Question

The following three boxes represent the number of submicroscopic particles within a given volume of a particular substance at different temperatures. Which box represents the greatest density? Which box represents the greatest temperature? 
A)A and C 
B)B and C 
C)A and B 
D)B and A

Quizplus · Accepted Answer

Density is determined by the amount of particles within a given volume, so the box with the highest number of particles (A) has the greatest density. Temperature is determined by the motion of particles, and the box with the highest number of particles moving the fastest (i.e. hottest) is C.
