"hot liquid" and "liquid so hot that it will burn my skin" are not necessarily the same thing. Unless you think that people should feel afraid of a hot bath or a hottub (or even going to a hot spring).

In more precise terms, 'boiling' is a subset of 'hot.'

Wow, you all are really discussing this? If "hot" may mean "hot" or just "hot" and if the fact that hot coffee is hot is common knowledge?

Thanks, now I understand why it is so important to write obvious things on products in the USA. Maybe it actually is necessary...
