Explanation:
A freezing point is defined as the point in which a liquid state of a substance changes into solid state.
Whereas boiling point is defined as the point at which liquid state of substance starts to convert into vapor state.
So, a substance is freezing at [tex]10^{o}C[/tex] and boils at [tex]70^{o}C[/tex] then it means at room temperature, that is, around [tex]25^{o}C[/tex] the substance is present in liquid state.
This is because between the freezing and boiling point a substance will always exist in liquid state.
Thus, we can conclude that state of the material at room temperature is liquid.
