Britney found an irregularly shaped metal object on the beach that has a mass of 232.5 grams. To determine the volume, she partially filled a cylindrical water bottle and dropped the object in. The water level in the bottle rose by 1.2 cm. The bottle has a diameter of 5 cm. Calculate the density of the metal to determine what type of metal Britney found. Densities, measured in grams per cubic centimeters, g cm3 , for some common metals are listed.

The question is incomplete, the complete question is;

Britney found an irregularly shaped metal object on the beach that

has a mass of 232.5 grams. To determine the volume, she partially

filled a cylindrical water bottle and dropped the object in. The

water level in the bottle rose by 1.2 cm. The bottle has a diameter

of 5 cm. Calculate the density of the metal to determine what type

of metal Britney found. Densities, measured in grams per cubic

centimeter, g

cm3

, for some common metals are listed.

• Copper: 8.86 g

cm3

• Bronze: 9.87 g

cm3

• Silver: 10.5 g

cm3

• Gold: 19.3 g

cm3

Select the word that correctly completes the sentence.

Based on the density of the metal, it is most likely that the metal Britney

found is .

\ copper

\ bronze

\ silver

\ gold

Bronze: 9.87 g

bronze

Explanation:

We know that the volume of the liquid = the volume of the object

This is because the object will cause the liquid to occupy its own volume of the container.

Now; area of the container = πr^2 = 3.142 * (5/2)^2 = 19.635 cm^2

Volume of the liquid = volume of the sold = 19.635 cm^2 * 1.2 cm= 23.562cm^3

Now given that;

Density = mass/volume = 232.5 g/23.562cm^3 = 9.87 g/cm^3

conduction is the transfer of thermal energy (heat in transfer) due to collisions between the molecules in the object. collisions between adjacent atoms and molecules transfer kinetic energy from the warmer to the cooler object. the objects must be in physical contact.
