What is Freon 11 used for?

Freon 11 was also used as a propellant for aerosols until the 1970s, when it was banned because of its harmful effects to the ozone layer. Most equipment produced in the '90s that used Freon 11 is being replaced by its more environmentally-friendly substitute, R-123. Even though it is less harmful, even R-123 is set to be discontinued in 2020.

How are sills formed?

A sill is an intrusive rock formation. These formations occur when magma solidifies underground and then intrudes into the overlying rock formation. They are distinct from similarly formed domes and dikes because sills are horizontal to the surface.\nA sill is tabular or sheet-like in shape because the magma intrudes in a horizontal formation before solidifying. The texture of a sill is a function of the time it takes for the magma to cool and solidify. In general, the longer it takes the magma to cool, the greater the size and extent of the formation. If a sill cools quickly, the texture of t..

What does an IQ of 120 indicate?

Edublox explains that the intelligence quotient scores are classified into seven ranges. A score of below 70 means that the person is considered extremely low-functioning. Scores between 70 and 79 are thought to be borderline. People who score between 80 and 89 are termed "low average." Scores in the middle of the scale, between 90 and 109, are considered average. Edublox notes that people in the average range usually hold jobs as laborers, miners, farmhands, carpenters, cooks and machine operators. People with scores between 110 and 119 are considered to be high average. These people typicall..

What is the temperature of the planet Uranus?

Uranus is an ice giant that does not consist of a solid surface. Its atmosphere has a composition that is mostly clouds made up of gases, such as hydrogen, helium and methane. Scientists believe that underneath this cloud layer there may be a liquid water layer and ice.\nUranus’ name comes from the Greek god Ouranos. William Herschel discovered this planet in 1781. Uranus has 13 rings and many moons, including Oberon and Miranda. Its period of revolution around the sun is 84 Earth years.

How do fungi feed?

Different fungi take different forms and are found in different contexts, but they are all united by the fact that they absorb nutrients. Fungi differ from plants in that they do not have chlorophyll or other means of manufacturing nutrients for themselves. Because they must have some sort of host from which to feed, fungi are dependent on other organic beings for survival. The fungi that digest dead organic matter serve an important function by assisting with the decomposition of things like fallen trees and leaves, and this keeps the life cycles of forested areas running smoothly.

What is a narrow waterway connecting two larger bodies of water?

Many straits are strategically important. One such example is the Strait of Hormuz. At 21 to 60 miles wide, it connects the Persian Gulf with the Arabian Sea and the Gulf of Oman. It is one of the major passages through which oil is transported out of the Middle East, and Oman and Iran share territorial rights to it as of 2015.

What are some projects that incorporate magnetic levitation?

Magnetically levitated trains suspend themselves above the tracks using a magnetic field to eliminate friction, achieve higher speeds and offer a safe method of transport. Magnetic levitation technology introduced in classical heart pumps created a smaller device with low power usage and an extended reliability. Special sensors use magnetic levitation to suspend liquids in the air and measure the density and content. The first patent for a "levitating transmitting apparatus" was given to Emile Bachelet in 1912.

What is a green pigment that traps energy from sunlight?

During the daytime, when sunlight falls on green leaves, it traps the solar energy and converts it into simple carbohydrates such as glucose and starch. Thus, it helps to convert solar energy into chemical form.\nThis process is called photosynthesis and takes place only in green plants. For photosynthesis to take place, carbon dioxide and water vapor are also necessary. Oxygen is given out during the process of photosynthesis.

What is the distance between Saturn and Uranus?

Due to the of nature planetary orbits, the distance between planets can vary by an incredible amount. For this reason, it is common to work with average distance measurements. The average distance between the Sun and Saturn is 9.54 astronomical units, while the average distance between the Sun and Uranus is 19.14 astronomical units. Subtracting 9.54 from 19.14 yields the 9.6 astronomical unit value for the average distance between Uranus and Saturn.

Where does Merino wool come from?

The especially fine and soft Merino wool has had high economic value around the world since the 14th century. The fineness of different Merino wool results from Merino cross-breeds and continually breeding Merino sheep with the most desirable quality fleeces. The cross-breeding and spread of the original Spanish Merino breed resulted in a dilution of purebred Merino stock. Few flocks in the world legitimately claim purebred Merino strains descending from the Spanish Merino flocks.
