How was the atmosphere discovered?
The discovery of Earth's atmosphere can be attributed to the development of early scientific observations and experiments, such as those by Robert Boyle and Isaac Newton in the 17th century. Through these investigations, scientists were able to understand the composition of gases surrounding the Earth and eventually define the concept of the atmosphere as a layer of gases held in place by Earth's gravity.
Can the atoms and of molecules of gases and liquids move from place to place?
Yes. They are able to flow.
Was Mendeleev's periodic table accurate enough that he was able to use it to predict the existence and several properties of certain elements that had not yet been discovered?
Mendeleev was able to predict the properties of the elements that were not discovered at that time. He left gaps for these elements in his Periodic Table.
Who discovered penciline?
Alexander Fleming discovered penicillin in 1928. He noticed that a mold called Penicillium notatum was able to kill bacteria, leading to the development of the first antibiotic.
What planet has a gravity so as to hold most gases?
Jupiter has the most gravity among all the planets in our solar system, and it is able to hold onto its massive atmosphere of gases, primarily hydrogen and helium. Its strong gravitational pull prevents these gases from escaping into space.
Why were gases that Ramsay discovered not able to be discovered any earlier?
These gases exist only in very low concentration and also are very unreactive.
What group was not been discovered during Mendeleev's time?
The zero group of noble gases was not discovered during Mendeleev's time. Sir William Ramsay was able to add them without disturbing the basic concept of the table.
How was the element neon discovered?
Neon was discovered in 1898 by Sir William Ramsay and Morris Travers through their experiments with liquefied air. They were able to isolate neon by fractional distillation of liquid air, which allowed them to separate the different components of air based on their boiling points. Neon was identified by its distinct reddish-orange glow when an electric current was passed through it, leading to its discovery as a new element.
Who discovered the element argon with Lord Rayleigh?
The element argon was discovered by Lord Rayleigh and Sir William Ramsay in 1894. They were able to isolate argon by removing all other gases from a sample of air, leading to the discovery of this new element.
How did Ramsay and Travers discover Xenon?
Ramsay and Travers discovered xenon in 1898 by fractionally distilling liquid air. By isolating and purifying the gas they were able to identify its unique spectral lines, leading to the discovery of a new element which they named xenon.
Why are gases useful to people?
so that you are able to breath

Why is coke able to flow?
maybe because the gases it contains
How was the Titanic sink located?
The Titanic was able to be discovered by the cordinates
Advantages of spiral model?
1. Estimates (i.e. budget, schedule, etc.) become more realistic as work progresses, because important issues are discovered earlier.2. It is more able to cope with the (nearly inevitable) changes that software development generally entails.3. Software engineers (who can get restless with protracted design processes) can get their hands in and start working on a project earlier.
Why Xenon gas forms compounds if it is a noble gas?
Noble gases are generally considered unreactive, due to the stability of their electron shells, and it was originally believed that they could not form compounds. It was later discovered that a very strong oxidizing agent though is able to form compounds with them.
What did Able Tasman invent?
nothing, Tasmania was named after him becoz he discovered it
