Bernoulli’s theorem is a special application of the laws of motion and energy. The principle equation describes the pressure measured at any point in a fluid, which can be a gas or a liquid, to the density and the velocity of the specified flow. The theorem can be explained by the means of imagining a particle in a cylindrical pipe. If the pressure on both sides of the particle in the pipe is equal, the particle will be stationary and in equilibrium. By implementing the second law of motion the

Law of Conservation of Mass Experiment CER Question: Does a controlled (closed system) zip lock bag experiment demonstrate the Law of Conservation of Mass? Claim In our class we did an experiment where we put different known supstances into a ziplock bag and closed the bag, that way we could achieve a closed experiment and attemp to support The Law of Conservation of Mass. The Law of Conservation of Mass states that mass can neither be created nor destroyed in a closed system. According to my data

Figure 1 shows the visual output of transforming the quantitative information presented in Table 1 into the so-called bubble plot, which is essentially a special version of a scatterplot (Kabacoff 2011, p.278f.). The graph in Figure 1 visualises co-occurring nominal collocates of hot and warm in the COHA decade of the 1860s. The x-axis designates the co-occurrence frequency per million words of collocates with hot whereas the y-axis portrays their co-occurrence frequency per million words with warm

Density: A Characteristic Property I Purpose The purpose of this experiment is the density of six different substances. The way to figure this out is by finding the mass and volume of each of the substances. The hypothesis for the different experiments is that with each of the different substances and mixtures will be different depending on what they are. II Equipment The late nite lab was used to conduct this experiment. The product used were a balance, a graduated cylinder, water, Ethanol, and

50. atomic radius, trends in the periodic table As you go across the periodic table, the atomic radius decreases because the number of protons increases along with the number of electrons but the shielding does not change so they are more attracted to each other and the electrons are pulled more inward which makes the atomic radius smaller as you move across the periodic table. 51. Rutherford’s experiments, gold foil, alpha particles This requires a basic understanding of Rutherford’s experiment

Patterson’s Class) This is because momentum is defined as mass times velocity (mv) (physicsclassroom.com). Anytime 2 or more objects collide they exert equal but opposite forces on each other as defined in Newton’s third law of physics (physicsclassroom.com). Newton’s second law of physics is defined as F=ma where force is any interaction with another object, or mass multiplied by acceleration (physicsclassroom.com). So this force between the 2 or more objects cannot ever add or take away momentum from them

The purpose of this lab is to use the combined gas law to find the new volume of the can after the temperature has changed. Also in this lab, the volume changes again and it is found using water displacement. The dependent variable in this lab would be the volume. The independent variable in this lab would be the temperature. Under the microscope, solids can be seen as particles in a highly ordered or fixed position. Liquids can be seen as particles that can move loosely and start to show some

This reflective writing will discover and highlight the major patient care concept in relation to my personal experience and feelings. Throughout this essay, my reflection will be based on how well I was able to treat the patient who was suffering from severe pain in surgical ward. I will further explore the pain assessment as conducted with one 70 year old patient whom I will refer as Mr X. while describing my overall experience with a single patient, I will also reveal and share some questions

At the macroscopic level when a firework goes off the effects of molecules interacting can be observed through the light being produced. I expect the firework to travel to a high distance vertically in the air. I expect the firework to start in a tight ball. As it travels the tight ball (of molecules) will expand in its perimeter causing the firework to combust, making a very loud bang. I’m sure that heat radiates as a outcome of this interaction, though it wouldn’t be smart to get close enough to

between the positive and negative charges. Periodic tables are given in textbook, however, mosts data isn't given because they can be too “complex” which does not help us students understand what science really is. However, if we go deeper into the concept of ionization energy, we can learn more on electron shells and valence electrons by showing tables of successive energy. Based on the tables we saw, removing a the second electron from an atom requires a lot more energy than removing the first electron

My question looks at how gravity, and the weight and size of different balls affects how long it takes to hit the ground. The balls I choose was the American football, golf ball, baseball, and tennis ball. As learned in this experiment, weight and size affect how fast the ball drop because gravity will cause the heavy ball to drop faster. This means that the heavier ball should fall faster, while the lighter ball should fall slower. I choose this topic because I want to know if ball sizes influence

DENSITY is a physical property of matter, as each element and compound has a unique density connected with it. Density defined in a qualitative manner as the measure of the relative "heaviness" of objects with a constant volume. For gases the density may amount with the number of gas molecules in a constant volume. Helium balloon: Compare the behavior of helium filled balloon with that of an air filled balloon. Even taking into account the weight of the rubber balloon, the helium balloon floats

The volume, temperature and pressure exerted by a particular gas are highly dependent on one another. This is explained by several Gas Laws. Boyle’s Law states that when the temperature is kept constant, pressure of gas is inversely proportional to the volume. Relating this principle to molar volume, the higher the pressure, the smaller the volume the gas particles occupies. When the volume of the container enclosing the gas is reduced, there are more gas particles per unit volume. The gas particles

Chapter -1: OBJECTIVE the more general When designing a small temperature control system, the best choice for a refrigerator/heater element is often a thermoelectric cooler (TEC). The operation of these devices is based on the Peltier effect, which was discovered in 1834 by Jean Peltier. When an electrical current is passed through the junction of two dissimilar metals (Figure 1), heat is also transferred across the junction. To pump heat, a thermoelectric cooler can require a significant amount

The electrons in an atom occupy different energy levels. When all of the electrons are at the lowest possible energy level they are said to be in the ground state. Sometimes they can be promoted to a higher-energy electron shell. First, the electron can absorb a photon of just the right amount of energy to move it from one quantum shell to another. Second, when atoms are heated their electrons can gain energy from the heat. When an electron is in a higher-energy shell it is said to be in an

There are three ways of creating charges, friction, conduction, and induction. An electron is a negative charged particle, a proton is a positively charged particle, and a neutron is a particle that has no charge A nuclear force, between a proton and neutron stick together to form a nucleus. The neutron inside of the nucleus has no charge, so it’s considered positive because it combines together with the protons, which is positively charged. The negative charged electron orbit around the nucleus

I want you to picture these two scenarios Imagine yourself stuck in a forest in Madagascar and while walking around searching for.. lets say.. food. All of the sudden, you hear some irritating noise coming from behind … and then you find this “weird looking hairy and scary creature” Incase you don’t know what this is. This is the Aye-Aye. It can grow up to 15 inches in height. These ugly creatures are known for their long, bony, witch-like middle finger. (Whispers) Rumors say that if an aye-aye

All the fundamental vibrations are IR active stable structure. The harmonic vibrational frequencies calculated for doped fullerene with glycine have been compared from low frequency (below 1000 cm-1) to high vibrational frequency (above 1000cm-1) as shown in Table5
