testing. What do all of these things have in common? They are all services the Tory government in Ontario has been trying to privatize with some disastrous results and possibly more to come. The Ontario government‚ lead by Progressive Conservative leader Mike Harris‚ has been slowly trying to do away with services that are currently administered by the province. The ideology in question‚ privatization‚ has been a hallmark of the Common Sense revolution. But so far the Tories have been slow to make a success

Experiment to measure the latent heat of vaporisation of water Theory Latent heat of vaporisation is when a liquid is heated enough to start boiling‚ at this point‚ even if the source of heat keeps heating the liquid‚ the liquid’s temperature will not rise any further until all of the liquid is converted to gas. For example‚ if water is boiling in a kettle‚ and the kettle is left on whist the water is boiling‚ the water’s temperature will not exceed 100°C because all the heat energy from the kettle is

Heats of Reaction Lab Report Purpose: To measure the heats of reaction for three related exothermic reactions and to verify Hess’s Law of Heat Summation. NaOH(s) ( Na+(aq) + OH-(aq) ΔH = -10.6kcal/mol NaOH(s) + H+(aq) + Cl-(aq) ( H2O + Na+(aq) + Cl-(aq) ΔH = -23.9kcal/mol Na+(aq) + OH-(aq) + H+(aq) + Cl-(aq) ( H2O + Na+(aq) + Cl-(aq) ΔH = -13.3kcal/mol Background: Energy changes occur in all chemical reactions; energy is either absorbed or released. If energy is released in

In his essay‚ “I Just Wanna Be Average‚” author Mike Rose says‚ “students will float to the mark you set” (164). From my past experiences‚ I completely agree that students will work harder if their teachers set the standards high. Generally‚ teenagers do not have high goals or standards for themselves‚ so it is up to the teachers to encourage and push the students towards success. Throughout his excerpt‚ Rose shows through numerous examples that teachers are a vital part to a student’s success

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

In the story‚ "I Just Wanna Be Average" the main character‚ Mike Rose‚ takes us through his years at Mercy High School during the 1960’s and 1970s. Although many people appear in this story‚ the main people are Ted Richard‚ Ken Harvey and Mr. Macfarland. Ted Richards was a bit of a dream‚ turning his back on the real world and just let his mind roam. Ted was always laughing‚ his loud and jolly voice booming out. Even when he’d get angry‚ he’d give a little smile. Ken Harvey became a central figure
