Heat of fusion. (I have no idea what the "propane or water" part is supposed to mean.)
Energy
Burning propane is a chemical change because it involves a chemical reaction where the propane molecules are broken down and rearranged to form new molecules (such as carbon dioxide and water) along with the release of energy in the form of heat and light.
The type of change that releases a large amount of energy per gram of material due to the conversion of matter into energy is nuclear fission or fusion. In fission, heavy nuclei split into lighter nuclei, while in fusion, light nuclei combine to form heavier nuclei. Both processes involve the conversion of mass into energy, as described by Einstein's equation, E=mc², resulting in significant energy release compared to chemical reactions.
If you use a high amount of natural than it is less $ then propane BUT if you use a moderate amount or less than no doubt propane is less. The reason why is even if you do not use any natural gas you still get charged a service fee and tax tax each month, where propane you do not have the extra fees. other than this factor it is almost not possible to figure what is cheaper since the prices for both change rapidly and propane heat is more hot burning. so thus makes it very very hard to figure it out.

Water would require the least amount of energy to change 1kg from a solid to a liquid because it has a lower melting point compared to the other materials listed (ethanol, aluminum, propane).
Heat of fusion.
The change in temperature of a material due to heat energy depends on the specific heat capacity of the material. Different materials have different specific heat capacities, which determine how much heat energy is needed to raise their temperature by a certain amount.
either potential or kinetic
Propane itself does not conduct heat; however, when burnt, it releases heat energy that can then be conducted through a material in contact with the flame or hot surface.
The thermal energy equation in physics is Q mcT, where Q represents the amount of thermal energy, m is the mass of the object, c is the specific heat capacity of the material, and T is the change in temperature. This equation is used to calculate the amount of thermal energy in a system by multiplying the mass of the object by the specific heat capacity of the material and the change in temperature.
When the material does not change, the energy from the light is typically absorbed and converted into heat within the material.
The measure of the amount of heat in a material is its temperature. Temperature indicates the average kinetic energy of the molecules in a material. The higher the temperature, the more heat energy the material contains.
The total amount of energy doesn't change in this case.
Yes, burning propane is a chemical change because it involves a chemical reaction that converts propane (C3H8) into carbon dioxide and water vapor. This reaction releases energy in the form of heat and light.
When a material undergoes stretching or compression, the energy associated with this deformation is stored as potential energy in the bonds between the atoms or molecules of the material. The amount of energy stored is proportional to the amount of deformation applied to the material. This potential energy can be released as kinetic energy when the material returns to its original shape.
The energy needed to change a material from solid to liquid is called the heat of fusion or melting point. This energy is required to overcome the intermolecular forces holding the solid together so that it can transition into a liquid state. The amount of energy needed varies depending on the specific material.
