The 5th state of matter INTRODUCTION Ice is transformed to water at 0°C when the energy of its molecules (particles) increases. Water is similarly transformed to vapor at 100°C (Fig.1). Much stronger zigzag motion of the particles separates and ionizes hydrogen and oxygen i.e. plasma comes into existence (above 13 000 K). Do all bodies fit one of these four states of matter? The answer is: no‚ e.g. the solar corona does not! Fig. 1 The temperature scale. It starts at 0K. Is it infinite long

speakers being implanted into the power mat so you can listen to music and be able to charge your device using one device. BREAKTHROUGHS In order to be able to make our new technology possible‚ we would have to find a way to make a stronger electric current and be able to make it turn into a larger magnetic field so it can charge the devices from a distance.

Between the desktop top computers and laptops to the smart phone everything can be stored using less space and the ability to locate stuff so much more easier that if the world of today lost computers around the world for even

electrical current‚ which is measured in a unit called amperes (also called amps for short). Electrical current cannot just flow on its own; it needs something to "push" it. Voltage (also referred to as electric potential) is what pushes electrical current through wires. Voltage is measured in volts‚ and the symbol for volts is V. The general purpose is to determine the voltage of a potato; with this experiment we intend to answer the following questions: 1. How much voltage and/or current does it

Erickson & Kevin Haar February 14‚ 2014 PreLab With the new understanding of quantum mechanics and solid-state physics in the 1930’s came the development of semiconductors. Semiconductors are materials such as silicon and germanium in which the current density is non-zero‚ unlike an insulator‚ yet still several magnitudes smaller than that of a conductor. There exists a significant energy gap between the filled valence – highest range of electron energies normally present at absolute zero – and

electrons move through a conductor‚ electricity flows‚ which illustrates the moving of electrons in the wire which collide with the ions in the metal. This then makes it more difficult for the current to flow‚ causing more resistance. When these electrons move they create an electric current. The electric current being measured from different lengths of wires is what this experiment is conducted by. Hypothesis: The hypothesis for this experiment is this: as the length of the conductive putty wire

Battery Purpose To demonstrate how an electrical current can be generated using citrus fruits (such as lemons or limes) that is strong enough to power a small light bulb. Additional information Batteries are devices that store chemical energy and convert it to electrical energy. Consisting of one or more voltaic cells‚ batteries come in various sizes and forms and are integrated into most electronic and portable devices. Electrical current is the flow of electrons (movement) of an electrical

This increases the amount of collisions therefore there is more resistance. However it is hard to keep the temperature exactly the same as the room temperature might change from day to day. It is essential to use a low voltage because it means a low current that will not heat

DC Circuits: Electric Power PHY 114 Lab Report 10/09/2013 Abstract: The purpose of this experiment was to look at electric power dissipated in a load resistor in a circuit with a real power source‚ which has a finite internal resistance. We discover a surprising result about how to deliver the most power to a device from a source. Consider a simple circuit in which a battery of voltage drives a current through a resistor of resistance. As we have seen‚ the battery is continuously doing
