Metals and Non Metals Class 8 Notes, Question Answers

Why are bells made of metals? Answer: Nitrogen and oxygen are gaseous non-metals. Bromine is a non-metal which is liquid at room temperature. Low Melting and boiling point: Non-metals are loosely packed and therefore, less heat is required to melt or boil them. Hence, non-metals possess low melting and boiling points, except graphite. Carbon (graphite) is a non-metal but possesses high Get price

Sublake Settlements for Mars

Filling this with an oxygen/nitrogen gas mixture would provide a habitat of equal size to that discussed above. The pressure under 20 m of ice (density = 0.92) is 0.7 bar, or 10.3 psi. The roof of the dome is under 8 m of ice, whose mass exerts of compressive pressure of 0.28 bar, or 4.1 psi, leaving a pressure difference of 6.2 psi to be held by the strength of the ice. The tensile strength Get price

How Does Boyle's Law Apply to Scuba Diving?

Ascend Slowly - A diver's body absorbs compressed nitrogen gas while he dives. As he ascends to a depth with less water pressure, this nitrogen gas expands according to Boyle's Law. If a diver does not ascend slowly enough for his body to eliminate this expanding nitrogen gas, it can form tiny bubbles in his blood and tissue and cause decompression sickness. Why a Constant Temperature Is Get price


Oxygen, a colorless, odorless, tasteless gas essential to living organisms, being taken up by animals, which convert it to carbon dioxide; plants, in turn, utilize carbon dioxide as a source of carbon and return the oxygen to the atmosphere. Oxygen forms compounds by reaction with practically any other element. Get price

A review of gas prospectivity: Otway region

Low gas contents were a feature of the drilling and testing undertaken by Eastern Star in the Bells Beach Syncline and the Parwan Trough. Both the Anglesea and Maddingley coal seams in these areas produced low gas contents; most could not be measured as the volumes were too low. Hypothetical development scenarios Get price

7 Spray Painting with Nitrogen

Nitrogen, a widely used industrial gas, is produced in liquid and gaseous forms by means of: A) cryogenic separation of air: compression and decompression of air until it liquefies. Using different boiling points, the components of air are separated in a distillation column. B) P.S.A. (Pressure Swing Adsorption): generators having minimum two absorbers filled with molecular sieve (CMS Get price

gas is expected to have a constant value of PV, as shown by the dotted line. CO2 shows the largest change in PV, and this change is actually quite small: PV changes from about 22.39 Latm at 0.25 atm to 22.26 Latm at 1.00 atm. Thus Boyle's Law is a good approximation at these relatively low pressures. Exercise 2 Boyle's Law I . Sulfur dioxide (SO2), a gas that plays a central role in Get price

Nitrogen cap a 'blunt instrument'

The government's national 190kg/ ha/year cap on nitrogen has rung alarm bells in the rural sector – not necessarily because of the number itself but because it heralds a much-feared shift towards input controls.

Nitrogen Oxide Pollution May Spark Seeds' Growth

Two ecologists have learned that the seeds of a common California wildflower can be prompted to germinate by exposure to nitrogen oxides, gases produced by both natural wildfires and motor vehicles and power plants. The finding, reported on page [1248][1], helps explain why the flower springs up so quickly after brush fires. It also raises a provocative question: Could nitrogen oxides in air Get price

Solved: _____Seymour And Hetz (2011) Found That These

_____Seymour and Hetz (2011) found that these spiders only needed to resurface to fill the diving bells with air once a day because the bells were acting like a gill, extracting O2 from the surrounding water. How might that be possible? A) The nitrogen gas in the trapped air causes a diffusion gradient and O 2 diffuses into the diving bell as a result of that nitrogen gradient. B) As the Get price
