What are some features of mercury?

Since mercury can mean either the element mercury or the planet mercury and since the question does not specify element or planet, I will give an answer to both.


Mercury (element):


Mercury is a metal and has an atomic number of 80 and a atomic mass of 200.6 amu. It is the only metal that is liquid at room temperature; all the other metals are solid at room temperature. One of the key features of...

Since mercury can mean either the element mercury or the planet mercury and since the question does not specify element or planet, I will give an answer to both.


Mercury (element):


Mercury is a metal and has an atomic number of 80 and a atomic mass of 200.6 amu. It is the only metal that is liquid at room temperature; all the other metals are solid at room temperature. One of the key features of mercury is its density, which is about 13.6 gram per ml. In other words, mercury has a specific gravity (the ratio of density to that of a standard liquid, generally water). We can also state that it is 13.6 times heavier than water. It is this property (specific gravity) that makes mercury useful in manometers and barometers for pressure measurement. Mercury is also commonly used in thermometers, although nowadays we prefer mercury-less thermometers. Mercury is a toxic element.


Mercury (planet):


Mercury is one of the planets in our solar system. In fact, Mercury is the closest planet to the sun. Mercury is also one of only two planets (the other being Venus) that does not have a natural satellite or moon of its own. All the other planets of our solar system have moons. Mercury is also the smallest of the 8 planets and takes the least amount of time to complete 1 revolution around the sun. 


Hope this helps.

What are some external and internal conflicts that Montag has in Fahrenheit 451?

 Montag, the protagonist of Fahrenheit 451, faces both external and internal conflicts throughout the novel. Some examples of these conflicts are: External Conflicts: Conflict with the society: Montag lives in a society that prohibits books and critical thinking. He faces opposition from the government and the people who enforce this law. Montag struggles to come to terms with the fact that his society is based on censorship and control. Conflict with his wife: Montag's wife, Mildred, is completely absorbed in the shallow and meaningless entertainment provided by the government. Montag's growing dissatisfaction with his marriage adds to his external conflict. Conflict with the fire captain: Montag's superior, Captain Beatty, is the personification of the oppressive regime that Montag is fighting against. Montag's struggle against Beatty represents his external conflict with the government. Internal Conflicts: Conflict with his own beliefs: Montag, at the beginning of th...

In A People's History of the United States, why does Howard Zinn feel that Wilson made a flimsy argument for entering World War I?

"War is the health of the state," the radical writer Randolph Bourne said, in the midst of the First World War. Indeed, as the nations of Europe went to war in 1914, the governments flourished, patriotism bloomed, class struggle was stilled, and young men died in frightful numbers on the battlefields-often for a hundred yards of land, a line of trenches. -- Chapter 14, Page 350, A People's History of the United States Howard Zinn outlines his arguments for why World War I was fought in the opening paragraph of Chapter 14 (referenced above). The nationalism that was created by the Great War benefited the elite political and financial leadership of the various countries involved. Socialism, which was gaining momentum in Europe, as was class struggle, took a backseat to mobilizing for war. Zinn believes that World War I was fought for the gain of the industrial capitalists of Europe in a competition for capital and resources. He states that humanity itself was punished by t...
