There are two possible reasons why these questions have been asked:
1 To realise that the terms 'hot' and 'cold' have no absolute meanings and are simply relative to some other reference temperature (often human body temperature of 37�C).
2 To get the pupil to do some research (or actually measure a temperature)
To give you an idea of what these temperatures are likely to be:
Hot bath water is just above body temperature 40�C - 42�C
The North Pole is around 0�C in summer and -35�C in winter
