Carbon: 105 kJ/mol = 105 (kJ/mol) / 0.012(kg/mol) = 8750 kJ/kg Carbon
Material spirits cannot dissolve wax. Wax is a nonpolar substance that is not easily affected by most solvents, including spirits. However, heat can be used to melt wax.
== == Salt lowers the freezing point of water by 32 degrees. If salt is sprinkled onto ice, it causes the ice to melt by a heat transfer. Out of the substances listed, salt would melt ice most efficiently.
The rate of melting of a solid is determined by (1) the difference between the melting point of the liquid and the temperature of the heat source providing the energy for melting, (2) the heat conductivities of the solid and liquid forms of the substance being melted, and (3) the heat of fusion of the substance being melted. If these factors are kept constant, any liquid will melt as the same speed. In practice, under common conditions, water melts more slowly than most other substances, because it has a very high heat of fusion.
A substance with low specific heat capacity and low thermal conductivity would heat up most quickly because it requires less energy to raise its temperature and does not distribute heat effectively. Materials like metals and low-density liquids generally heat up quickly compared to dense solids with high specific heat capacities.
specific heat capacity
Many solids will change into liquids if you heat them, for instance most metals will melt when subjected to heat, ice will become water when heated, some plastics will melt, glass will melt, and most rocks will also melt.

Conduction is the process of heat diffusing through a substance that conducts heat. The less conductive the substance is (like glass, air, or an oven glove), the slower the conduction is. Convection is the movement of heat that occurs when a mass of hot substance physically moves to another location. Both of these mechanisms depend on the presence of a material substance to move heat from place to place, and the efficiency of the mechanism depends on the characteristics of the substance. Radiation is the movement of heat in the form of electromagnetic radiation. It doesn't require any substance in the intervening space to transfer the heat; in fact, it is most efficient when there is NOTHING in the way. That's how heat reaches us from the sun.

The amount of energy needed to change the temperature of a substance is most influenced by its specific heat capacity, which is the amount of energy required to raise the temperature of a given mass of the substance by 1 degree Celsius. Substances with higher specific heat capacities require more energy to change temperature compared to those with lower specific heat capacities. Additionally, the mass of the substance being heated also plays a role in determining the amount of energy needed.
chocolate will most likely not melt at room temp. try using heat in an oven or something.
The order in which the substances will exhibit the highest increase in temperature is C, B, A. This is because substance C has the lowest heat capacity, so it will increase in temperature the most with the same amount of heat added. Substance A, with the highest heat capacity, will increase the least.
Cold water will not melt the ice cube in record time, but hot water will, but salt water will also melt it fast, but if you add both together the ice cube will melt alot fast. Deceasing time alot.
I'm assuming you are talking about sub-atomic particles. The act of melting cannot be applied to particles because melting refers to a change of state of a substance. Substances, whether they be compounds or elemental, are a collection of atoms. These atoms, can be of 3 different states, depending on their temperature. If below the particular substance's melting point, it is solid. Between the melting and boiling point, the substance is liquid, and above the boiling point, the substance is gaseous. The state of the substance refers to the total amount of energy within the substance. Heat is energy, and melting a substance is only adding energy to it. the substance, on a molecular level, does not change when melting occurs. Therefore, melting a particle cannot occur, only energy can be added, which increases movement of the particles.
Yes, a metal spoon can melt with sufficient heat. The melting point varies depending on the type of metal, but most common metals used in spoons such as stainless steel or aluminum have melting points high enough that they will not melt under normal cooking conditions.
Ice will melt faster because when it get to the sun it would already be melting
