An endothermic change requires heat, and an exothermic change releases heat.
In an exothermic reaction, energy is released heat and temperature increases. In an endothermic reaction, energy is absorbed and the temperature decreases.
In exothermic,energy exits but in endothermic, energy enters
Freezing is exothermic, as the substance that is freezing loses energy to its surroundings.
Evaporation is an endothermic process because absorb energy.
An endothermic phase change is when the substance absorbs energy from its surroundings (melting, vaporization).In an exothermic phase change the substance releases energy to its surroundings (freezing, condensation)..
An endothermic reaction absorbs heat. It cannot proceed without the addition of heat. An exothermic reaction releases heat. Since heat causes chemical reactions to go faster, an exothermic reaction can "feed on itself" and get out of control, releasing damaging amounts of heat and, if proceeding in a closed container, causing an explosion.
it is an endothermic
It is an exothermic change
An endothermic change requires heat, and an exothermic change releases heat.
exothermic- because exothermic gives off heat and endothermic is cold
endothermic change
Any reaction categories into exothermic and endothermic based upon change in enthalpy of reaction. If difference in enthalpy of product and reactant comes positive value then it is termed as endothermic and if it is negative value then exothermic reaction. Usually, vaporisation is considered as exothermic due to release in energy.
A solid is itself neither endothermic or exothermic. However the phase change from liquid to solid will likely be exothermic.
The difference between endothermic and exothermic energy is that exothermic energy is the reaction that releases energy and endothermic is the reaction in ehich energy is absorbed.
This is an endothermic process.
Endothermic reactions and exothermic reactions all involve something called an enthalpy change: a change in the amount of energy a chemical contains. The difference here is that exothermic reactions release heat energy to their surroundings, whereas endothermic reactions absorb heat from their surroundings (in effect, getting colder).
An endothermic reaction requires heat to form products. An exothermic reaction produces heat when it forms products.
Exo
The combustion is exothermic.
