An endothermic process is a chemical reaction or physical change that absorbs heat from its surroundings, causing a decrease in temperature. An exothermic process, on the other hand, is a chemical reaction or physical change that releases heat into its surroundings, causing an increase in temperature.
One way to determine whether a process is endothermic or exothermic is by measuring the temperature change of the system. If the temperature of the system decreases during the process, it is likely an endothermic reaction or change. Conversely, if the temperature of the system increases during the process, it is likely an exothermic reaction or change.
For example, the process of melting ice is endothermic because it requires heat to be absorbed by the ice to break the intermolecular bonds and change the solid into a liquid. We can determine that this process is endothermic by measuring the temperature of the ice as it melts. As heat is absorbed by the ice, the temperature of the ice will decrease until all of the ice has melted.
