- 7. 3: Exothermic and Endothermic Reactions - Chemistry LibreTexts
In the course of an endothermic process, the system gains heat from the surroundings and so the temperature of the surroundings decreases (gets cold) A chemical reaction is exothermic if heat is released by the system into the surroundings
- Endothermic and exothermic processes - Khan Academy
At constant pressure, q is equal to the change in enthalpy (ΔH) for a process If ΔH is positive, the process absorbs heat from the surroundings and is said to be endothermic If ΔH is negative, the process releases heat to the surroundings and is said to be exothermic

One statement of the first law of thermodynamics is that the amount of work done on a system is dependent of the pathway the total work done on a system must equal the heat absorbed by the system the total work done on a system is equal in magnitude, but opposite in sign of the heat absorbed by the system the total energy change for a system
- Endothermic and Exothermic Processes - AP Chemistry Guide
ΔH solution refers to the heat absorbed or released when a given amount of a solute dissolves in a given amount of solution When heat is absorbed for a dissolution process, ΔH solution is positive and the process is said to be endothermic When heat is released, then ΔH solution is negative and the process is said to be exothermic
- AP Chemistry 6. 1 Endothermic and Exothermic Processes Study Notes
– Endothermic: Melting, evaporation (heat is absorbed) – Exothermic: Freezing, condensation (heat is released) 2 Phase Changes: i Melting (Melting or Fusion): – Energy absorbed: It takes heat to break bonds among particles of a solid and melt it to turn into liquid – Illustration: Melt water from ice ii Freezing (Solidification):
- Understanding Endothermic and Exothermic Reactions
In short: Endothermic reaction: Absorbs heat (feels cold) Exothermic reaction: Releases heat (feels hot) These energy exchanges are part of a broader field known as thermochemistry, which studies the heat involved in chemical and physical processes Let’s dive deeper into each type
- Endothermic and exothermic processes | EBSCO
Endothermic and exothermic processes are two types of heat-related changes that matter undergoes, affecting its physical or chemical properties An endothermic process absorbs thermal energy from the environment, resulting in changes such as melting, evaporation, and sublimation
