The process is endothermic because the water is absorbing heat from the kettle. When energy (heat) is released as steam this is exothermic.
The formation of chloroform is an exothermic reaction, meaning it releases heat to the surroundings. This is because more energy is required to break the bonds in the reactants (methanol and bleach) than is released when forming the products (chloroform and water).
Exothermic because the heat of formation is -566. Exo- is negative and Endo- is positive.
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.
Endothermic. That is why it is used in ice packs.
The dissolution is endothermic.
When something burns it gives off heat. Therefore, it is exothermic.
Cloud formation is an endothermic process because water vapor molecules need to absorb heat energy from their surroundings in order to condense into liquid water droplets or ice crystals, releasing latent heat in the form of clouds.
Evaporation is an endothermic process.
The combustion of magnesium is an exothermic reaction because it releases heat energy. The bright white light and high temperatures produced in the reaction are characteristics of exothermic reactions.
Freezing is exothermic, as the substance that is freezing loses energy to its surroundings.
The process of clothes drying is not a chemical reaction, so it is neither endothermic nor exothermic. It is a physical process where water evaporates from the fabric due to heat energy, resulting in the drying of the clothes.
An endothermic compound absorbs heat or energy from its surroundings during a chemical reaction, causing a decrease in temperature. An exothermic compound releases heat or energy into its surroundings during a chemical reaction, causing an increase in temperature.
