Blank 1 Blankity Blank Blankity Blank Mr. Blank 4/9/02 Effects of Salts on the Freezing Point of Water In this experiment‚ you will study the effect that several solutes have on the Freezing Point of water. When a solute is dissolved in a liquid‚ the temperature at which that liquid freezes decreases‚ because the molecules of the solute become attached to the water molecules‚ making it more difficult for the water to form its crystaline shape and form into ice. This process is called Freezing

My conclusion is that the higher salt concentration in the solution the greater the decrease in mass of the potato will be‚ the graph I have drawn supports my conclusion. The 10% salt concentration shows that on average the potato loses 2.6% of its overall mass. 20% salt concentration shows a further decrease in mass this time it is an average of 13% overall mass decrease. 30% salt concentration shows an average decrease of 18.8% in overall mass. The 0% salt concentration actually shows a mass increase

if an egg will float in salt water. The question is how much salt is needed to be added to the water to make the egg float. The problem is that no one knows how much salt is needed to make an egg float. Hypothesis It will take at least three teaspoons of salt to be added to the water for the egg to float. The reason why I think three teaspoons of salt will need to be added to water for the egg to float is because the egg a density that is lower than the density of the salt water.

Can salt change water’s density? I conducted an experiment using common household items to find an answer to my question. The procedure involves filling two cups with two hundred fifty milliliters of water. Then‚ mixing teaspoons of salt in water one at a time‚ until you’re able to submerge a raw egg in the solution and have it float up. My hypothesis is‚ salt does infact change water’s density‚ and if the egg floats it’s proof of density change in the water‚ because it must be less dense than the

The killer second hand clothes shop. The record store. All the places that held his memories‚ memories of the happiest time of his life. He hadn’t been that happy since. And as he walked into the beautiful steampunk-esque Barnes and Noble in Harbor Place‚ Castiel Novak couldn’t help but feel like he’d come full circle.
