The higher the energy density of a fuel, the greater the amount of energy it has stored.
<h3>What is the energy density?</h3>
The energy density of a fuel is defined as the amount of energy it possesses per unit volume or per unit weight.
<h3>Characteristics of the energy density</h3>
- It is the amount of energy accumulated in an energy vector per unit volume or mass.
- In general, higher density energy sources and carriers are preferable, as many end uses require concentration of such energy.
- The packaging of energy in liquid hydrocarbons is the one with the highest energy density, that is, the highest energy per volume unit, hence its high use in the transportation sector.
Therefore, we can conclude that in general, fuels, especially low molecular weight fuels, have high energy densities.

Answer:
<h2>
32°F
/0°C
</h2>
Explanation:
At what temperature does the melting point occur?
32°F
/0°C
(32°F − 32) × 5/9 = 0°C
At temperatures above 32°F (0°C), pure water ice melts and changes state from a solid to a liquid (water); 32°F (0°C) is the melting point. For most substances, the melting and freezing points are about the same temperature.
Is Melting Point affected by temperature?
Melting point, the temperature at which the solid and liquid forms of a pure substance can exist in equilibrium. As heat is applied to a solid, its temperature will increase until the melting point is reached. More heat then will convert the solid into a liquid with no temperature change.
The element cesium forms a positive ion with the charge +1 . The symbol for this ion is Ce⁺, and the name is cesium ion. The number of electrons in this ion is 54.
<h3>What group does the element cesium belong to in the periodic table?</h3>
Cesium belong to the Group 1A of the periodic table.
Group 1A elements are known as alkali metals.
The alkali metals react with water to form alkalis. They form ions with a positive charge of +1 by the loss of an electron.
In conclusion, cesium is an alkali metals it belongs to group 1A of the periodic table. It forms a positive ion with a charge of +1 by the loss of an electron.

<span>If 1 kj/mol is 0.239 kilocalories/ mol, then 941 kj/mol is 224.904 kcal/mol or 224904 cal/mol. They both are energy units. The joule is the International System unit. It is ultimately defined in terms of the meter, kilogram, and second. One calorie is the amount of heat required to raise the temperature of 1 gram of water by 1°C</span>
