The material’s temperature decreased 80 degrees celcius
A graph enables you to easily denote the relationship between variables as positive or negative.
<h3>What is a graph?</h3>
This question is incomplete but I will try to help you as much as I can. A graph is one of the numerous was of data representation in science. A graph has two axes; the vertical ( Y - axis) and the horizontal (X - axis).
A graph enables you to easily denote the relationship between variables as positive or negative. A graph is sometimes called a scatter plot.

Answer:
the asymmetrical arrangement of hydrogen atoms in a molecule of water causes the molecule to be polar, with the hydrogen atoms having a slightly positive charge, and the oxygen atom having a slightly negative charge.
Answer: Option (c) is the correct answer.
Explanation:
As we know that density the amount of mass present in per unit volume.
Mathematically, Density = 
So, it means that density is inversely proportional to volume. Hence, when there will be decrease in density of a substance then there will be increase in its volume. That is, expansion of substance will take place.
Also, boiling point of copper is 2,562 degree celsius but we are heating it up to a temperature of 95 degree celsius. This means that copper will remain in liquid state at this temperature.
Thus, we can conclude that a change which occurs in a sample of copper is that copper sample will expand.
