The presence of crystals can affect the heat measurement of molten salt. Also, the molten salt must be super-cooled for constant pressure.
We can arrive at this answer because:
- A calorimeter is an instrument used to assess the amount of heat emitted in an element or solution.
- In this case, to know the amount of heat, that is, thermal energy emitted, in a substance, the substance must be as pure as possible.
- This is because substances that contain mixtures can affect the measurement made by the calorimeter, as they will present different thermal emissions.
Furthermore, when in contact with water, the salt can cause pressure changes, which can impair the measurement of the calorimeter in relation to the salt. To prevent this from happening the salt must be super-frozen, thus maintaining a constant temperature.
