Why does gas have a higher enthalpy than liquid?

The gas has the highest internal energy because in the liquid and solid phases a lot of energy is bound up in the bonds between atom or molecules. This energy provides a negative contribution to the internal energy, so these phases have a lower internal energy.

Does gas have higher enthalpy than a liquid?

The arrow to the right of the diagram demonstrates that these three phases have different enthalpies: gas has the highest enthalpy, liquid has an intermediate enthalpy, and solid has the lowest enthalpy.

Why is gaseous fuel is better than other fuels?

-It has high calorific value so it is more efficient for engines. -It produces a great amount of heat energy with combustion of only one kg fuel. -It does not leave any ash on burning unlike the solid and liquid fuels. Hence we can say that the gaseous fuels are better than the solid or liquid ones.

What are the advantages of gaseous fuels over liquid fuels?

Liquid and gaseous fuels do not leave any residue after burning. 4. Liquid and gaseous fuels have higher calorific values than the solid fuels. In other words, for a given mass of the fuel, liquid and gaseous fuels produce more heat.

Would enthalpy change be the same if gaseous water was produced instead of liquid water?

If the physical states are different, there will be a different enthalpy change. In the first, gaseous water is formed, and in the second, liquid water is formed; the difference between their enthalpy changes reflects the difference in energy content between a gas and a liquid.

Why does gas have the highest energy?

Because gas particles move around the most – they have the most energy. the water particles move around more. the distances between the particles increases. soon the particles have enough energy to turn into a gas.

Why are gaseous fuels better than the solids and liquid ones?

The higher the calorific value of a fuel, the more is its efficiency. The calorific value of gaseous fuels are more. When a gaseous fuel burns, it gives off a great deal of energy. And unlike other solid and liquid fuels it does not leaves any ash.

What are the disadvantages of gaseous fuels?

Disadvantages of Gaseous fuels :

• Very large storage tank needed for them.
• They are highly inflammable, so chances of fire hazards are high in their use.
• They are more costly as compared with solid and liquid fuels.

What is the disadvantage of gaseous fuel?

Which of the following is a disadvantage of gaseous fuel? Explanation: The particles in gaseous fuels are separated from each other, due to which their combustion becomes very easy. This increases the inflammability of the gaseous fuel. Special care should be taken to avoid fire hazards.

What is gaseous fuel advantages and disadvantages?

They burn without heat loss, due to convection currents. They burn in slight excess of air supply. They are free from solid and liquid impurities. Complete combustion without pollution is possible due to the uniform mixing of air and fuel.

What occurs when the products have less enthalpy than the reactants?

In exothermic reactions, the products have less enthalpy than the reactants, and as a result, an exothermic reaction is said to have a negative enthalpy of reaction. This means that the energy required to break the bonds in the reactants is less than the energy released when new bonds form in the products.
