Solar Energy is the answer
Physical changes only affect the appearance of an object. While chemical happens to the chemical make up and cannot be reversed. Think of it this way- physical change is like hair tint , it wears off- chemical is like permanent hair dye, it's permanent.
Population growth decreases as the population density increases. This may be true for non-human populations but our species has developed the ability to modify the environment to sustain a huge population size.

Answer:
4.78 g/cm³
Explanation:
Density is expressed as mass per unit volume:
D = m/V
D = (24.02 g) / (5.02 mL) = 4.78 g/mL
The density should be expressed in g/cm³, so mL must be converted to cm³. The conversion ratio is 1 mL = 1 cm³.
(4.78 g/mL)(1 mL/1 cm³) = 4.78 g/cm³
