The density of gasoline is 0.7 g/cm3, and the density of water is 1 g/cm3. Thus the mass of the gasoline is 55*0.7 = 38.5g and the mass of the water is 60g.
Combining the 55 cm3 and 60 cm3 of substances with the aforementioned masses yields a volume of 55+60 = 115cm3 and a mass of 38.5+60 = 98.5g. The density is therefore 98.5/115 = 0.86 g/m3.
Explanation:
B. The light bends in the water causing the straw to look different.
This happens due to the refraction of light.
Democritus because of Greek atomism. In the 5th century BCE, Leucippus and his pupil Democritus proposed that all matter was composed of small indivisible particles called atoms.
As temperature increases, the molecules and atoms move faster. :^)
<span>Well, for one, they have the same amount of electrons in the outmost shell: Group 1 has 1, Group 2 has 2 etc...They all share similar chemical properties, for example Group 6 (?) S and Se both are acidic oxides.</span>
