Solid to gas (sublimation) is endothermic (takes in heat).In other words:A phase change from the solid state to the gas state is endothermic.Sublimation is endothermic (takes in energy).Heat energy must be provided to make it work.When there is a change of state from a solid to a liquid, a solid to a gas, or a liquid to a gas, at a constant temperature, the process is endothermic NOT exothermic. It requires energy to break the intermolecular forces that keep the molecules together, and that reduces the temperature - heat is taken in.
Methane gas is highly flammable which makes it a good fuel source for gas burning.
Natural gas is chemically known as methane, or CH4. The reaction of burning it produces the following chemical equation: CH4 + 2O2 --> CO2 + 2H2O.
Burning the Charcoal changes the chemical composition of it as burning, or combustion as it is known is an example of a chemical reaction.An example of a combustion reaction is burning Methane (CH4) gas, the chemical equation is:CH4 + O2 -> CO2 + H2OThe reaction is Methane + Oxygen gives Carbon Dioxide and Water.The reaction has changed the chemical composition of the Methane as it has 'turned into' Carbon Dioxide and Water.Burning Charcoal will also produce ONLY Carbon Dioxide and Water.Hope this helps!
The energy release is exothermic although the exothermic reaction is not the goal. The goal is rapid expansion of gases in order to move the pistons away from the cylinder head. Heat is a by product....and an unwanted one at that.
Let's think about what happens in the combustion of methane. Take natural gas for example (methane) used to heat homes, or used in stoves. The product is heat, therefore heat is given off. Therefore EXOTHERMIC.
Burning of methane is an oxidation reaction.

The burning of natural gas is an exothermic process.
Because a chemical change results in the formation of 1 or more new substances and a new compound is created, methane burns with a smokey flame that forms carbon dioxide and water, which makes it a chemical reaction.
If you mean is burning methane comparatively better than releasing it into the atmosphere, then yes it is. Methane is a greenhouse gas, twenty-one times more powerful than carbon dioxide. If methane is released into the atmosphere it works as a greenhouse gas. If it is burnt, it released carbon dioxide instead. Carbon dioxide is also a greenhouse gas, but it is not as powerful as methane. So burning methane is good for the environment.
Methane is the IUPAC name for the main constituent in natural gas (CH4). Methane stores energy in the C-H chemical bonds and this stored energy is readily released as heat through a chemical process known as combustion (burning) which is a largely exergonic reaction.
Methane gas is a compound; you think probable to the combustion of methane.

Yes, exothermic means that there is heat in the "project."
