Why the brass need to be immersed in the boiling water before place it in the calorimeter?

The brass needs to be immersed in the boiling water for a sufficient enough time that its temperature is the same as the boiling water, 100 degrees Celsius. That will be the initial temperature of the brass. After it is quickly placed in the calorimeter which will contain much cooler water, causing the brass to cool down and the water to heat up until the point where the temperature no longer changes. At that point the temperature of the brass is the same temperature as the water in the calorimeter, which is its final temperature of the brass.

Was bronze discovered before brass?
Bronze was probably alloyed before brass, yes. Bronze is copper and tin. Brass is copper and zinc. Bronze is the alloy most commonly found in ancient tools. But native copper itself was discovered before the alloys were.
Is brass very ductile?
Some brass alloys are very ductile, provided they are annealed before forming; others not so.
What makes a brass a brass?
Brass makes Brass instruments for example, the Tuba, trumpet, euphonium,and trombone are ALL made of brass
Why is brass a heterogeneous mixture?
No. Brass is a homogeneous mixture.
Is a brass screw a pure substance?
No. Brass is an alloy of copper and zinc.
What is The boiling point of Brass Celsius?
906 degrees
Boiling point for brass?
57869 degrees centigrade :)

Better defenitions exist, but this one works: Long Brass wailing, immersed in tears. It works even when the instrument is stringed.

What type of musical group was the forerunner of the jazz bands that develpoed in new Orleans in the late 1800s and early 1900s?
Brass bands were a popular band before that.
What is the melting and the boiling point of brass in degrees Celsius and Fahrenheit and kelvin?
Brass consists of copper and zinc ordinary yellow brass, 67% - 33% respectively, MP= 940C, 1213K, 1724F ordinary red brass, 90% - 10% resp., MP= 1050C, 1323K, 1922F other forms are in between. The boiling point, initially is assumed Zinc boiling point, 907C, 1180K, 1665F However as it is hard to expect BP below MP, then I would say the BP of brass is very near its MP, in other words, Zinc vapor exists in parallel with liquid brass. final boiling point is assumed Copper boiling point, 2336C, 2609K, 4237F

What are the three properties of mixture?
1) There is no fixed composition in mixtures. Eg. Copper and tin are mixed together in variable ratios to form brass. Therefore, it is a mixture. 2) Mixtures do not have a fixed boiling point. This is due to the varying composition of its constituents. Its different constituents have different boiling points, therefore resulting in its unfixed boiling point. 3) Mixtures do not have a fixed boiling point. The reason is similar to the reason given for its unfixed boiling points. Hope this helps (: -babyhamsterx
Which instrument does not have values to change notes?
The brass instruments did not have valves before the Romantic period. Therefore, those were not chromatic instruments approximately before 1800's. Compare lines for brass instruments in Chopin's music with that of Mozart which proves the fact.
What was the French horn originalaly made from?
In the form it is currently in, brass... if you want to go back to before the horn was a horn, then copper.. bone... same as any other brass instrument.
What family of instruments does a tuba belong to?
