Abstract: This report presents the reason why the ocean does not freeze in the winter. Since the ocean consists of salt water‚ an experiment was done to test the effect of freezing on salt water compared to pure water. The experiment was conducted three times in order to obtain accurate results and eliminate errors. In addition to the salt and pure water experiment‚ a variation of this experiment was created to test other options. In the variation experiment the effect of freezing on sugar water

The masses of weight boat and mixture were determined by using electronic balance. Poured the mixture into the sieve. Held the sieve over a weight boat. The sand and salt past through the holes into the weight boat. The gravel remained behind in the sieve. Shook the sieve back and forth made sure all the sand and salt particles past through the sieve into the weight boat. The masses of gravel with weight boat and left mixture were determined by using electronic balance Separated

Discussion: 1. Peter was preparing some potatoes for cooking. He put some water in a pot and added some salt. He cut up the potatoes and put them in the salt solution. Then the telephone rang and he spent 30 minutes talking to George. When he returned to put the potatoes on the stove they were flaccid (soft). Explain what happened to the potatoes. The concentration of free-moving water molecules is higher in potato cells‚ the cytoplasm of the cell is hypertonic. The water molecule will flow from

Many years ago‚ when I was a kid I went to Mexico regularly to surf the coast off Baja California. There was plenty of fish to catch and there is a way of cooking a dish called‚ “Ceviche” (.ehow.com… make-ceviche.html) unfortunately one time when we were many miles south of the boarder and no store in just as many miles we had no salt. We built a fire‚ collected

Introduction For the past 30 years Scientist have searched desperately for the answer to salt toleration within plants. The damaging effects of salt accumulation in agricultural soils have influenced both ancient and modern day civilizations alike. Worldwide‚ an estimated 24.7 million acres of once agriculturally productive land are being lost annually due to irrigation-induced salinity‚ according to the U.S. Department of Agriculture. Thus‚ crop production is limited by salinity on 40% of

water molecules as part of their crystalline structure. Water is bound in most hydrates in definite‚ stoichiometric proportions‚ and the number of water molecules bound per metal ion is often characteristic of a particular metal ion. Many hydrated salts can be transformed to the anhydrous (without water) compound by application of heat. In this experiment‚ we determine the empirical formula of copper (II) sulfate – CuSO4. II. EXPERIMENTAL In this experiment‚ we used an electronic balance to

During the Toxicity of Morton Salt on Radish Seeds experiment‚ we measured the levels of iodized Morton Salt to the growth rate of radish seeds. Each six packets had ten radish seeds with different level of iodized salt solution. The packet with no iodized salt solution grew the longest in a period of days‚ compared to the other packets that had iodized salt. Solutions 100% and 10% had no growth progress within the past five days. As for solutions 1%‚ .1%‚ and .01% grew‚ yet not as much nor fast
