Oh, okay, i understand it now. :) Thanks!

vocaloid · Answer

let's look at a first:

a. The material expands

since density = mass/volume, and the material is expanding, that means the volume is increasing while mass is staying the same

vocaloid · Answer

when volume increases, density decreases
