A reaction releases heat energy to the surroundings, causing the temperature of the surroundings to rise. This type of reaction is called:
Correct: B
Exothermic reactions are chemical reactions that release energy, typically in the form of heat or light, into the surroundings. This release of energy leads to an increase in the temperature of the surroundings. Endothermic reactions, conversely, absorb heat from the surroundings, causing the surroundings' temperature to decrease.
