It is very important that a person stays hydrated because water makes up more than half of your body weight, and not staying hydrated can result in your body shutting down and possible death. Your body uses water in many ways, all the cells in your body need water to function. All of your body’s tissues need water, and all of your body’s organs need water to function correctly. Some of the ways that your body uses water are ; water is used to regulate your body’s temperature, you sweet to lower your temperature when your body is overheating. Water is also used to carry vitamins and minerals to our body’s cells.
Part 1: Scemario 4 Carmen conducted an experiment to determine whether salt added to a cup of water affects its freezing point (the temperature at which it freezes). After some research, she hypothesized that the greater the amount of salt dissolved in the water, the lower the temperature at which the water freezes. Water samples were prepared containing equal quantities of water at the same starting temperature. Each sample received a different amount of salt and was placed into a freezer. The length of time it took for each sample to freeze was recorded as shown below.
• Water flushes toxins out of vital organs, carries nutrients to cells and provides a moist environment for ear, nose and throat tissues. • Every day you lose water through your breath, perspiration, and elimination of waste products. • Even mild dehydration can drain your energy and make you tired. • For proper body function, you must replenish its water supply by consuming beverages and foods that contain water. 3 Water: How Much Should You Drink on a Daily Basis?
The highest temperature ever recorded in the United States was 134 degrees F at Greenland Ranch in Death Valley, California. 19. In 1899, it was so cold that the Mississippi River froze over its entire length. 20. The United States uses an estimated 10 million tons of salt each year to melt ice on the roads.
Too much salt can cause your body to create kidney stones or a hard mass formed by clumps of calcium and sodium. Many of these kidney stones have sharp edges causing it to become very painful to pass one through the urinary system. The shape edges of the stones can not only cause tears along the inside of the ureters, but due to the blockage of the urinary system it could cause kidney disease such as Crohns disease. Some of the types of kidney stones are calcium oxilate stones and uric acid stones. Lowering the limit of sodium or salt consumption can only benefit us.
If you do not seek immediate help you may be at risk for heat injury, swelling of the brain, seizures, low blood volume, kidney failure, coma or even death. Symptoms for mild to moderate dehydration (In which you should increase fluids to reverse) * Dry/sticky mouth * Fatigue * Thirst * Decreased urine output * Dry skin * Not able to produce tears while crying * Headache * Constipation * Dizziness Symptoms for severe dehydration (In which you should seek medical attention) * Extreme thirst * Lack of sweating * Sunken eyes * Little or no urination * Very dry mouth, skin and mucous membranes * Low blood pressure * Rapid heartbeat * Rapid breathing * Fever * Delirium or unconsciousness Treatment * Drinking water * Using an
Cold blooded animals don't do this (which is why they eat less and live longer), so their temperature could fluctuate with environmental changes. This would be bad for them (think of the optimum temperatures for enzymes etc.) so they need to regulate this. Water's high specific heat capacity means that it needs a lot of energy to warm up, or it needs to lose a lot of energy to cool down. Animals that have a lot of water in them need larger environmental temperature changes to effect their body temperature.
Part E – Deriving a solubility curve Aim: To be able to calculate the solubility of the compound in a certain amount of water as the temperature increases or decreases. Hypothesis: As the water increases, the solubility decreases and the substance’ saturation would get lower. And as the volume increases, the substance won’t separate to the water anymore which makes it dissolved forever without getting crystallized when the water cools down. Apparatus & Method: [refer to the sheet p. 64] Result: Temperature | Volume [ml] | Solubility [g/100g] | 65 ̊ C | 5 ml | 130.44 g | 46 ̊ C | 8 ml | 81.525 g | 39 ̊ C | 11 ml | 59.29 g | 28 ̊ C | 14 ml | 46.586 g | 22 ̊ C | 17 ml | 38.36 g | 16 ̊ C | 20 ml | 32.61 g | 12 ̊ C | 23 ml | 28.35 g | 12 ̊ C | 26 ml | 25.08 g | The solubility was calculated with the formula of: Solubility=6.522gml of waterx 100 The solubility of Potassium Nitrate is directly affected by the temperature of the solution. As the temperature of the solution rises, the solubility of Potassium Nitrate increases.
Drinking water from the tap tastes different, and its not a very safe thing to do I believe. The chemicals that are used to filter the tap water, such as, chlorine, lead and giardia, are toxic and it’s very dangerous for humans. The process of filtering the water strips out all the natural minerals that are found in the water, and our body needs it. While the bottled water is all natural resources, which means the natural minerals are still there. Also it feels like drinking water that its fresh and tasty.
