prof.
How can i make a match stick burn without rubing it?
You can light a match stick using another match stick, a lighter, or a candle. Simply expose the match head to the flame to ignite it.

How can wood be attached to metal without using screws?
Wood can be attached to metal without using screws by using methods such as welding, adhesive bonding, or using specialized fasteners like metal clips or brackets.
Is using hot water to expand a metal cup a physical or chemical change?
Using hot water to expand a metal cup is a physical change. The change in size and shape of the cup is due to the expansion of the metal atoms when heated, but the chemical composition of the metal cup remains the same.
What ways can you light a match without using flame or friction?
With the sun... *smile* and a loupe.
Why is it necessary to use non-luminous flame in flame test?
Using a non-luminous flame in a flame test ensures that the color produced is due to the metal ion itself and not any additional color from the burning fuel. This allows for accurate identification of the metal ions present in the sample based on the specific color produced in the flame.
How can a hole be made in metal without using a drill?
A hole can be made in metal without using a drill by using methods such as punching, laser cutting, or plasma cutting. These techniques involve applying force or heat to create a hole in the metal.
How can wood be burned without using a torch?
Wood can be burned without using a torch by using a match or lighter to ignite it. The heat from the flame will start the combustion process, causing the wood to burn.
How can I effectively loosen a rusted bolt without using WD-40?
One effective way to loosen a rusted bolt without using WD-40 is to apply heat to the bolt using a blowtorch or a heat gun. The heat helps to expand the metal, making it easier to break the rust seal. Be sure to use caution and wear protective gear when using heat to avoid injury.
Why do you use hot water to open the metal lid of a jar?
Using hot water to open a metal jar lid helps to expand the metal, making it easier to twist open the jar. The heat from the hot water causes the metal to expand while the glass of the jar remains relatively unaffected, creating a temperature difference that helps to loosen the lid.
How can metal be rusted without using hydrogen peroxide?
Metal can be rusted through a process called oxidation, which occurs when the metal comes into contact with oxygen and moisture in the air. This causes the metal to corrode and form rust, even without the use of hydrogen peroxide.
How do you unlock metal Mario on super smash bros on the Nintendo 64 without using a gameshark?
You cant, there is no playable character as Metal Mario.
How do you test a filtrate without using water?
To test a filtrate without using water, you can conduct qualitative analysis tests such as flame tests, chemical reagents tests, or spectroscopic analysis. These tests can provide information about the composition of the filtrate without the need for additional water.
