Flat portion heating curve
Webin this new video, we're gonna take a look at heating and cooling curves. So we're gonna say here in heating and cooling curves we have the representation of the amount of heat, absorb or release during phase changes. Now, let's pretend that this heating curve represents that of water and we call it a heating curve because you can see that over ...
