Key Concepts

Here are the essential concepts you must grasp in order to answer the question correctly.

Hypothesis vs. Theory

A hypothesis is a testable prediction about the relationship between variables, often based on limited evidence. In contrast, a theory is a well-substantiated explanation of an aspect of the natural world, supported by a body of evidence and repeated testing. The distinction lies in the level of support and validation, with theories being more robust than hypotheses.

Scientific Method

The scientific method is a systematic approach to inquiry that involves making observations, forming hypotheses, conducting experiments, and drawing conclusions. This process allows scientists to test hypotheses and develop theories based on empirical evidence. Understanding this method is crucial for evaluating the strength of scientific claims.

Evidence in Science

In scientific research, evidence refers to the data and observations collected through experiments and studies that support or refute a hypothesis or theory. The strength of a hypothesis is determined by the quality and quantity of evidence available, with a well-supported hypothesis potentially evolving into a theory if it withstands rigorous testing.

Textbook Question

You are assigned the task of separating a desired granular material with a density of 3.62 g/cm3 from an undesired granular material that has a density of 2.04 g/cm3. You want to do this by shaking the mixture in a liquid in which the heavier material will fall to the bottom and the lighter material will float. A solid will float on any liquid that is more dense. Using an Internet-based source or a handbook of chemistry, find the densities of the following substances: carbon tetrachloride, hexane, benzene, and diiodomethane. Which of these liquids will serve your purpose, assuming no chemical interaction takes place between the liquid and the solids?
