So, finally, $$\Delta H=Q$$ So, for a process carried out at constant pressure, if the heat added to the system is positive (endothermic), $\Delta H$ is positive and if the heat added to the system is negative (exothermic, heat removed from system), $\Delta H$ is negative. Mesomorphy basically serves as a diluted measure of muscle mass, which is correlated with absolute strength. This is a tricky one. Find out more. Each square carries a letter. exo- and endo- refers to the ability of a glycoside hydrolase to cleave a substrate at the end (most frequently, but not always the non-reducing end) or within the middle of a chain .
