A reaction in which heat is given out.
No because in an exothermic change energy is released not taken in. Melting would be an example of exothermic change.
It can be either. Some exothermic processes, such as combustion, are chemical changes while others, such as condensation, are physical.
Chemical, since it doesn't turn back.
Jack recorded the exothermic change as the reaction progressed
endothermic and exothermic
they are actually considered exothermic change because they release energy.
No, it is a physical change, not a chemical reaction.
an exothermic process
Exothermic reactions. E.g. combustion, oxidation
Chemical change and exothermic. In this reaction, hydrogen and oxygen undergo a chemical change to form water, releasing energy in the form of heat and light.
You can determine if a chemical reaction is exothermic by measuring the temperature change of the surroundings. If the temperature increases during the reaction, then it is exothermic. Additionally, you can look for the release of heat or light during the reaction as indicators of an exothermic process.
It depends on whether or not the chemical reaction is exothermic or endothermic. If exothermic, then yes, energy is released. If endothermic, then no, energy is absorbed, not released.
