Can a Candle Burn in Zero Gravity

A candle can burn in zero gravity, but the flame is quite a bit different. Fire behaves differently in space and microgravity than on Earth. Microgravity Flames A microgravity flame forms a sphere surrounding the wick. Diffusion feeds the flame with oxygen and allows carbon dioxide to move away from the point of combustion, so the rate of burning is slowed. The flame of a candle burned in microgravity is an almost invisible blue, so invisible that video cameras on the Mir Space Station could not even detect the color. Experiments on Skylab and Mir indicate that the temperature of the flame is too low for the yellow color seen on Earth. Smoke and soot production are different for candles and other forms of fire in space or zero gravity compared to those on earth. Unless airflow is available, the slower gas exchange from diffusion can produce a soot-free flame. However, when burning stops at the tip of the flame, soot production begins. Soot and smoke production depend  on the fuel flow rate. It isnt true that candles burn for a shorter length of time in space. Dr. Shannon Lucid (Mir), found that candles that burn for 10 minutes or less on Earth produced a flame for up to 45 minutes. When the flame is extinguished, a white ball surrounding the candle tip remains, which may be a fog of flammable wax vapor.

Hhhhhh Essay Example For Students

Hhhhhh Essay hitchcockVertigo stars James Stewart as Scottie, a retired detective, and Kim Novak as Judy Barton, who gets disguised as Madeleine, a woman hired by Scotties friend to act as his wife in order to frame Scottie. The story takes place in San Francisco in the 1950s. The film opens on a high building, where officer Scottie and his partner are in pursuit of a suspect. Scotties partners life is on the line and only he can save him. Unfortunately, he has vertigo, a fear of heights. Scottie is unable to assist his partner who unfortunately falls to his death. Hitchcock underlines Scotties fear of heights by using intense music and a birds eye view of the street below, to give the viewer an impression of height. Closeups of Scotties face demonstrate his obsessive fear, hence making it more realistic to the audience. As the story develops, Scottie falls deeply in love with Madeleine, a beautiful young blonde woman. Madeleine later runs up the stairs of a church, unsuccessfully pursued by Scot tie, and jumps off the roof killing herself, or so Scottie thought. Here again, the camera angles play an important role in demonstrating Scotties fear of heights, as a spiralling effect is used to shoot the staircase. As the story develops, Scottie gets admitted to a psychiatric unit. His mental and emotional confusion is illustrated by chaotic music. When he meets a young woman named Judy Barton, who bears a striking resemblance to the late Madeleine, Hitch really takes advantage of color in a scene in Judys apartment. Fog, typical to San Francisco, combined with green light coming from a neon sign in the street, give the scene a remarkable, almost divine effect. In order for Scottie to overcome the trauma he suffered when he lost Madeleine, he drives Judy to the same church and asks her to run up the stairs in an attempt to reproduce the sequence of events leading up to Madeleines death. Shockingly, Judy really jumps off the roof, thus abruptly ending the story. An Internet revie w points out that the Vertigo script reads: There is a flower stand known to all San Franciscans at the curb opposite the main entrance to Gumps. Scottie and Judy have stopped there to pick a flower for her to wear Amazingly, this flower stand still exists, although it is no longer the wood frame structure as seen in the film, (its now made of black steel). Gumps has since moved one block down Post Street. (http://www.widescreencinema.com/vertigo/tour.htm) Vertigo has two characteristics common to many Hitchcock masterpieces: the presence of a young beautiful blonde woman, and the main characters weakness, in this case, Scotties vertigo. Like all of Hitchcocks movies, suspense is omni-present, and the story generates a strong reaction from every viewer. The abrupt ending makes the film stand out, and the complexity of the plot as well as the expressed values of love and passion, in addition to the themes of reality and tragedy, make this classic worthy of being on the list of the Top-100 movies of all time. According to critically acclaimed movie critic Martin Siberok, this is Hitchcock at his cynical best a story of human obsession and psychological instability, exploitation and guilt. Hitchs message in this movie is to face our fears in order to go on with our lives.
