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

Ethanol
when yeast ferments glucose anaerobically it produces ethanol which is used in drink and can be an alternative fuel source in Brasil it used a lot their engines are adapted to use ethanol as a fuel source
