sciences nerds i need you again

i mixed some substances in sciences lab and i need to find out if the reactions are exothermic or endothermic. if the temp went higher, is it exo or endo? (the citric acid and baking soda went lower and the sodium hydroxide and nitric acid went higher)

if temp increases it's exothermic, decrease is endothermic
