What changes igneous or sedimentary rock into metamorphic rock?
Answers
Answer:
The answer is Temperature (Heat), Pressure and chemical activity of fluids.
Explanation:
Metamorphic rocks result from the transformation of pre-existing rocks that have undergone structural and mineralogical changes under certain physical or chemical conditions such as temperature, pressure or chemical activity of the fluids. This type of modification is known as a process called metamorphism, in which igneous rocks or sedimentary rocks, when subjected to high temperatures, pressures or active fluids, cause changes in their composition, bringing new substances to them.

Explanation:
Homogeneous mixture is separated using two stage separation process: mobile stage and stationary stage. The mobile phase are absorbent such as water, chemicals while the stationary stage is the column used for the separation process. The integral method of separation of homogeneous mixtures is called chromatography (analytical or preparative). Other method of separation of homogeneous mixtures is called distillation and it is based on the various boiling points of the component of mixture.
While heterogeneous mixtures are separated based the properties of the components. One method of separation of solids suspended in liquids is simple filtration.

1. A pH meter, 2. Litmus paper/ pH test strips or 3. Titrations.
1. A pH meter works by sending a small electric current through the solution. An electrical current can only be created if there are free-moving particles such as H+ ions from an acid or OH- ions from a base. The pH meter can determine the pH by how high the conductivity is.
2. Litmus Paper or pH test strips are strips that turn a specific colour under a specific pH. This colour can then be compared to a colour chart which will tell you the pH. The downfall of this method is that the red ink will stain the strip and you will be unable to get an accurate reading.
3. A titration is the best method, if done properly, for determining pH.
