Regular Ice Cubes

Some of the first things that come to mind when people think of energy are high level experiments that are conducted in labs. However, energy is just what is transferred from one object to the next when a reaction takes place. Energy is constantly being used in everybody’s daily life. Whether they know or not, everyone is constantly using some form of energy. Everything from walking, eating, and sleeping are all utilizing energy in different ways. Even applying ice to keep a glass of water cold is exerting a form of energy (“Heat Transfer”). Just like everything else, even ice releases a form of energy when put in water. This type of energy is a mix of convection and conduction. Convection is when thermal energy is transferred from one hot …show more content…
An experiment of testing whether regular ice cubes or plastic ice cubes keep a glass of water cooler for longer will prove how energy works in daily life. For the investigation, two glasses of water will each have a different type of ice placed in them. One will have regular ice cubes while the other has plastic ice cubes. Both will use convention and conduction energy, but it won’t know until after the experiment which form of ice keep the water cooler longer. The independent variable in this experiment would be the type of ice cube being used. In this case, the type of ice cubes being used are regular and plastic ones. The dependent variable will be the temperature of the ice cubes. Finally, the controlled variable will be the amount for water poured in the glass and the amounts of ice cubes used for each glass. The expected outcome of the experiment is that the regular ice cubes will keep the water cooler longer. This is because due to convection and conduction energy the ice will melt and mix with the water. On the other hand, the plastic ice cubes will also melt, but since the previously frozen water is contained inside the plastic it will not mix with the original water inside the glass. Therefore, causing the water to be kept cool for a shorter period of time. Lastly, it is time to test the …show more content…
Both glasses of water were 50 °F. Next, I gathered eight regular ice cubes that were 25 °F and eight plastic ice cubes that were 25 °F. Both glasses of water ice were left in a room that was 68 °F. For the next hour I used a thermometer to check the temperature of both glasses every two minutes. After the ten minute mark, I waited and only checked the temperature of the glasses every fifteen minutes. I continued to do this for four hours and thirty minutes and then concluded the experiment even though not all of the ice had completely melt. As shown on my data table (located on page four) both types of ice cubes kept the water a steady and cool temperature for a long time. They also both were extremely similar in temperature for most of the experiment. However, it did show that the regular ice kept the water slightly cooler than the plastic ice did. As mentioned before, the reason behind the ice melting and keeping the water at a low temperature was caused by convection and conduction energy. The whole investigation showed how these two forms of energy are used in everyday life like putting ice in a drink to keep it

    (Goff) Creams and milks with high fat contents are suggested for the most uniform texture and rich taste. The lipids in this experiment won’t get hot enough to degrade or have a significant affect, but the different concentrations of milk fats should alter the composition of the ice cream. Hypothesis If ice cream mixtures with different fat contents are cooled in an ice cream maker for the same period of time, then the mixture with the lowest fat content will reach the lowest temperature and be the thickest.

    The solid and gas are small particles in the form of ice crystals, fat droplets and air bubbles in a continuous phase in the matrix. The following decribes the functions of different components of ice cream: Ice crystals: Ice crystals give solidity to the ice cream body. Ice crystals are formed when the water at the base starts to freeze. The size of the ice crystals determines how fine or grainy the ice cream is. So the main objective to be considered while forming ice cream is to keep the size of the ice crystals as small as possible.…

    Does the type of liquid affect how fast an ice cube melts? Does the type of liquid affect how fast an ice cube melts? In an experiment (not ours) involving three liquids, pop melted the ice within it the fastest out of the three. Molecules cause ice to melt in a pretty simple way. When salt is thrown on snow or ice, it prevents the ice or snow from freezing over once again.…

    Melting Ice Essay

    Since table salt is refined and has added chemicals to it, the ice is predicted to melt at a slower rate, while the ice is predicted to melt at a faster rate when rock salt is added to it. This is due to the thicker composition that rock salt has, which is on the contrary of the finer composition that table salt and sea salt have. Both table salt and sea salt are made up of smaller particles than rock salt, which therefore will affect the ice differently. The different added chemicals in table salt will affect the melting of the ice differently than the sea salt, which has no added chemicals. Although sea salt contains no additives, it is still not predicted to melt the ice at a faster rate than rock salt.…

    Looking at hockey players and figure skaters, we can start to get a clearer answer. One notion called pressure melting, creates a thin layer of liquid water. This is explained as a skater’s weight exerting a great deal of pressure per square inch of ice that causes ice to drop its melting point. Furthermore, ice is less dense than water, this lower density of the ice means that the melting point of ice can be lowered below the normal zero degrees Celsius by squeezing it. Increasing the pressure also reduces the volume available; Le Chatelier’s Principle, states if a system in equilibrium is disturbed by temperature, pressure, and concentration of components, the system will shift its equilibrium position to balance the effect of the disturbance (Norwich).…

    Texture and drip loss are similar, as more damage to the tissues yields a higher drip loss and a mushier texture, so there should be similarities between the two graphs. However, since blanching softens tissues, a more negative score on the texture scale should be seen with more blanching time. This is seen in the graph. There is a downward trend between blanching time and texture, where the longer the beans were blanched, the mushier they became. There was not a huge difference seen in texture between the freezing methods, but it should be noted the control group, which was frozen in the pilot plant freezer retained its texture the most, which was not expected because it should have had more tissue damage, resulting in a mushier texture.…

    When this happens the water molecules web together and the water becomes ice. The reason the salt and sugar lowers the freezing point and the water takes longer to freeze is because the salt or sugar molecules interfere with the attraction between the water molecules and therefore interfere with the webbing of the water molecules which prevents the water from turning into ice, when the water temperature lowers even further it eventually reaches a temperature where the water molecules slow down so much that the molecules are able to become a solid even with the presence of salt or sugar. What will freeze faster water, sugar water or salt water? The plain water will freeze the fastest because there is nothing interfering the freezing process. The sugar water will freeze next and the salt water will be the last to freeze.…
