Answer:
Density = 2.5 g/cm³ , The metal is aluminium.
Explanation:
Density is defined as the ratio of the mass and the volume
Thus,
Given that:
Mass = 612 grams
Volume = 245 cm³
Thus, Density is:
<u>Density = 2.5 g/cm³</u>
Metals are shiny with high density.
<u><em>The density of aluminium falls is approx 2.6 g/cm³ and not other metal's density falls in this range. </em></u>
<u><em>The metal is aluminium.</em></u>
<u><em></em></u>
Explanation:
The particles are further apart in liquids than in solids so when the lemonade changes from a liquid to a solid, the particles would become closer.
