  Re: what is the difference between melting range & melting point? Which is more significant?
Answer
# 1
melting range means range of temperature at which
temperature sample startsmelting(solidform to liquid form)
and at which temperature completely converted to liquid
form.example 121.4-123.6


melting point means sample melts sharply one point of
tmperature , example 82

Answer
# 4
m range: solid starts melt to complete liquid temperature 123..124..125..126..127..128



m point: average value of m range temperature 125.5 .... why because we didn't find out exact melting point through melting point apparatus.
