Answer:
Water
Explanation:
Acetone has a higher vapour pressure than water because acetone molecules only experience dispersion forces and diploe interactions as the dominant intermolecular forces.
In addition to these mentioned, water molecules are held together by strong hydrogen bonds. Therefore, water has a much lower vapour pressure than acetone and requires greater energy to break these hydrogen bonds and convert the liquid water to gaseous state.
Answer:
a. They must be present in a large geographic area.
Explanation:
Index fossils can be used to determine the age of a rock strata with great precision, but they must be scattered over a large geographic area to be able to be used reliable for this type of measurement. Index fossils typically indicate a certain type of paleoenvironment belonging to a very specific prehistoric period and their formation coincides with the age of the rock layer.
Wind farms are a source of renewable energy found around the world. One of the world's fastest-growing energy sources is wind energy since it has numerous economic benefit.
A renewable and clean energy source is wind power. Utilizing mechanical energy to spin a generator and generate electricity, wind turbines capture wind energy.
In addition to being a plentiful and limitless resource, wind also generates power without consuming any fuel or damaging the environment. The main renewable energy source in the United States is still wind, which aids in lowering our dependency on fossil fuels.
Annually, wind energy helps save 329 million metric tons of carbon dioxide emissions, which is the same amount of emissions produced by 71 million automobiles and contributes to acid rain, pollution, and greenhouse gas emissions.
