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.
Predators are animals that hunt and kill other animals for food. Both carnivores and omnivores can be predators. The other classification of carnivores and omnivores is scavengers, which means they feed off of animals that are already dead. Predators include lions, sharks and eagles.
