States of matter are the distinct forms that different phases of matter take on. Historically‚ the distinction is made based on qualitative differences in bulk properties. Solid is the state in which matter maintains a fixed volume and shape; liquid is the state in which matter maintains a fixed volume but adapts to the shape of its container; and gas is the state in which matter expands to occupy whatever volume is available. This diagram shows the nomenclature for the different phase transitions

Measures of Astronomical Distances • Let’s view the Universe in terms of kilometres – The size of the observable universe is roughly 130‚000‚000‚000‚000‚000‚000‚000 km ! - Obviously measuring astronomical distances in km is inconvenient. - We need much BIGGER units of distance: • Some commonly used distance units: 1 ly (light year) = Distance traveled by light in 1 year = 9.46 trillion km 1 AU (astronomical unit) = average distance between the Sun & Earth = 150 million km A unit of distance‚

perturbation by an unknown planet. The planet named after the famous Greek god of the sea is Neptune. Neptune is the eighth planet from the sun. It is dark‚ cold and whipped by supersonic winds. Neptune is a gas giant; it is made of the hydrogen and helium. The planet takes about 165 Earth years to orbit the sun. A day on Neptune is 16 hours and 6.7 minutes. Neptune orbits the sun at a distance of 30.1 AU. In 2011 it will complete its first orbit since its discovery in 1846. Neptune is the fourth-largest

As impressive as technology is‚ it does have many negative effects on kids. Technology is not a substitute for good parenting. While Technology is here to stay‚ and it is progressing quicker than fathomable. While technology does have copious amounts of positives‚ it is having some rather ominous negative effects on kids. Kids are growing up too fast and are being exposed to too much at a young age. This will skew their view of the world and its inhabitants. It is rather difficult

He defined Fluorine as reacting violently with every element except Oxygen‚ Helium‚ Neon‚ and Krypton. Despite being stabilized‚ it was still deemed hazardous for it’s yet present destructive ability towards non-resistant objects‚ where an example of this nature towards inorganic material is that it may dissolve glass in its gas

Prashant Zanwar University of Central Florida I. Introduction To Maglev Technology And Application 1.1 Principle of Maglev System Maglev is a system in which the vehicle runs levitated from the guideway (corresponding to the rail tracks of conventional railways) by using electromagnetic forces between superconducting magnets on board the vehicle and coils on the ground. The following is a general explanation of the principle of Maglev. fig. 1.1 1.1.1 Magnetic Levitation The "8" figured levitation

Marsden‚ developed his gold foil experiment after his disapproval of the “plum pudding model”. If Thompson’s experiment was correct‚ then all of the alpha particles would travel right through the foil. What Rutherford did was shoot a positively charged helium particle towards a very thin layer of gold foil. He expected the positive particles to move a small distance from their path as they passed through the sea of positive charge. However‚ the ending result of this experiment was that the positive particles
