Would Salt, Sugar, Or Sand Work Better?

Other substances that dissolve in water also lower the freezing point of the solution. The amount by which the freezing point is lowered depends only on the number of molecules dissolved, not on their chemical nature. This is an example of a colligative property. In this project, you'll investigate different substances to see how they affect the rate at which ice cubes melt. You'll test substances that dissolve in water (i.e., soluble substances), like salt and sugar, as well as substances that don't dissolve in water (i.e., insoluble substances), like sand and pepper. Which substances will speed up the melting of the ice?

*Topic Sentence – What key point to do want to make in this paragraph about both texts? Different text, vocabulary types and camera techniques. * Evidence 1: (Key quotation/scene/technique) The techniques of text and vocabulary that are directed by Russell Mulcahy, uses the Australian dialect, which is common English mixed up with Australian slang, “Coppers came out “-‘Harold Fingleton’, Swimming Upstream 2003, This quote illustrates the Australian slang word for Police or Policeman.

3. Do you think sugar or salt will melt at a higher temperature? Explain your answer.

The objective of this experiment is to test the melting point of ice against different variables. I will use a control of ice against air and test this next to ice in water, sugar on ice, salt on ice and Baking Soda on ice. By measuring the melting time of each element on an ice cube I will be able to tell which element affects ice’s melting properties at what rate.

A glacier is a large body of ice that moves slowly across land and are formed by there being a higher snow gain rather than a snow melt. Glaciers move by a small amount of ice melting and the glacier sliding. Glaciers can help and destroy the landscape in front of them but they can also shape the land into something amazing. Glaciers were once present in Minnesota thousands of years ago and played a massive role on the landscape we live on today, and as they melted they left behind large amounts of water and formations.

In other words, it takes less energy to raise the temperature of the salt water 1°C than pure water. And in the winter time, adding salt to the ice lowers its freezing point, so even more energy has to be absorbed from the environment in order for it to melt.

~ Glaciers are formed when snow builds up for several years from snowfall that exceeds snow melt. Over time, as new snow compresses the existing snow, the weight causes the snow underneath to turn to ice. The hardening effect is similar to what happens when you pack a snowball in your hand. The pressure from additional layers of snow builds for up to thousands of years. Glaciers can grow and shrink as a result of changes in the amount of snowfall

A glacier occurs when the climate of an area is so cold that new snow does not completely melt each summer and more snow is added in the winter. After many winters the accumulation of this snow becomes compact and re-crystallizes, thus forming a glacier. Currently, glaciers cover about ten percent of the Earth's surface. Yet, in the past, glaciers covered much more land and were thousands of meters thick. (Tierney)

The Effect of Sugar On The Melting Rate Of Ice. Abstract: The melting rate of each type of ice cube was different, depending on whether they had sugar in them or not. One type of ice cube contained sugar, where the other one didn’t, and as a result, the lowering of the freezing point of the water seemed to be affected by the sugar.

Something cool about keeping your ice cream to last longer from melting without a cooler will be to place it in a plastic container and put a thick towel around it. the towel will

The Roman Republic, known for its grounding principles and spread of power is the basis of politics in many western cultures and some of its implements are still used today. The power of the Roman people allowed them to govern during the Roman Republic but only centuries later in Imperial Rome did the power fall to only one man. The transition from the Roman Republic to Imperial Rome is known to have many different causes but the sum of them led to war, war then led to conquerors and conquerors seized all of Rome’s power. The Roman Republic highlights Rome’s initial plan for prosperity but corruption quickly leads to chaos. Amidst the chaos leaders become evident and with followers they grow to be supreme rulers.

Intermolecular forces hold molecules together when they are in solid or liquid state. However, water has the ability to dissociate many salts and ionic compounds. This is called dissolving. When NaCl is added to water, it dissociates into the ions; Na+ and Cl- . The positive sodium ions are surrounded by the slightly negatively charged part of water molecules (i.e. oxygen) in the water molecules and the negative chlorine ions are surrounded by the slightly positively charged part of water molecules (i.e. the hydrogen). The kinetic energy of the sodium chloride molecules increase with temperature. This destabilizes the solid state that it is currently in. This increased motion means that the molecules are less able to hold together and as such they dissolve at faster rates and larger amounts.

My loneliness was cold, shivering with no hope for warmth inside. I always watched other colonies huddle to work together as I sat on the side. Even if I begged them to join, I was constantly rejected. They jumped every time they saw me, shook in fear and believed I was going to harm them. Even the giants around me had family and friends.

Future manned expeditions could melt the ice into water, for drinking, washing and turning into rocket-fuel: there is enough ice to make a lake 10km across and 10m deep.

“ Shoot all the bluejays you want, if you cant hit ‘em, but remember it's a sin to kill a mockingbird. “ Racism persecutes innocent people for no good reason. In Harper Lee’s novel, To Kill a Mockingbird, there are various primary forms of prejudice in the novel. There is a trial of Tom Robinson on which the story centers. Aunt Alexandra creates a controversy in the Finche household about Calpurnia, their cook and surrogate mother figure. Lastly, Boo Radley, subject of discrimination because he is a mystery to the children and to the town. Harper Lee shows throughout the novel how the severe the towns people are towards discriminating against innocent people.
