Vapor Pressure and Heat of Vaporization Introduction: Evaporation is the process of a liquid becoming vaporized. When a liquid is placed into a confined space some of the liquids will evaporate. Evaporation of the liquid depends on the strength of the intermolecular forces that are between liquid molecules. During the evaporation process of the liquid‚ new gas molecules exerts pressure in the sealed container‚ while some of the gas condenses back to the liquid state. If the temperature inside

The Effects of Heat on the pH of the Vegetable and Their Pigment PURPOSE The purpose of this experiment is to see how pH levels of certain vegetables change while being cooked in four different mediums (frying‚ boiling‚ steaming‚ roasting)‚ and how the varying pH levels change the coloring of the vegetables. We will analyze how the different method of cooking/heating changes the levels of pH. BACKGROUND INFORMATION This experiment is based around the different pigments in vegetables‚ of which

The gripping novel “In The Heat Of The Night” written by John Ball in 1965 is a story about a black man named Virgil Tibbs suspected to be a murderer when a crime takes place in the City of Wells. In the mid 60’s black people were accused guilty by the white people because they do not have equal rights with the white people. The story is also about racism which is very well-known at that time until now. The novel has been made into a movie in 1967. The main character was played by Sidney Poitier

Heart of Darkness vs. Secret Sharer Does Conrad base the character development in his stories on his own explorations? Based on the similarities of “The Secret Sharer” and “The Heart of Darkness”‚ yes. Conrad’s main characters are both young‚ non-tested men who are exposed to the uncivilized human nature. There is also another character that is allows an insight into the main characters life. A lot of change takes place inside these characters throughout the story. Conrad develops his main characters

Beat the heat with aircon repair Summer times can be difficult to manage in the hot regions and this calls for a nice chilled breeze of the air conditioner. While this may be the best prospect at this time‚ the problem comes with the appliance itself. Air conditioners just like any other electronic appliance are prone to problems and malfunctions. The malfunctions in this case can be quite bad considering how complicated the appliance is and this means that it requires professional help and not a
