When there's a smoking hole in your lab bench. (Exothermic reactions give off heat, so a temperature rise after the reagents are mixed is usually a pretty good indication.)
The change in color indicates that a chemical reaction has taken place.
An endothermic reaction is a chemical reaction in which more energy is taken in than given off. This means that energy is absorbed from the surroundings during the reaction, causing a decrease in temperature. An example of an endothermic reaction is the reaction between baking soda and vinegar.
The terms "endothermic" and "exothermic" refer to whether a chemical reaction absorbs or releases heat, respectively. In an endothermic reaction, heat is absorbed from the surroundings, while in an exothermic reaction, heat is released into the surroundings.
Dark reaction is taken place. It is the light independent reaction
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.

During an exothermic reaction.
exothermic
An endothermic reaction is a chemical reaction in which more energy is taken in than given off. This means that energy is absorbed from the surroundings during the reaction, causing a decrease in temperature. An example of an endothermic reaction is the reaction between baking soda and vinegar.
If energy is released as a result of a process, an exothermic change has taken place. If a constant input of energy is required to drive a physical or chemical change, the change is described as endothermic.
An endothermal (or endothermic) process is the name of the process in which heat is taken in. In an exothermal (or exothermic) process, heat is released.
The terms "endothermic" and "exothermic" refer to whether a chemical reaction absorbs or releases heat, respectively. In an endothermic reaction, heat is absorbed from the surroundings, while in an exothermic reaction, heat is released into the surroundings.
Dark reaction is taken place. It is the light independent reaction
Exothermic Because exothermic means heat is released and endothermic means heat is taken in.
An exothermic reaction releases energy, usually to the surroundings. There is a net loss of energy from the reactants. However, exothermic reactions also need a little energy to get started, but this is less than the eventual amount given out. An endothermic reaction takes in energy, also usually from the surroundings. There is a net gain of energy into the reactions. Again, a little energy is lost, but this is hardly anything compared to the amount taken in.
Energy can either decrease or increase during a chemical reaction depending on whether it is an exothermic reaction (energy is released) or an endothermic reaction (energy is absorbed). In an exothermic reaction, energy is released in the form of heat, and in an endothermic reaction, energy is absorbed from the surroundings.
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.
