Is using hot water to expand a metal cup a physical or chemical change?
Physical- the metal isn't changing. If you burned it, then perhaps it would be chemical. But it's physical.
Why do you have to use the yellow flame when not using the Bunsen burner?
You don't have to use the yellow flame but its not recommended for heating as its a lot cooler than the blue flame.
When using a Bunsen burner why do you use the blue flame for heating?
The blue flame is hotter then the orange one. Plus the temperature of the flame is not constant in a orange flame but it is more constant in a blue one.
What is metal craft?
metal craft is using metal
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 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.
Why do you use the blue flame while using a Bunsen burner?
hottest part of flame
What is a sentence using the word flame?
The flame of the candle was placed too close to the centerpiece.
How do you clean big hoop earrings without tarnishing the metal?
The best way to clean earrings with out tarnishing the metal is by using rubbing alcohol. This will not only clean the earrings, but it also works as a disinfectant. Rubbing alcohol does all this without tarnishing the metal.
How do you expand multinomials?
One way to expand multinomials is using Pascal's triangle.
How do you get Metal Sonic without getting All the emblems?
You can't. At least, not without using a cheating device like a Gameshark or an Action Replay.
Why do you have to use the yellow flame when not using the Bunsen burner?
You don't have to use the yellow flame but its not recommended for heating as its a lot cooler than the blue flame.
How does a flame sensor work in home furnaces by using a metal rod in the flame?
Its not a flamesensor its a pilot generater it generates a small amound of electricity to open the main valve that way if your pilot light goes out it wont let gas escape and couse a potentian explosion The above answer is not accurate unless you have a standing pilot model furnace. Then the "flame sensor is called a thermocouple, much different than the flame sensors used in Direct Spark Ignition, hot-surface and intermitant ignition furnaces. The flame sensor uses the flame of the main burner to prove flame at the circuit board by measuring conductivity to ground through the flame.
