The Theoretical Enthalpy Of Melting Ice

Decent Essays
The task of determining the amount of energy released as heat during the melting of ice into water was very organized. Learning how to do calorimetry calculations with a coffee cup and a lid was difficult at first because of the potential heat escaping from it, but once that obstacle was passed, the experiment carried out smoothly. The theoretical enthalpy of melting ice is +6.02 kJ/mol is somewhat half of the actual enthalpy that this experiment produced, +13.8 kj/mol.
Due to the errors, the result did not equal the theoretical value of melting ice, which was +6.02 kJ/mol. An error such as not letting all the ice melt may have affected the final temperature. Having a limited amount of time to do the experiment could also contribute to the

    What was the horsepower calculated? Does this make sense? The horsepower calculated when running up the stairs was 0.67 hp. This makes sense as 1 hp was originally defined to be the approximate amount of work a strong dray horse could do while lifting coal for one minute (The Editors of Encyclopædia Britannica, n.d).…

    The molar enthalpy of dehydration is not able to be determined in a one-step calorimetry experiment because the dissociation of ions occurs when the solution dissolves in water. Hess’s Law allows for the two thermochemical equations to be added resulting in a net equation, one that describes the molar enthalpy of dehydration. Calorimetry is using a tool, the calorimeter, which insulates the system from the environment. This allows for the changes of temperature to be observed with minimal heat loss to the environment. Calorimetry allows for the heat of the solution to be calculated since the heat capacity of the calorimeter is known and the change in temperature is observed.…

    “Miracle on Ice” On February 22, 1980 history was made. In the midst of the tensions between the United States and the Soviet Union, Team U.S.A managed to beat the U.S.S.R. team in a fierce hockey game during the XIII Winter Olympic Games. Due to the numerous American defeats throughout the entirety of the Cold War, ranging from the conflicts at Vietnam, the U2 incident, and the vast spread of communism, “The Miracle on Ice” boosted American morale towards the fight against the Soviet Union at a time when they needed it most.…

    Truc-Nhi Do Ice Cube Inquiry The purpose of this lab was to create an experiment to find the heat of fusion, the amount of joules(energy) needed to change water from solid to liquid and vice versa. My team found that heat lost is equal to heat gain. To find the heat of fusion we must first find the heat released by the water.…

    The "Control" icecube was melting faster than the "Testing" icecube in the first 10 minutes. After 10 minutes, the "Testing" icecube started melting at a faster rate than the "Control" icecube. This might have been because the "Testing" icecube drew enough heat particles from the alcohol for it to melt. Visually, the "Testing" icecube started melting from the middle which did not affect the height however, the "Control" icecube started melting from the bottom which was the reason why it seemed as if it were melting…

    From the data, we were able to conclude that calorimeters are used to determine the calories present in different foods. Additionally, after the pringle burned, the mass was reduced by 1.49g, while the temperature increased by 22°C as it took the heat that came from the burning of the pringle. From then, you can use datas from the data table to calculate the amount of calories burning per grams such as 1.48 Calories/gram for the first trial. Heat is the energy that is transferred between objects when there is difference in temperature. Objects obtain heat as a result of the small, rapid motion that all atoms experience such as vibrations, rotational motion, and electron spin.…

    We’ve been hearing about it for years, “The polar bears are going to go extinct because of global warming!” But is it really true, or is it just a clever marketing ploy utilized by environmental corporations? For decades the apparent phenomena of the planet warming has been a major global story. Vehicles are being made to be more “energy efficient”, companies are getting fined for harming the environment, and the majority of people recycle. But yet, the media presence of global warming advocates is stronger than ever, leading some to believe that maybe it’s all one big fairy tale.…

    In part C, the enthalpy of formation of magnesium oxide was found by adding together three reactions, as shown in the table below. Experiments were performed to obtain the ΔHrxn value of the first two reactions in the table, which were reactions 4 and 5 respectively in the experimental section, while the ΔHrxn for the third reaction in the table was provided. Using the ΔT obtained experimentally, heat energy (q) was determined using the equation q = mCΔT + CΔT where q was the heat, m was the mass of the solution, ΔT was the change in temperature, C was the specific heat of water, and C was the calorimeter constant. The mass was calculated by multiplying the density of the solution, which was 1.01 g/mL, by the volume of solution.…

    All things are made of atoms that have constant movement, like five year olds on red bull. So these molecules and atoms make energy in the form of heat from their energy, similar to what your body does when it works out and you start to get hot. Therefore all matter has at least some thermal energy, no matter how small or minute it is. There is different types of energy but this essay is meant to inform readers of conduction, convection and radiation because they all deal with thermal energy. As previously stated, matter has energy but the amount of thermal energy determines the physical state of the matter.…

    Cool water was placed into the calorimeter and its temperature recorded, while an equal weight of water was heated to 35.3 ⁰C. The heated water was immediately poured into the water in the calorimeter and the temperature was recorded. The water equivalent of the calorimeter could then be calculated. Approximately 100 g of cool distilled water was placed into the calorimeter and the initial temperature recorded. Solid sodium sulphate decahydrate crystals of 4.00 g were added to the water in the calorimeter and stirred until it dissolved.…
