If an umbrella place Venus in a shadow and the temperature could fall to the time of the hot springs at yellowstong we could seed it with extremeophones whomight thrive on the carbon dioxide atmosphere. It seems possible we could habitat venus in a few thousand years ??
The concept here is too deprive the fire from oxygen which fuels the fire. One the chemical is denser then air so it will push the air away from the fire and will smuther the flame underneath
It depends on the source of the fire and the type of fire extinguisher. There are 4 classes of fire A - Standard combustable like paper and wood B - Liquids like oil and gas C - Electrical D - Metals (Magnesium, etc.) (Generally the only way to put out is to smother) Fire extinguishers are classified by what type of fire they can be used on. The main types are Water - used on type A CO2, halon, (displacing gasses) - used on types A and C, can be used on type B to some effect AFFF (or similar agent) - used on type B, can also be used on type A PKP (or similar chemical agent) - used on types A, B, and C (D?) Generally there are three things that make a fire burnfuel, heat, oxygen. Take away one of them and the fire will go out (at least until it is reintroduced). Water takes out heat. CO2, AFFF, etc. are used to deprive fire of oxygen PKP - can't really explain the chemical reaction that takes place, but it works.
Lions - Heel Tigers - Heel Giraffes - Face Sharks - Face Wolves - Heel Elephants - Face Hippos - Heel Grizzly Bears - Heel House Cat - Face Dog - Face Whales - Face Dolphins - Heel Polar Bears - Heel Crocodiles - Heel Ostrich - Heel Eagles - Heel Squirrels - Face Bats - Face Gorillas - Face Coyotes - Heel Pandas - Face Its really impossible to legit answer these questions. Like for example, there are hundreds/ thousands of species of Shark. Yet only like 4 of them are Vicious. Same goes for whales. The only one that is vicious is the Killer whale. Make da list more specific next time plox.
the fire is extinguished.
One of several things that all achieve the same effect: the fire no longer has sufficient oxygen to continue burning. Some extinguishers simply spray water on the fire. This is less common these days as a significant number of indoor fires are chemical or electrical in nature, and spraying water on these is generally a bad idea and can in some cases make things significantly worse. The other main type uses a chemical of some kind, frequently based on either carbon dioxide or nitrogen, neither of which burn very well. These chemicals simply take the place of the oxygen in the air, effectively smothering the fire the same way a wet blanket can for smaller fires. Though fire extguishers generally contain non-toxic chemicals, inertness being a primary goal for any fire-suppressant, that doesn't mean they're good for you, so don't go shooting anyone with them.
