Explanation:
When the water droplets are placed in oily surface, oil being non-polar, thus there will not be adhesive force between water and oil.
Thus, surface tension is the factor which is responsible for shape of the water droplets to be spherical. The water molecules are pulled into the spherical shape by the action of the cohesive forces which is acting on the surface layer. As, the medium is totally different outside, the water molecules tend to get the minimum area and thus, forming spherical droplets.
Bedrock is used in the construction of structures, the topsoil is important for the production of crops and the loss of fertile soil is known as desertification.
<h3>Bedrocks, topsoil, and desertification</h3>
- Bedrocks are underlining rocks below soils. They are useful in construction works such as buildings, bridges, etc.
- Topsoils are the topmost portions of soils. They are usually rich in humus and organic matter and are therefore very good for agricultural crop production.
- Desertification is simply the loss of fertile soils and their transformation to barren, unproductive lands. Topsoils are lost and soils are rendered unsuitable for agriculture.

The mass in a chemical reaction remains (mostly) the same.
(except for radiation/nuclear fission, in which mass gets converted into energy)
Answer:
I think it's c
Explanation:
if they were different temperatures then there would be conduction because other thermal energy will conduct to the lower temperature to reach a equal librium
