3 C6H12O6,
C=3*6=18 Carbon atoms
H=3*12=36 Hydrogen atoms
O=6*3=18 Oxygen atoms
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.
