Which of these does a fire need to burn quizlet?
Terms in this set (4) A rapid reaction between oxygen and fuel. A material that releases energy when it burns. What are three things necessary to maintain a fire? Three things necessary to start and maintain a fire are fuel, oxygen, and heat.
Which of these do plants need to make food argon carbon dioxide nitrogen or oxygen?
Plants need carbon dioxide to make food during the process of photosynthesis. Nitrogen is used to make living matter. However, animals and plants cannot use it directly from the atmosphere. Plants absorb nitrates from the soil.
What are the major chemical constituents present in air?
The constituent elements are primarily nitrogen and oxygen, with a small amount of argon.
What is the most common container used to collect fire debris evidence?
All fire debris evidence must be submitted in vapor-tight containers such as glass “mason” jars with screw-on lids or lined metal cans with friction fit lids. Unlined metal cans are not acceptable containers. Paper and/or plastic bags are not vapor-tight containers and will not be accepted by the laboratory.
What is the thin layer of gas that surrounds the Earth?
the atmosphere
We live at the bottom of an invisible ocean called the atmosphere, a layer of gases surrounding our planet. Nitrogen and oxygen account for 99 percent of the gases in dry air, with argon, carbon dioxide, helium, neon, and other gases making up minute portions.
What elements are in air we breathe?
The air in Earth’s atmosphere is made up of approximately 78 percent nitrogen and 21 percent oxygen. Air also has small amounts of lots of other gases, too, such as carbon dioxide, neon, and hydrogen.
Do plants breathe in carbon dioxide and breathe out oxygen?
One of the first things taught in biology class is that animals breathe in oxygen and exhale CO2, while plants take in CO2 during the day and release oxygen. In a process called “photosynthesis,” plants use the energy in sunlight to convert CO2 and water to sugar and oxygen.
Which gas is inhaled by plants?
oxygen
Plants do breathe – they give out carbon dioxide and absorb oxygen from the air that surrounds them.
