Not wanting to kill him the people placing the rocks go slowly trying to get answers from him, but at any moment they ask him to confess he says: “More Weight.”. This shows mass hysteria because once word got out about witchcraft people began accusing and accusing, the definition of hysteria is “Exaggerated or uncontrollable emotion or excitement, especially among a group of people.”, in which the keyword is “exaggerated”, everyone feels that if everyone else begins to accuse others of something they most likely didn’t do, then they should follow along with the group.

) Suppose that some magnesium oxide smoke had escaped during the investigation, the Mg:O ratio would have increased from 58% to 72%. The final mass of MgO would have decreased because the magnesium oxide smoke is part of the product and when some of it escapes, it decreases the final mass.

A crucible is defined as a container made of a heat-resistant substance in which metals may be melted, or a severe test or trial. In the 1953 play, The Crucible by Arthur Miller, the people of Salem, Massachusetts were put through a severe test during the witchcraft trials.

The purpose of this lab was to test the law of definite proportions for the synthesis reaction of combusting magnesium. In this lab, the polished magnesium ribbon was placed in covered crucible and was heated in order for it to react with Oxygen presented in air and in water provided. The result showed that Magnesium oxide formed through chemical reaction was made up of 60.19% magnesium and 39.81% oxygen, which is approximate proportion of both particles in every Magnesium oxide compound. From this lab it can be concluded that the law of definite proportion stating that the elements in a pure compound combine in definite proportion to each other is factual.

A ‘crucible’ is an object in which substances are combined and then subjected to high temperatures. Arthur Miller uses this theme to guide “The Crucible” from the exposition, when Puritan girls danced in the woods, to Proctor’s death by the hangman’s noose. Hale and Danforth are closely intertwined in their beliefs and views at the beginning of the play, but, as tensions and temperatures rise, they begin to separate; ultimately ending with contrary beliefs. In the opening scenes, Hale and Danforth are present in Salem, Massachusetts in 1692 to cast out demons and witches. When the final curtain falls at the end of Act Four, Hale recognizes that the Salem Witch Trials were a result of repressed emotions and conflicts, and the desire to express them under the pretext of witchcraft. Danforth cannot and will not recognize this fact. Thus, Miller develops the characters of Hale and Danforth into foils for each other by the end of the novel; the growing tension is made evident through dialogue, character development, and through the theme of pride.
