Sport Research Project Ice Hockey I. History Around 1820 the sport started to catch on among the visitors to the frozen lakes. People had played field hockey and another game in Europe for years‚ but this new version of the old sport required that it’s players put on skates. Using metal blades that could be strapped to their boots‚ the players would cut branches from trees to use as sticks; for pucks they would use round pieces of cork or wooden balls. In the 1870s‚ each team was made

of aluminium‚ a room temperature block of plastic‚ and an ice cube. This is all you need for a simple experiment with a seemingly obvious result. The ice will melt quickly on plastic and stay cold on the aluminium just like it does in a metal water bottle you think to yourself‚ but the answer is not that transparent. In actuality‚ the second that the ice hits the aluminium it melts instantly as if it was never a solid to begin with. The ice sits peacefully on the plastic with no change to the state

after finishing an ice cold drink on a hot day that the ice had altered itself into water? Water is actually made up of lots of tiny particles. These tiny particles move around in water when it is in its liquid form‚ but as the temperature gets lower these particles slow down and hardly move. When it gets cold enough they stick together and then what was once a liquid has now became a solid we all know as ice. Ice turns into water‚ back to a liquid‚ when the temperature of the ice cube is rising which

“Chronicles of Ice” by Gretel Ehrlich “Why did we trade in our ceremonial lives for the workplace? Is this a natural progression or a hiccup in human civilization that we’ll soon renounce” (Ehrlich 91)? Gretel Ehrlich asks these deep questions in her short informative essay “Chronicles of Ice” (2004). Ehrlich tells of her travels to The World Heritage glacier Perito Moreno‚ Argentina. In this short narrative‚ the author uses pathos and strong human related metaphors‚ to relay the direct correlation

is quantified in calorimetry by a device called calorimeter. There are two types of calorimeters. The first type is the called the bomb calorimeter. It is ideally suited for measuring the heat evolved in a combustion reaction. Because the bomb confines the reaction mixture to a fixed volume‚ the reaction is said to occur at constant volume. The other‚ much simpler and the calorimeter you are most likely to encounter is the coffee-cup calorimeter. This uses Styrofoam‚ a good heat insulator‚ for

Thermochemistry: An Ice Calorimeter Determination of Reaction Enthalpy Curtis M. Franklin Thursday‚ February 14‚ 2013 ABSTRACT An ice calorimetric measurement was used to determine that a reaction involving solid magnesium metal and 1.00M sulfuric acid produces an experimental a value of ∆H = -226 ± 28 kJ/mol at 0°C. This is about 48.4% lower than the expected value reported at 25°C. Introduction Many chemical reactions exhibit themselves by exchanging heat energy‚ either be absorbing

Thermochemistry: An Ice Calorimeter Determination of Reaction Enthalpy Shannon Wedepohl 9/17/13 Abstract: During this experiment‚ an ice calorimeter was used to measure the change in volume in milliliters of magnesium metal and 1.00 M of sulfuric acid. We found the experimental molar enthalpy of the reaction to be ∆H = -370 ± 1 kJ/mol at 0˚C. This compares with an expected value of -466.9 kJ/mol at 25 ˚C‚ a 20.75% difference. Introduction: Many chemical reactions truly only

My 48 hour ice cube addiction simulation turned out to be very different than what i had expected. I don’t put an ice cubes in my water cup at all. So my ice maker in the freezer is always empty. So I have to keep the ice maker full of ice cubes to use it in my addiction simulation. My first hour in the 48 hours simulation I was trying to fill my water bottle with ice cubes. I spilled some of ice cubes on the floor. My dad got suspicious when I filled a water bottle full of ice cubes‚ because I’m
