Imagine you are conducting two chemical experiments in your science class. In both experiments, you mix two substances together and observe the reactions. Your task is to identify whether each reaction is endothermic or exothermic based on the provided observations.
Experiment 1: You mix two colorless liquids together, and as the reaction occurs, you notice that the container feels cooler to the touch than it did before the reaction began.
Experiment 2: You mix two colorless liquids together, and as the reaction occurs, you observe that the container becomes warm to the touch, and you can see steam rising from the reaction mixture.
Based on your observation, which experiment is endothermic?
A. Experiment 1
B. Experiment 2
