Answer:- C. decrease in temperature.
Explanations:- Solubility of a solid increases if the pressure is increased as the high pressure helps the solid to get dissolved in the solvent.
If the surface area of the solute is increased then more and more solute comes into the contact of the solvent and the solubility increases.
If the stirring is increased then it also helps the solute to get dissolved into the solvent.
Solubility of solids is directly proportional to the temperature.
So, if the temperature is decreased then solubility of the solute is also decreased.
In a combustion reaction, one of the reactants is always oxygen.
Answer:
Igneous rocks must go through the sedimentary process to change into metamorphic rocks. Igneous rocks are chemically changed into metamorphic rocks because of high temperature and pressure. Metamorphic rocks are formed from melting igneous rocks. Metamorphic rocks and igneous rocks do not follow a rock cycle.
