Matter and Measurement

In the universe, there is matter, energy, and void space. The universe contains energy and void space. The definition of matter can be considered as something which possesses mass and consumes space. Chemistry is that branch of science which deals with the study of matter. Under chemistry, nature, composition, and the changes occurring to matter are discussed.

3. How would you expect the density of the gummy bear to change if vOu soakod it in

Expert Solution

Step 1

Density does not depend upon amount of substance used thus is an intensive physical property which is calculated by dividing mass by volume and is formulated as

$ρ (density) = \frac{m (mass)}{V (volume)}$
