The short answer is that plants use CO2 as part of the process of photosynthesis, and they do need a source of carbon dioxide in order to survive. The melting and boiling point of water could be the same if you decreased the pressure big time. But land use change (deforestation) is a manmade impact. Why Plants Need CO2 The chemical process known as photosynthesis is how plants generate their own food (in the form of a sugar carbohydrate). Landfill gases are produced when bacteria break down organic waste. Here are some five uses of carbon dioxide: Carbon dioxide is used as a refrigerant. Burying the sky: Turning carbon dioxide into rock Hellisheidi Geothermal Power Plant, located in southwest Iceland, produces electricity and hot water from the Hengill Central Volcano. Infrared technology is used at Geotech as it provides the user with repeatable accuracy, long life and low maintenance. Find out the dangers of CO2, how increased levels of carbon dioxide in the atmosphere can affect the body and how carbon dioxide gas detection can keep you safe. 5 per cent of what we exhale. 64: Gas Density @ 70°F 1 atm (lb/ft3) 0. C o is the carbon dioxide concentration (ppm) in the outside air C r is the carbon dioxide concentration (ppm) in the return air C s is the carbon dioxide concentration (ppm) in the supply air (or mixed air) The total supply air volume is required in order to calculate the approximate cfm of. Drawbacks of Carbon Dioxide The main drawback of carbon dioxide as a refrigerant is its inherent high working pressure. Concrete CO 2 Fact Sheet JUNE 2008 3 CONCRETE CO2 FACT SHEET Introduction Concrete is the most widely used building material in the world because of its beauty, strength and durability, among other benefits.
