Answer:

Methane is a chemical compound with the chemical formula CH4, symbolizing one atom of carbon and four atoms of hydrogen. It is a group 14 hydride and the simplest alkaline, and is the main constituent of natural gas. The relative abundance of methane on Earth makes it an economically attractive fuel, although capturing and storing it poses technical challenges due to its gaseous state under normal conditions for temperature and pressure. Methane naturally occurs both below ground and under the seafloor, and is formed by both geological and biological processes. In nature, methane is produced by the anaerobic bacterial decomposition of vegetable matter under water. Methane is important because it can be captured from landfills, can be burned to produce electricity, heat buildings, or power garbage trucks. Methane can also be captured from farm digesters, which are big tanks that contain manure and other waste from barns that house livestock such as cows and pigs. In fact, Jordan Dairy Farms in Massachusetts uses a biodigester to turn cow manure into methane gas, which is used for fuel or turned into electricity.

Classify each statement as an example of adhesion, cohesion, or surface tension. Drag each statement to the appropriate bin. A s
LekaFEV [45]

Answer:

A sewing needle floats when it is placed gently on top of water in a bucket - surface tension

Water molecules ding to plant cell walls - adhesion

A water strider runs across a pond without breaking the surface - surface tension

A drop of water spilled on a table forms a drop on the table, rather than spreading out over the surface - cohesion

Water molecules cling to the side of a beaker - adhesion

Water molecules are attracted to each other - cohesion

Explanation:

The surface tension refers to the tendency of the surface of a liquid to remain unbroken by an external force due to the cohesive property of the molecules of the liquid. Instead of being broken, the surface of the liquid stretches like an elastic membrane.

The adhesive property of a liquid, also known as the force of adhesion, refers to the property of the molecules of the liquid to stick to other molecules while cohesive property or cohesion refers to the property of molecules of liquids to stick to themselves.

Hence,

<u>Surface tension</u>

  • A sewing needle floats when it is placed gently on top of water in a bucket.
  • A water strider runs across a pond without breaking the surface.

<u>Cohesion</u>

  • A drop of water spilled on a table forms a drop on the table, rather than spreading out over the surface.
  • Water molecules are attracted to each other.

<u>Adhesion</u>

  • Water molecules ding to plant cell walls
  • Water molecules cling to the side of a beaker

Which statement about lightning is true?
Vikentia [17]
The best statement that describes lightning is A. It is one of the most dangerous parts of a thunderstorm. Lightning, although often thought to always strike the Earth, can actually occur in the same cloud (intracloud) and between clouds (cloud to cloud). It is caused by the electrostatic discharge between charged particles in the atmosphere.

give an example of a question that can be answered by science &amp; a question that could be better answered by philosophy
never [62]

Answer:

Scientific: "does a sunflower or rose grow faster?"

Philosophy: "does leading by example help guide others?"

Explanation:

the first is scientific because you do experiments to find out the result as a fact.

the other one is philosophical cause it is more so an opinionated question but you can back it up still.
