During chemistry class your teacher challenged you to dissolve four salts as quickly as possible in a specific volume of water.
Each group had to pick a variable to test, a variable that would speed up the dissolving process. Each group had to design an experiment using the steps of the scientific method. The teacher began the experiment with the research question: How can you speed up the dissolution of salt in water. Your group stated: If the water temperature increases, the dissolving time of the four salts will decrease. Your statement can BEST be described as your group's A) hypothesis. B) law. C) theory. D) variable.
A hypothesis is defined as the proposed explanation or assumption that will give an idea what could be the result.
Therefore, when teacher asked what could be done to speed up the reaction then students are actually forming a hypothesis that by increasing the temperature the result be dissolution of all the four salts.
Thus, we can conclude that the statement can BEST be described as your group's hypothesis.
Each component is in balance with the other components. As long as the components are in balance, the ecosystem can remain stable and healthy. Ecosystems may remain stable for many years if the different components are balanced.
Answer:A circle representing a pool is graphed with a center at the origin. Grant enters the pool at point A and swims over to a friend who is located at point B.
