A simple example of an endothermic process is the melting of ice, because ice doesn't melt unless you put energy into it. This is also the case with other phase changes. If we want to boil water, we need to heat it up by pumping energy into it, and then once it boils we need to continue pumping energy into it until it has all turned to steam. However... Not all phase changes are endothermic.
