°Thought just occurred to me.. Is there a standard way of referring to temperature either of a phase change?
For example if I write..
"1kg of water is cooled from 20°C to 0°C, how much energy was removed?"
...then potentially two answers might be considered correct depending if you include the latent heat or not. In many cases it's obvious because a problem statement might say.. .
"water at 0C is heated...
or
"Ice at 0C is heated...
and "water" or "ice" implies which side of the phase change you are starting from but is there a standard or shorthand way to write (for example) "0°C" that differentiates between one side of the phase change vs the other?
