• ## Bernoulli's Theorem Essay

734 Words  | 3 Pages

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

• ## Explain The Volume, Temperature And Pressure Exerted By Several Gas Laws

952 Words  | 4 Pages

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

• ## Thermoelectric Cooler Lab Report

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

• ## Density Of Balloon Essay

762 Words  | 4 Pages

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

• ## Molar Mass Of Gas Essay

829 Words  | 4 Pages

A volatile liquid can be easily converted to its gaseous state, the gas that forms from vaporization is known as vapor and it is assumed to behave as an ideal gas. One of the properties that characterize a volatile liquid is determination of its molar mass. Dumas method also known as the vapor density method uses the vapor density of the unknown volatile liquid in determining its molar mass. The major assumptions of these methods are the substance behaves ideally. The molar mass of a volatile liquid

• ## Essay On Heat Pump

1817 Words  | 8 Pages

3.1 Heat Pump A heat pump as shown in Figure 3.1 is a device that provides heat energy from a source of heat to a destination called a "heat sink". Heat pumps are designed to move thermal energy opposite to the direction of spontaneous heat flow by absorbing heat from a cold space and releasing it to a warmer one. A heat pump uses some amount of external power to accomplish the work of transferring energy from the heat source to the heat sink. While air conditioners and freezers are familiar examples

• ## Millikan Oil Drop Experiment

Determining Smallest Possible Charge on Droplet Using Millikan Oil Drop Experiment Simulation Abstract: The purpose of this lab was to determine the value of the smallest charge using a Millikan oil drop simulation on the TI-83+ graphing calculator. This was done by using a program on the TI-83+ graphing calculator, where an oil droplet was placed on the screen and cursor keys were used to adjust the voltage until the droplet is suspended. The droplets radius, voltage, plate separation

• ## Dalton's Law And Archimedes Principle Lab Report

1608 Words  | 7 Pages

Charles Reverand Mrs. Rick Chemistry H 12 March 2018 Determining the Molar Mass of a Gas with Dalton’s Law and Archimedes’ Principle Introduction Archimedes’ principle describes the idea of buoyancy. The principle states that an upward force acts on an object when submerged in a gas or liquid.[1] When the object is at rest, this force, called the buoyant force, is equal and opposite to the force acting downwards on the object.[1] The buoyant force is caused by the pressure of the gas or liquid the

• ## A Summary Of Respiration According To Boyle's Law

984 Words  | 4 Pages

The process of respiration occurs according to Boyle’s law. Boyle’s law states that for a fixed mass of gas at a constant temperature, the volume is inversely proportional to pressure. This means that as volume increases pressure decreases and vice versa. During inhalation the intercostal muscles and diaphragm contract resulting in an increase in the volume of the lungs and hence the thoracic cavity. As the volume increases, pressure decreases creating an area of sub atmospheric pressure within

• ## Helmholtz Coils Lab Report

1048 Words  | 5 Pages

Introduction When a charged particle is moving through a magnetic field, it experiences a magnetic Lorentz force given by F ⃗=qv ⃗ ×B ⃗ (1) where q is the charge of the particle, v is the velocity of the charge q and B is the magnetic field. In this

• ## The Mathematical Relationship Between Pressure And Volume

789 Words  | 4 Pages

The mathematical relationship that exists between pressure and volume when temperature and quantity are held constant is that pressure is inversely proportional to volume. This relationship is known as Boyle’s Law. P1 x V1 = P2 x V2. When the volume of a container is decreased, when still containing the same amount of molecules, more molecules will hit the sides of the container, thus increasing the pressure. We were asked to graph pressure and the inverse of volume because the graph of pressure

• ## Water Rocket Lab Report

958 Words  | 4 Pages

the launch pressure is at launch, the higher the thrust and therefore, the higher the rocket will reach; this also works in the other way. However, having very high pressure is not necessarily a good thing, it can be potentially dangerous. National physics laboratory from the UK recommends the maximum launch pressure to be no higher than 5 bars, which is approximately 5 atm. Having too much pressure can lead to the rocket exploding or other disastrous consequences, this will be further discussed about

• ## Essay On Ocean Currents

1935 Words  | 8 Pages

Ocean currents and wind currents are a huge part of the systems on earth. They have global impact on our environment and on mankind. There are many currents which all have their own characteristics and effects on different parts of the world. One of the world’s major ocean currents is the Kuroshio Current, a north-eastward flowing current, which flows along Japan and eventually merges with the easterly drift of the north pacific. The current transports warm, tropical water towards the polar region

Newton has discovered and proven many great concepts throughout his lifetime that he needs more credit for. His research about the three laws of motion was “still recited by physics students”(livescience.com). “During his lifetime Newton developed the theory of gravity, the laws of motion (which became the basis for physics), a new type of mathematics called calculus, and made breakthroughs in the area of optics such as the reflecting

It was called ‘A Briefer History in Time’. This book contained a summary and simplified concepts from his first two books that he had written, but he added in some new developments and ideas, such as string

• ## Materialism Vs Naturalism

He will counter that the laws of physics are not actually real; that they are just names given to regularities of the world discovered and documented by conscious beings (nominalism); or that they are mere concepts in the (material) mind—like the Pythagorean Theorem or the cardinal numbers—concepts that facilitate our talking about the world (conceptualism).[20] One understands the materialist’s argument, of course
