D. A liquid becoming gas

Cations are formed when atoms lose electrons, resulting in a net positive charge.

Generally, cations are formed by atoms of metals. Metals tend to have relatively low ionization energies, allowing them to easily lose electrons and form positively charged cations. Examples of metals that commonly form cations include sodium (Na⁺), calcium (Ca²⁺), iron (Fe²⁺ or Fe³⁺), and aluminum (Al³⁺), among others. It is important to note that not all metals form cations, as some metals can exhibit variable oxidation states or form anions in certain compounds.

Hence, Cations are formed when atoms lose electrons.

Answer:

positively charged atoms

Explanation:

• The buoyant force on an object depends on the volume of the object that is underwater.
• The buoyant force on an object increases as it is lowered into water because more volume of the object is displaced by water, which increases the buoyant force.
• The buoyant force on an object is equal to the weight of the water it displaces.
• When the buoyant force on an object is equal to the weight of the water it displaces, the object will float and remain suspended in the water without sinking or rising.

5A. The volume of the rectangular object is 10 x 5 x 20 = 1000 cubic centimeters.

5B. The density of the object is 800 grams / 1000 cubic centimeters = 0.8 g/cm3.

5C. The object will sink in water because its density is greater than the density of water, which is 1 g/cm3.

• Iron will sink in mercury because its density is less than the density of mercury, which is 13.5 g/cm3.
• It is incorrect to say that heavy objects sink in water because an object's density, not its weight, determines whether it will sink or float in water.
• Steel ships float because their shape allows them to displace a volume of water that is greater than their own weight, which creates a buoyant force that supports the weight of the ship and keeps it afloat.
• The rock will sink in mercury because its density is less than the density of mercury, which means that it is more dense than the liquid it is placed in.

What is buoyancy and density?

Buoyancy is the upward force exerted on an object immersed in a fluid (liquid or gas), which opposes the object's weight. This force is caused by the difference in pressure between the top and bottom of the object.

Density is a measure of how much mass is contained in a given volume of a substance. It is typically expressed in units of kilograms per cubic meter (kg/m³) or grams per cubic centimeter (g/cm³). The density of an object can determine whether it floats or sinks in a fluid, with objects that are less dense than the fluid rising to the surface and those that are more dense sinking to the bottom.

To find the volume of a 240-piece of cork, we need to know the mass or total weight of the cork. The given information only states the density of the cork, which is 0.24, but it does not provide the mass directly.

Density (ρ) is defined as the mass (m) of an object divided by its volume (V):

Density (ρ) = Mass (m) / Volume (V)

Given: Density (ρ) = 0.24 g/cm³ (as 0.24 is equivalent to 0.24 g/cm³ for this case)

Mass (m) = 240 g

We need to rearrange the formula to solve for the volume (V):

Volume (V) = Mass (m) / Density (ρ)

Volume (V) = 240 g / 0.24 g/cm³

Volume (V) = 1000 cm³

So, the volume of the 240 grams of cork is 1000 cubic centimeters (cm³).
