(2011, p.216-216) ADH regulates levels of urine output. High level of AFH increase water reabsorption and urine concentration, whereas lower levels of ADH decrease water absorption and dilute urine. ADH basically works in four stages. If our body has a low volume of blood and increased serum osmolality are sensed by the hypothalamus which signals the pituitary gland. Then the pituitary gland secrets ADH into bloodstream. After that ADH causes the kidney to retain water and water retention boosts…
Introduction: Density is how tightly packed matter is within a substance. Density is not to be confused with volume or mass. Volume is how much space an object occupies whereas mass is the quantity of matter that is within an element. In order to calculate density, the mass of the substance is divided by the volume of the substance. Density is the same for every substance. For example, all aluminum samples have the same density regardless of their mass. Each element on the periodic table has an…
Density Open Response Density Density is the mass per unit of volume of a substance. Density is measured in grams per milliliter (g/mL), or grams per centimeters cubed (g/cm3). The density of an object is what causes it to sink or float. If an object has higher density than the liquid it is being placed into, it will sink. If an object has a lesser density than the liquid it is being placed into it will float. For example, the density of…
water to binder ratio of M-S-H binder In development of M-S-H binder with magnesium oxide and silica fume, it is noted that silica fume has rather low specific gravity (S.G) and bulk density compared to Portland cement (PC). Thus, use of high silica fume content in the binder consequently results in a binder system of low specific gravity and bulk density, compared to PC. The light weight binder leads to a difference in water to binder ratio (by mass), compared to PC. To compare water content by…
When the egg was placed into syrup, a hypertonic solution, it shrunk in size. This result supports my hypothesis. The mass of the egg before it was placed in syrup and after it was placed in syrup changed drastically. There was a 16 g decrease in mass that happened to the egg during its time in the syrup. Both the long and short circumference of the egg decreased. The long circumference before the egg was placed in syrup was 18.75 cm and after it was taken out of the syrup the long circumference…
of the eggs is greater than the density of water. Then salt water 1-2 a spoon and stir in the eggs slowly, still also sank because of the eggs is still greater than the density of water. Drift An object that is dipped into the liquid will float if heavy objects are similar in style to the top or the object in equilibrium By the time the water was given a 2 ½ spoon of salt and stir gradually then egg will be on a State of drift. This happens because the density of water is equal to the mass…
Lab 4 in Chem 115 has three parts all calculating density. In part one, a 100 mL beaker, a volumetric pipet, and an analytical scale were obtained. To begin, the mass of the beaker was taken using an analytical scale. Then, 10.0 mL of an unknown liquid was transfered to the beaker using the volumetric pipet. Next, the mass of the beaker and liqiud was recorded along with the letter identifying the unknown liquid. By subtracting the mass of the 100 mL beaker from the mass of the beaker and liquid…
while the pretzel and control group continued to drop. I think this trend is explainable because those who drank liquid voided more liquid. In the second graph there is no distinct trend. In all but the control group the flow rate started relatively low and increased over time, the control group started incredibly high (36.52 mL/min) and dropped rapidly. The third graph looks at total dissolved solids in the urine. In all but the water group the TDS dropped slightly and then rose again, but in…
this experiment of both the solid-liquid extraction (on the left side of the table) and the liquid-liquid extraction method (on the right side of the table). It shows that in the solid-liquid extraction, most of the percentage recoveries were pretty low, all somewhere around 20 %. The only high percentage recovery was that of the neutral compound. This probably happened because the remaining solid that wasn’t dissolved with the acid, phenol, and amine like it should…
AIM OF THE PRACTICAL The aim of this practical was to investigate the reality or the accuracy of the formula for the resultant force on and the position of the centre of pressure on a vertical rectangular surface. SKETCH OF APPARATUS Counterbalance weight Balance pan(with 20g mass piece) Flat/curved surface(as shown below) Water Beaker Mass pieces(20g each) SUMMARY OF THEORY Hydrostatic force is the force exerted by the…
