Final answer:
No, the sand being more dense than water is not a chemical property. Density is a physical property that can be measured without altering the substance's chemical identity. This concept is related to the comparative specific heat of sand and water and how they absorb and release heat.
Step-by-step explanation:
The question of whether the sand being more dense than water is a chemical property can be answered by understanding what constitutes chemical and physical properties. Density is an example of a physical property because it can be measured and observed without changing the substance's chemical identity. Chemical properties, on the other hand, describe a substance's ability to undergo a specific chemical change. An example is flammability, which is a chemical property.
Sand being more dense than water does not involve a chemical reaction or change in its chemical structure; it is simply a measurement of mass per volume. The density of a substance, including sand and water, can be affected by temperature since most materials expand as temperature increases, causing the density to decrease. This directly relates to the exercise where the specific heat of water is compared to that of land, exploring how different materials absorb and release heat.
Conclusively, the correct answer is No, the sand being more dense than water is not a chemical property; it is a physical property.
