During an experiment water was heated in a container covered with a glass lid. The following observations were recorded. Observation 1: Water droplets form on the inside of the glass lid.
Observation 2: Bubbles rise as the water starts boiling.

Based on the observation, justify the type of change (physical or chemical) that took place.

To find the enthalpy of a reaction in the lab, you measured the of the reactants and the change during the reaction.
