Heating almost to boiling means that the liquid doesn't boil. Heating just to boiling means the liquid boils.
The difference between them is that boiling is when you heat a liguid and it turns into a gas, vaporization is when a liquid changes into a gas and evaporation occurs at the surface of a liquid beneath its boiling point.
Boiling is a greatly expedited form of evaporation. When you heat something to its boiling point, it has enough energy for its molecules to rapidly escape. Evaporation is a much slower action, generally. It is just molecules at the surface gaining enough energy to escape. Both evaporation and boiling are endothermic processes. They will cool what ever the molecules are escaping from.
Evaporation occurs only at the surface. Boiling happens anywhere in the liquid.
The main reason is that Mercury has almost no atmosphere which would hold the heat in. So the temperature on the side which is facing away from the Sun can plummet.
Under ordinary conditions they are the same 'point'. For example, water just freezes and it just melts at zero degrees centigrade. The difference between the two states is not temperature, but the heat of fusion. When the heat of fusion is removed from water at zero degrees, it will freeze. When the heat of fusion is added to ice at zero degrees, it will melt.

Boiling : the temperature increases substance changes its form from liquid to gas atoms of the substance moves with the high kinetic energy by absorbing heat Condensing : the temperature decreases substance changes its form from gas to liquid atoms of the substance loses atomic kinetic energy by losing heat
A burn is caused by dry heat whereas a scald is caused by wet heat. A burn can be caused by heat or cold, and this can be wet or dry. A scald is a burn caused by wet heat such as boiling water.

what is the difference between product analysis and heat analysis
Boiling tubes are used to heat substances to extreme temperatures. Boiling tubes are almost twice the size of regular test tubes. They are designed to allow substances to violently boil without boiling over or exploding out.

actually there is no difference , infact condenser itself is a heat exchanger
