They are characterized by a regular crystalline organization of atoms that confer a long-range order. Amorphous, or non-crystalline, solids lack this long-range order. Accordingly, they lack the elasticity, distinct melting points, and other properties of crystalline solids
You need to convert minutes to hours so
I think the correct answer would be the first option. The process that would explain this phenomenon is convection. It is a mode of heat transfer which is a result of bulk movement of a substance due to the difference in density which is a result of the temperature of these substances. This transfer of heat is applicable to fluids. When the temperature of a fluid increases, the fluid expand thus decreasing its density. However, for a fluid which has a cooler temperature, it would contract resulting to a much higher density. Therefore, the warm fluid would rise up while the cooler fluid would sink below the warm fluid.
Scientific Method: Because, they use their method which the scientific one to solve investigations.
