The measuring cylinder was then used to accurately measure out 20 mL of water, which was then poured into the test tube that would be used for the experiment. The test tube was then placed into the clamp, which was then adjusted in order to make sure that the test tube was grasped firmly and would not fall out.

If the water displacement increases, then the density will decrease because the mass will be divided by a higher volume causing a lower density. The independent variable is the water displacement and the dependent

Purpose: Weighing objects. Figuring out the density with an object by calculated volume and Archimedes’ Principle.

Attraction between water molecules which allows insects and other objects to float a top the water

13. If a soil has a moisture tension of 0.15 bars and the salinity of the soil water is 1.86 dS/m, what is the total tension experienced by the plant roots? That is, what is the sum of the moisture tension and the osmotic (due to salinity) tension?

The turgor pressure must be equal to the water potential if there is no net diffusion. The cell and environment have reached equilibrium and the movement of water is equal on both sides.

Since this solid block is more dense than water (1.536 g/cm3 > 1 g/cm3) it will sink.

First, we will set up the force table. The table comes in three separate pieces the base, stand and table once we connect and fasten all three parts we must use a circular level to make sure the table is balanced. If the force table isn’t balanced then we must adjust the base’s feet to the appropriate levels on each leg till the bubble on the level is centered. We must then assign where the positive & negative x, y axis are on the force table as a point of reference and label them with tape .Then for part I we must apply 1.96 N in the positive x – direction, and 2.94 N in the positive y-direction then we must balance the two with a third force and record the magnitude and direction of it and a draw a diagram showing all three forces. Part II

4. Take a piece of dialysis(as cut earlier), find the mass of the dialysis, and the zero out the scale on

This is the final step of the experiment. The shell-less egg was now placed into a new cup, but very carefully, as the egg was more fragile than when it was soaked in vinegar. The egg in the new cup was then covered with water. The egg sat in the water for a 24 hour time period once again. During this 24 hour time period the eggs appearance and size were once again recorded. After the time period had completed, the egg was removed from the water and was very carefully patted dry. Since the egg was now swollen, extra care was needed when holding the egg. The swollen egg was placed on the scale on last time and its mass was recorded as M3.

The water rocket flies really high in to the air. There wasn’t too much unexpected observations happening. Our hypothesis is more of the water higher the rocket flies, and greater the pressure, higher the rocket goes. Based on our data, our hypothesis is not correct. The rocket flies highest when the water is about 250 ml and the attitude is about 124. However for the second one our hypothesis is correct. Our experiment clearly relates to Newton’s Law of Motion. When the pressure pushes out the water, there is a action upon the ground and there is also a opposite and equal reaction that makes the rocket flies. So that more pressure will create more reaction. Also if the water

Can water float on water? This research paper is going to talk about water in density. Terms that will be discussed in this paper will include salinity, density, hydrometer, and thermohaline circulation.

This experiment is designed to facilitate an understanding of the principles involved when water flows through a pervious material such as soil.

The specific purpose of this experiment was to verify three physical concepts based on Newton’s Laws. These concepts are vector addition, force as a vector, and the law of equilibrium. The densities of two different objects were compared by measuring their masses and volumes. In this experiment, two different sets of methods of volume measurement were compared to the density computation of an object bearing a standard shape. In addition, the density computation was used to determine the buoyant force acting on different objects. At this point, it was observed that an object maintains a constant velocity if all the external forces cancel out one another (no net force results from the unbalanced forces acting on an object). In this case, a force table was used to study Newton’s First Law of Motion. These forces were represented as F1, F2, and F3. Analysis of results obtained from the experiment proved that the value of F3 determined through calculations was less than the measured value of F3. In Trial#1, for example, the calculated value of F3 was 211.59g @ 2430 while the measured value of F3 was 215g @2430, translating to a % difference of 0.5g @20. Although the primary objectives of the lab were achieved, errors (in particular, static friction) occurred during the experiment. These errors were observed
