Look at the table of values of heat capacities of various substances. Compare the specific heat values of, for example, water and iron. Consider why the heat capacity of liquids is greater than the heat capacity of solids.
The specific heat capacity of water (4200 J / C * kg) is greater than the specific heat capacity of iron (460 J / C * kg) The heat capacity of liquids is greater than the heat capacity of solids, because molecules of liquids have more degrees of freedom than molecules of solids, and the distance between them is greater.
Remember: The process of learning a person lasts a lifetime. The value of the same knowledge for different people may be different, it is determined by their individual characteristics and needs. Therefore, knowledge is always needed at any age and position.
