Why did evaporation cause the temperature to drop for each liquid? Explain exactlywhat happens on a molecular level to the parti

cles and the energy during the evaporation process.
Chemistry

erik [133]3 years ago
4 0

Explanation:

The conversion of the liquid to the vapor below boiling temperature of liquid is called evaporation.

Each molecule in liquid phase is attracted to other molecules in liquid by the intermolcular forces of attraction. When the process of evaporation starts, the molecules has to change the phase from the liquid to vapor for which they have to break all these interaction so that they can escape. The molecules with sufficient energy to do so only can do this. These molecules with high energy leave and remaining molecules are ones which did not have the enough energy to evaporate. Thus, average kinetic energy of molecules in liquid left behind is lower than it was before. <u>So, evaporation is a cooling process because heat of the molecules was used up for breaking hotter molecules out into gas phase and the left ones are cooled. </u>

Assuming all other conditions remain the same, which of the following will cause an object's density to increase?
Elanso [62]

Taking into account the definition of density,  assuming all other conditions remain the same, increasing mass will cause an object's density to increase.

Density is defined as the property that matter, whether solid, liquid or gas, has to compress into a given space. That is, density is a quantity referred to the amount of mass contained in a given volume.

Density is an intensive property since it does not vary with the amount of substance.

Since density is the relationship between the mass and the volume of a substance, its calculation is defined as the quotient between the mass of a body and the volume it occupies:

density=\frac{mass}{volume}

In the previous expression it can be observed that the density is inversely proportional to the volume: the smaller the volume occupied by a certain mass, the greater the density.

On the other hand, density is directly proportional to mass: the greater the mass, the greater the density.

Finally,  assuming all other conditions remain the same, increasing mass will cause an object's density to increase.

Some fuel cells are powered by hydrogen. Scientists are looking into the decomposition of water (H2O) to make hydrogen fuel with
skad [1K]

A.  Decomposing water requires a high activation energy.

Explanation:

In decomposing water to release hydrogen gas to make fuel cells, the process requires a very high activation energy.

                             2H₂O ⇆ 2H₂  + O₂

 This is the overall reaction. O-H must be broken to release free hydrogen to produce hydrogen gas.

The O-H bond is a very strong force of attraction that requires a high activation energy to overcome.

  • The activation energy is the energy barrier that must be overcome before a reaction takes place.
  • The sun is a renewable source of energy.
  • Water decomposition produces useful oxygen gas needed by all life for cellular respiration.
