Question

Sapling Learning macmm leaming The speciic heat of water (4.180 J (g K)-1) is greater than that of many other substances, such as aluminum, copper, and iron, which have specific heats of 0.902 J (g-K)-1, 0.395 J (g-K)-1 and 0.449 J (g K)-1, respectively. Based on this piece of information, which of the following statenents about water can you assume to be true? oEarth's temperature variations are moderate because of the significant amount of O O O water on its surface. Water is known as the universal solvent. It enables organisms in aquatic system to survive winter. Droplets of water in the liquid state form clouds. It is very hard to remove some pollutants from water.

Explanation / Answer

The specific heat of water is more as comparision to copper ,iron and aluminium.It means that there will be large energy requirement to rise the temperature of water by one degree celsius.

So , option A is correct .

Earth's temperature varitions are moderate because of significant amount of water on its surface.
