The molecules of propane gas slow down as the gas is compressed. As a result, during liquefaction, a large portion of the kinetic energy lost by the propane molecule is released into the environment.
Thus, as we transition from a gas to a liquid, our molecules get closer to one another. And because our particles are moving from being far apart to being close to one another in the liquid form, we will see an increase in the intermolecular forces as our molecules become more attracted to one another. And since we're effectively creating bonds here, energy will be released. And utilizing Barth's barf, we may recall this. When bonds are broken, energy is absorbed. However, energy is released as bonds are created. We are now creating stronger ties as a result. We are therefore expending energy.
<h3>
What is liquefaction?</h3>
In physics and chemistry, the process of a solid turning into a liquid (also known as melting or condensation) is referred to as liquification. Melting point is a term used to describe the temperature and pressure at which a solid becomes a liquid (sometimes referred to as the liquefaction point).
<h3>
What is Kinetic energy?</h3>
Kinetic energy is the name for the force that pushes an object in motion. Its basic nature is that of a moving mass's energy. As a scalar quantity, kinetic energy merely conveys the amount of an event rather than its direction. It is unimaginably good.

Blank #3: 1 (see explanation)
<h3>Explanation</h3>
Both the ammonium ion and the sulfate ion contain more than one atom in each ion. The two species are thus <em>polyatomic</em>. The chloride ion , for example, is <em>monoatomic</em>.
Superscripts above formulae of the ions indicate their charge. Each ammonium ion carries a positive one (+1) charge. Each sulfate ion carries a charge of negative two (-2).
Ammonium sulfate is an ionic compound. A sample of this compound contain myriads of ammonium ions and sulfate ions. The ions are packed in three-dimensional lattices. Thus unlike water, ammonium sulfate does not exist as molecules in nature.
Assuming that the second and third blanks refers to a formula unit, rather than a molecule, of ammonium sulfate. The empirical formula of ammonium sulfate gives the minimum whole-number ratio between the two ions in a sample.
Charges shall balance between the two ions. Ammonium ions are of charge +1. Sulfate ions are of charge -2. The sample shall thus contain two ammonium ions for every one sulfate ion.
The empirical formula of ammonium sulfate is therefore .
There are thus two ammonium ions and one sulfate ion in each formula unit of ammonium sulfate.
