Answer 1

Energy was released.

Answer 2

If an increase in temperature accompanies a reaction, it indicates that energy was absorbed.

Answer 3

If an increase in temperature accompanies a reaction, it generally indicates that energy was absorbed. This is because an increase in temperature means that the reactants gained energy from their surroundings. As a result, the reaction required energy input and is considered to be endothermic. Absorption of energy can cause the reactants to break their existing bonds and form new ones, leading to the formation of new products.
