Answer:
in days
Explanation:
A short term environmental change refers to changes in the environment that happens within a short period of time, for example, flooding, drought, volcanic eruptions etc. In contrast to short term environmental change, long term environmental change takes place over a long period of time hence species have a longer time to adapt to it. Short term environmental changes may or may not be caused by humans. An example of a short term environmental change caused by humans is oil spillage. Short term environmental changes may lead to the the migration of species from the ecosystem.
Short term environmental changes usually occur within a very short time. The greatest time frame in which a short term environmental change can occur is in a matter of days. Only longterm environmental changes span hundreds and thousands of years.
Hello!
The substances, ordered according to their dissolving time in water, are the following
Sugar Cubes > Granulated Sugar > Powdered Sugar
The difference between these substances is the degree of order. According to collision theory, for a substance to be dissolved, successful collisions between solvent molecules and solute molecules need to happen. as molecules are more ordered, successful collisions are less likely to happen, because atoms are fixed into a crystalline structure.
When the molecule is less ordered, successful collisions are more likely to occur, as the atoms can be impacted from different sides and aren't fixed into a given position.
As the degree of order increases, the dissolving time in water will be higher too, as more time would be required for successful collisions to happen. The most ordered substance is sugar cubes, followed by granulated sugar and powdered sugar, and that order is the same as the order for dissolving time.
Have a nice day!
