Answer:

D: 142 °C

Explanation:

In pure substances, melting and boiling points are usually two distinct temperatures.

They are -12°C and 142°C.

We are told that at room temperature, thus substance becomes a soft grey solid. Thus, we can say that the temperature of the melting point is 142°C.

A continuous fractionating column is designed to separate a mixture of benzene
densk [106]

Answer:

in the fraction distillation method, two liquids such as benzene and toluene are produced from the mixture of benzene  and toluene.

Explanation:

Fractional distillation is a technique used in the industries for the separation of two or more liquids from one another. In this process liquid is heated, those liquid has lower boiling point will change into vapor form and collect in the upper chamber of fractional distillation while the liquid having higher boiling point also evaporates after sometime and keep it in another chamber. In the mixture of benzene  and toluene, the boiling point of benzene is lower so it evaporates earlier than toluene.

Difference between boiling point and freezing point​
Paladinen [302]

Answer:

<em>Lower vapor pressures of a substance has an obvious effect on a</em> <em>boiling point</em>. <em>The</em> <em>freezing point </em><em>the rate at which the solid melts is equal to the rate which freezes. </em>

Explanation:

<em>In practice, small differences between these quantities can be observed. It is difficult, if not impossible, to heat a solid above its melting point because the heat </em>
