How many cm 3 are in 0.014 in 3? (1 in = 2.54 cm)
pashok25 [27]

Answer:

0.229 cm³.

Explanation:

The following data were obtained from the question:

Volume (in in³) = 0.014 in³

Volume (in cm³) =?

1 in = 2.54 cm

Next, we shall determine a conversion scale to convert from in³ to cm³. This can be obtained as follow:

1 in = 2.54 cm

Therefore,

1 in³ = 2.54³ cm³

1 in³ = 16.387 cm³

Finally, we shall convert 0.014 in³ to cm³. This can be obtained as follow:

1 in³ = 16.387 cm³

Therefore,

0.014 in³ = 0.014 in³ × 16.387 cm³ / 1 in³

0.014 in³ = 0.229 cm³

Thus, 0.014 in³ is equivalent to 0.229 cm³.

The first step in the two-step process of making a solution is the breakdown of the solute source into ____________."
Troyanec [42]
<h3><u>Answer;</u></h3>

Atomic particles

The first step in the two-step process of making a solution is the breakdown of the solute source into <u>atomic particles</u>.

<h3><u>Explanation</u>;</h3>
  • Solution is a homogeneous mixture of two or more substances uniformly dispersed throughout a single phase
  • <em><u>The liquid component that makes up the largest part of a solution is called the solvent, and the substance that is dissolved is called the solute.</u></em>
  • Unsaturated Solution is a solution that contains less solute than a saturated solution does and that is able to dissolve additional solute, while saturated Solution is a solution that cannot dissolve any more solute under the given conditions

Changes of state are a result of a change in the______of the matter.
jasenka [17]

Answer: -

Kinetic energy.

Explanation: -

Solids have the least kinetic energy and the highest intermolecular force of attraction among the three states of matter.

When heat energy is supplied to the solid, the kinetic energy of the solid particles increases. At some point, the kinetic energy becomes comparable to the intermolecular force of attraction. At that point solids change into liquids.

When further heat energy is given, at certain point the kinetic energy becomes far greater than the intermolecular forces of attraction. At that point it becomes gas.
