The two effects do impurities have on the melting point of an organic compound are given as ,
- They tend to lower the overall melting point of the compound versus the value for he pure material .
- They ends to increase the range of the melting point values .
The impurities decreases the melting point of the substance of organic compounds . This is because there are unwanted particles which weaken the lattice structure of the solids crystal due to which it become less stable and melts before its original melting point.
Example : Let take a clay and add dirt hen it breaks easily from the points where there is dirt . This is essentially what happens with impurities

The answer is that exact locations within either cannot be determined at any given moment in time.
An electron cloud be compared with a spinning airplane propeller in the manner that in both exact location within either cannot be determined at any given moment in time.
In both electron cloud as well as spinning airplane propeller, there is a probability of finding either but exact location can not be determined.
From the above statement, John can infer that the rock underwent metamorphism and also is not altered by heat or pressure.
<u>Explanation</u>:
- Metamorphic rock is an igneous sedimentary rock and although when put through heat the rock becomes hot but does not alter its shape or melt. If the rock melts then it is only an igneous rock and not a sedimentary one.
- During metamorphism, the chemical and the mineral content of prolith are changed due to changes in the environment based on physical and chemical conditions.
- Even though the rocks remain solid, fluid is present between the macroscopic spaces.
- This gives "The Geologist" accurate information of what happens beneath the earth during the formation of mountains.
- Metamorphic rocks are like probes that go down the earth and comes back giving information of what happens underneath the surface.
There are 2 types of electricity, static electricity and current electricity
