The amount of heat released is proportional to the amount of solute that exceeds its solubility.
WebThe minerals that make up igneous rocks crystallize at a range of different temperatures. This explains why a cooling magma can have some crystals within it and yet remain predominantly liquid. The sequence in which minerals crystallize from a magma is known as the Bowen reaction series (Figure 3.3.1 and Figure 3.3.3). WebHeat the flask gently on the steam bath for at least 10 minutes.
