During an exothermic reaction.
Endothermic reactions are those which absorb energy in the form of heat from the surroundings. This results in a decrease in the temperature of the surroundings during the reaction.
Endothermic changes are processes where energy is absorbed by the system from its surroundings. This results in a decrease in temperature in the surroundings during the process. Examples include melting ice and evaporating water.
Cooling occurs during evaporation because the process requires energy to convert liquid water into water vapor. This energy is taken from the surrounding environment, leading to a decrease in temperature.
During an endothermic reaction, energy is absorbed from the surroundings. This energy is often taken from the immediate environment, including your skin, resulting in a cooling sensation. Even though energy is being absorbed overall, it feels like heat is being taken away from your body, making it feel cold.
You probably mean "what reaction releases energy," in which case, lots. Reactions that release energy into the environment are called exothermic reactions. An example of which would be mixing sodium (Na) and water (H2O) to form sodium hydroxide (NaOH), hydride (H2), and heat/energy. 2Na + 2H2O ---> 2NaOH + H2 + heat/energy
no, endothermic trust me it shows it in my book
The main form of energy taken by the leaf during photosynthesis is light energy from the sun. This energy is captured by pigments in the chloroplasts of the leaf, such as chlorophyll, and converted into chemical energy in the form of glucose.
Water is taken in. Light energy is used
no, endothermic trust me it shows it in my book
No, energy cannot be taken during a physical change. Energy is always conserved, meaning it cannot be created or destroyed, only transferred or transformed from one form to another. During physical changes, such as melting or boiling, energy is absorbed or released, but the total amount of energy in the system remains the same.
Depending on the particular chemical reaction, energy may be either released or absorbed.

What happens when thermal energy is taken away
About 10% of the total energy taken in by an herbivore is stored in its tissues. The rest of the energy is used for growth and development, metabolism, reproduction, and some is given off as heat.
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.
Producers use about 90 percent of the food energy they make during photosynthesis for their life processes.
