Consider the following assumptions about the structure of matter on the microscale ("molecular scale) as you answer the remaining questions. •I. All matter is made of small particles. •II. The macroscale ("real world") behavior of materials can be related to the behavior and characteristics of the individual particles that make up the matter. •III. Attractive "forces" exist between individual particles (particles are "sticky" towards each other). Question 4: Gases can be compressed easily. What does this imply about the amount of space that must be present between the individual gas particles? A. lots of space between gas particles B. little to no space between gas particles C. nothing about the space between gas particles can be inferred.
