Endothermic and exothermic reactions refer to the absorption or release of heat. Other types of energy may be produced or absorbed by a chemical reaction (examples include light and sound). In general, reactions involving energy may be classified asendergonic or exergonic, An endothermic reaction ...
An endothermic reaction takes place when energy is absorbed from surroundings in the form of heat, and exothermic is when energy is released from the system into the surroundings. Both terms are mostly used in science and chemistry, but there are everyday examples as well....
A good way to remember all of these is that opposite phase changes have opposite energy needs. If you know that from solid to liquid to gas requires the addition of heat (endothermic), that means you know that going from gas to liquid to solid requires the removal of heat (exothermic). ...

代入该方程式和恒定压力下内能的定义(ΔE=qp+w)到焓变方程中得出: 其中qp是在恒定压力下的反应热。 因此,如果化学或物理过程是在恒定压力下进行的,而唯一的功是由膨胀或收缩引起的(PV功),则热流(q < / em>p)和该过程的焓变(ΔH)相等。 运行本生灯时散发的热量等于发生的甲烷燃烧反应的焓变,因为它发生...
Endothermic and exothermic reactions Step 1: Energy must be SUPPLIED to break bonds: Step 2: Energy is RELEASED when new bonds are made: A reaction is EXOTHERMIC if more energy is RELEASED then SUPPLIED. If more energy is SUPPLIED then is RELEASED then the reaction is ENDOTHERMIC...
