1. The branch of chemistry that studies the relationship between chemical reactions and heat energy changes
Thermochemistry helps us understand how much energy is released or absorbed during combustion reactions.
A termoquímica nos ajuda a compreender quanta energia é liberada ou absorvida durante reações de combustão.
2. The study of heat changes associated with chemical processes, including enthalpy and entropy
In thermochemistry, we measure the enthalpy change to determine if a reaction is exothermic or endothermic.
Em termoquímica, medimos a mudança de entalpia para determinar se uma reação é exotérmica ou endotérmica.
Thermochemistry is a fundamental subject in chemistry curricula worldwide. In Brazil, it is typically taught in high school (Ensino Médio) chemistry courses and extensively in university chemistry programs. The term is standardized across both Brazilian and European Portuguese scientific communities and is commonly used in academic publications, textbooks, and laboratory settings.
