Coal is formed from the decomposition of organic matter buried deep underground over millions of years. The process involves the conversion of solar energy into chemical energy through photosynthesis in plants, which is then transformed into potential energy as the organic matter is buried and compressed. Finally, when coal is burned, the potential energy is converted into thermal energy and released as heat.

How is energy conversions involved in the formation of coal?
Coal formation involves the conversion of solar energy into chemical energy through the process of photosynthesis in plants. Over millions of years, this stored chemical energy is further converted into coal through the accumulation and compression of plant matter in the Earth's crust, turning potential energy into stored energy in the form of coal.
Describe the formation of this bond and the total number of electrons in the orbitals of each energy level?
The bond formation involves the sharing of electrons between two atoms. The total number of electrons in the orbitals of each energy level is determined by the number of electrons each atom brings to the bond. In a covalent bond, each atom contributes its valence electrons to form a shared electron pair.
What best describe the enthalpy of formation of a substance?
The enthalpy of formation of a substance is the energy change when a substance is formed from its elements in their standard states. It represents the heat energy released or absorbed during the formation process. A negative value indicates that the reaction is exothermic, while a positive value indicates an endothermic reaction.
How would you compare the formation of positive ions with the formation of negative ions in terms of energy changes?
The formation of positive ions typically requires energy input in the form of ionization energy to remove electrons, whereas the formation of negative ions releases energy in the form of electron affinity when electrons are added. Positive ions have higher potential energy compared to their neutral atoms, whereas negative ions have lower potential energy. Overall, the energy changes involved in forming positive and negative ions are opposite in nature.
Is formation of anions is exothermic process?
The formation of anions is not always an exothermic process. It can be either exothermic or endothermic, depending on the specific elements involved and the overall energy change during the process. It is important to consider the specific reaction and the energy changes associated with it.
What kind of energy conversions are involved when a battery lights a bulb?
Chemical energy to electrical energy.

How much energy is involved in the formation of 5 grams of rust?
The energy involved in the formation of 5 grams of rust can be calculated using the enthalpy of formation of iron(III) oxide (rust), which is -824 kJ/mol. First, convert the mass of rust to moles, then use the molar enthalpy of formation to calculate the energy involved.
When heating a beaker of H20 on a hot plate there are 3 types of energy conversions?
The energy conversions involved are: electrical energy from the hot plate is converted to thermal energy, which heats the water, leading to an increase in its internal energy. As the water heats up, some of this energy is lost to the surroundings as thermal energy.
What are energy conversions?
== ==
Do all energy conversions have thermal energy?
no
What are examples of energy conversions?
Energy converting into another energy
How many energy conversions are there?
3
Are energy conversions important?
Yes.
What is the branch of physio chemical science concerned with heat and energy and their conversions one into the other involved mechanical work?
This chapter of chemistry is called chemical thermodynamics.
Does energy conversions always give off heat?
No, not all energy conversions give off heat. Some energy conversions, such as nuclear reactions and chemical reactions, can produce other forms of energy like light or sound instead of heat.
How does mechanical energy and energy conversions differs?
Mechanical energy is the sum of potential and kinetic energy in an object due to its motion or position. Energy conversions involve changing the form of energy from one type to another, such as transforming mechanical energy into electrical energy. Essentially, mechanical energy is an aspect of energy, while energy conversions involve transformation of energy between different forms.
