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

CRITICALLY EVALUATE THE FACTORS INFLUENCING THE GLOBAL HEAT BUDGET - 40 MARKS The global heat budget is the balance between incoming insolation‚ and outgoing radiation from Earth. There are many factors that influence this heat budget‚ some of which are more important than others. In this essay I am going to describe and explain each factor involved. Insolation is the incoming energy from the sun in shortwave ultraviolet (UV) radiation. The distribution of insolation over the Earth’s surface

Heat Treatment and Qualitative Metallographic Analysis Lab ME 3228: Mechanics & Materials Laboratory Summary Comparing a material’s initial treatment and the microstructures that are formed from different processes‚ an engineer can accurately understand why certain treated materials of the same family can be stronger than another. In this experiment annealed and cold-worked specimens of AISI 1018 STEEL are used‚ along with a Hardness tester‚ a grinding and polishing process‚ and a micrograph

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
