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.
all the combustion processes are exothermic because combustion increases the temperature where it occurs.
exothermic the reaction releases heat
Any sort of combustion is exothermic.
Endothermic
Endo draws heat from around it. Exo gives off heat. Example: Ice melting is a endothermic reaction. A match lighting is an exothermic reaction.An exothermic reaction releases heat to it's surroundings. The change in energy is negative. An example is combustion of natural gas.An endothermic reaction absorbs heat, so the temperature of the surroundings drops. The energy is positive. An example is melting ice cubes.
YES ... an Exothermic reaction gives off heat (as the name implies.) The prefix, 'Exo' tells us it's giving off heat whereas a prefix of 'Endo' (as in Endothermic) means it needs to receive heat.
Mrs. Winn. eh?- is called an endothermic reaction.
The reverse reaction is not always endothermic or exothermic, the reverse reaction is the opposite of whatever the initial reaction is, so if the reaction is endothermic, the reverse reaction is exothermic and vise versa.
we can answer this question by studying the words themselves. firstly thermic relates to heat. more to the point endo is a prefix for inside while exo is a prefix for outside. therefore an endothermic reaction is one which absorbs heat while an exothermic reaction is one that emits heat. exothermic reaction releases heat from a system to the environment..i.e. explosion of bomb. while endothermic absorbs heat from the environment to the system..i.e. frying fish.
endothermic but don't know why? As AN crystals are formed the reaction is exothermic. Endothermic when it melts back with water. This is the reason AN is used in cold packs.
A reaction can be classified as either endothermic or exothermic. Endothermic reactions absorb heat from the surroundings while exothermic reactions do the opposite.
Freezing is exothermic.

No, freezing is exothermic as the water loses energy to its surroundings as it freezes.
Only with very high heat. This compound can melt without decomposition.

good question endothermic. Ammonium chloride dissolves in water and makes it cold.
When it shocks its prey its exothermic. A simple way to remember this is Endo- = In and Exo- = Out.
Activation energy is needed to start a chemical reaction. This energy is used to join the reactants together or break them apart. If a reaction is exothermic then it gives energy out. If it is endo thermic then the reaction takes energy in.

Exo- means out Endo- means in. In an Exothermic reaction thermal energy is released (goes out) and in an Endothermic reaction Thermal energy is taken up, transferring into chemical energy (goes in). So, to answer your question, no, the temperature does not go up in both an exothermic and an endothermic reaction.
