Argon is a chemical element with the symbol Ar and atomic number 18. It is a noble gas and the third-most abundant gas in the Earth's atmosphere.
Neon is a chemical element with the symbol Ne and atomic number 10. It is a noble gas. Neon is a colorless, odorless, inert monatomic gas under standard conditions.
Xenon is a chemical element with the symbol Xe and atomic number 54. It is a colorless, dense, odorless noble gas found in Earth's atmosphere in trace amounts.
Krypton is a chemical element with the symbol Kr and atomic number 36. It is a colorless, odorless, tasteless noble gas that occurs in trace amounts in the atmosphere.
Helium is a chemical element with the symbol He and atomic number 2. It is a colorless, odorless, tasteless, non-toxic, inert, monatomic gas, the first in the noble gas group in the periodic table. Its boiling point is the lowest among all the elements.
Hydrogen is the chemical element with the symbol H and atomic number 1. With a standard atomic weight of 1.008, hydrogen is the lightest element in the periodic table.
Remixed from Customizable Atom Delux by roman_hegglin. Helium is a chemical element with symbol He and atomic number 2. It is a colorless, odorless, tasteless, non-toxic, inert, monatomic gas, the first in the noble gas group in the periodic table. Its boiling point is the lowest among all the elements.
Sherlock Olmos decides to dig deeper into dark corner of this great house to investigate the suspicious behavior of some chemical elements. The exchange of electrons and the characteristics of hydrogen, fluorine gas, and the noble gases are the primary subjects of his investigation. Part of Chemistry: Solved by Sherlock Olmos Series.
In a gas turbine, the linear motion of gas causes rotors to spin, ultimately creating electricity. The forward rotating blades pump air under high pressure into the combustion chamber where natural gas ignites on contact with the air. At 1,500 degrees Celsius, the stream of gas rushes past the rear turbine blades, causing the entire rotor to spin. A generator transforms that rotational energy into electricity.
Gas hydrates are a significant potential energy source occurring in ocean-floor sediments at water depths greater than 500 meters. The USGS (US Geological Survey) operates a gas hydrates laboratory on its Menlo Park campus. USGS geophysicists Laura Stern and Steve Kirby detail how they study and create gas hydrates in their super-cooled lab.
Anything that takes up space or has mass is matter. Under certain conditions matter can be a solid, liquid, gas or plasma. Different states of matter can be combined in suspensions, and solutions and mixtures can be taken apart. Exploring the physical and chemical properties of matter provides insight into nature and a glimpse at how scientists and engineers use this knowledge to shape our world.
What are the differences between solids, liquids, and gases? In this program, students will investigate real-life examples of the various phases of matter. Colorful animations illustrate how these states differ based on the movement of particles. Other topics covered include plasma, crystalline and amorphous solids, viscosity, freezing, vaporization, evaporation, and condensation.
Chemistry is the science of interacting particles and the various states of matter. Developing a better understanding of the atomic model through experiments with gases, scientists discovered the Ideal Gas Law, developed phase diagrams, and learned about the properties of supercritical fluids. Today's chemists are exploring new ways to control the interactions of atoms, with the goal of making better hydrogen-powered cars and new technologies for the long-term, underground storage of carbon dioxide to reduce greenhouse warming. Part of the series Chemistry: Challenges And Solutions.
Water commonly exists in three different forms: ice, liquid, and vapor. The different phases of water serve as the foundation to teach students about solids, liquids, and gases. Other common everyday examples of solids, liquids, and gases are also featured. Concepts and terminology discussed include: particles, volume, shape, and temperature.
Introduces the concept that everything is made of matter, and examines the three states of matter. Defines and examines a range of solids, liquids, and gases. Uses graphics to show the effects of heat on atoms and molecules in solids. Summarizes each segment.
A teenage narrator presents general information about matter: its characteristics, qualities, properties, and states and changing states. Gives definitions and a review.
Like everyone else, George Huber knows money doesn't grow on trees. But, ask him where gasoline comes from and he won't just tell you, he'll show you. To fully understand, Science Nation recently went with Huber to a local lumber yard in Amherst, Mass. A lumber yard is the perfect place to find cellulose, the key building block in plant cells and the organic material that gives plants their structure. So what does cellulose have to do with gasoline? A lot.
This chapter provides a summary of the material discussed in the previous twelve chapters. Some of the topics reviewed include: the greenhouse effect, global warming, and climatic changes. This chapter also highlights the consequences associated with global warming from major cities to the rural country side. Viewers also explore ways to lessen the impact of global warming and how to adapt to the new climate conditions. Chapter 13 of Air: Climate Change Series.
