You should talk about how it evaporates then it turn into a gas then back in to a liquid
Magnetic separation is a method that uses magnetic force to remove the magnetically sensitive material from a mixture. Because iron is attracted by magnets, this is the ideal method for separating sand and iron fillings.
Magnetism was the physical attribute that allowed this combination to be separated. I used the magnet to separate the iron filing from the sand in the mixture. The magnet attracted the iron filings but not the sand. We were able to separate the iron filings from the sand as a result of this.
Because iron is magnetic while the other two are not, a magnet may be used to pull the iron filings out of the mixture while leaving the salt and sand. Sand is not water-soluble, although salt is. This implies they may be combined in water and swirled together. The salt dissolves, but the sand does not.

"20 J" is the "Potential Energy" of "vase" on the table.
<u>Explanation</u>:
The body possess some energy according to the position of the object that is the when an object is placed at a height it stores some energy it is called "Potential Energy".
Formula used to calculate the "Potential Energy" is 
Where, "m" is mass of vase is given that 2 kg, "g" is acceleration due to gravity is 
and "h" is height of the object where it placed is 1 m.
Substitute the given values in the formula,
Potential energy of the vase = 
Potential energy of the vase = 20 J
Answer:
Scientific reasoning (SR), broadly defined, includes the thinking skills involved in inquiry, experimentation, evidence evaluation, inference and argumentation that are done in the service of conceptual change or scientific understanding.
The answer is c, bc we are talking about a solid and adding more energy to a solid makes it melt.
