But‚ after his wife passes away he feels empty and becomes convinced that Death is now after him too. He hears strange voices in his head‚ mimicking his own words‚ but they are phony and ridicule him in every possible manner. Comparing

    The pressure of time is crucial in both works‚ as both narrators race against time to save themselves or others. In the Pit and the Pendulum‚ the narrator is strapped to a strange contraption‚ with a deadly pendulum descending towards him. The pendulum is lowering an unhurried rate as it states in the article‚ "It might have been half an hour‚ perhaps even an hour‚ (for in cast my I could take but imperfect note of time) before I again cast my eyes upward. What I then saw confounded and amazed me

    December 29‚ 1890 near Wounded Knee Creek‚ in South Dakota. Both‚ the New York Times and the London Times have published articles on this event. However‚ their interpretations of the event are quite different. It is interesting how the same event can be portrayed in two completely contrasting ways. Specifically‚ the New York Times justifies the American’s actions towards the Native Americans‚ whereas the London Times portrays the American’s actions as unacceptable towards the Native Americans.

    the rate of reaction between potassium permanganate with oxalic acid. We used 2cm3 of 0.02M potassium permanganate and 4cm3 of 1M sulphuric acid into a test tube. In another test tube‚ we placed 2cm3 of oxalic acid. We placed the test tubes in a water bath at 40‚ 45‚ 50‚ 55 and 60oC respectively. When the solutions have attained these temperatures pour the oxalic acid into the acidified permanganate solution and recorded the time taken for the permanganate to decolorize. At 400C ‚ the time taken for

    WHAT IS TIME AND WHAT CAUSES TIME? Australian writer and physicist Paul Davis has called time Einstein’s unfinished revolution. Einstein was first to introduce the concept of slowing of time with motion and in gravity. He was also a proponent of block universe view of time in which past present and future all coexist together laid out as a dimension on a time line. The Greek philosopher Aristotle had speculated that time may be related to motion; he however

    RATE OF REACTIONS. The reaction rate (rate of reaction) or speed of reaction for a reactant or product in a particular reaction is intuitively defined as how fast or slow a reaction takes place. For example‚ the oxidative rusting of iron under the atmosphere is a slow reaction that can take many years‚ but the combustion of cellulose in a fire is a reaction that takes place in fractions of a second (right). Chemical kinetics is the part of physical chemistry that studies reaction rates. The concepts
