Question 1 Of the following which displays a positive energetic process?
1 answer:
We can describe a positive energetic process as any process which increases the internal energy of the system.
A positive energetic reaction or process is often referred to as being Endothermic. This means that the system which is performing the process absorbs energy. Some examples include:
- Boiling an Egg
- Roasting food over a fire (the food is the reference system)
etc
Therefore, we can confirm that a positive energetic process is one in which the system in question absorbs energy, thus increasing its internal energy.

Answer: 0.100 m
Explanation:
Elevation in boiling point is given by:
= Elevation in boiling point
i= vant hoff factor
= boiling point constant
m= molality
1. For 0.100 m
, i= 3 as it is a electrolyte and dissociate to give 3 ions. and concentration of ions will be
2. For 0.100 m
, i= 2 as it is a electrolyte and dissociate to give 2 ions, concentration of ions will be
3. For 0.200 m
, i= 1 as it is a non electrolyte and does not dissociate, concentration of ions will be
4. For 0.060 m
, i= 4 as it is a electrolyte and dissociate to give 4 ions. and concentration of ions will be
Thus as concentration of solute is highest for , the elevation in boiling point is highest and thus has the highest boiling point.
