Molecules in the solid phase have the least amount of energy, while gas particles have the greatest amount of energy.There are space between particles of matter. The average amount of empty space between molecule gets progressively larger as a sample of matter moves from the solid to the liquid and gas phases.
The molecules in the sugar move from an area of higher concentration (sugar cube) to an area of lower concentration in the water.
That is exactly what diffusion is: the net movement of molecules or atoms driven by a gradient , which means that it doesn’t requires energy.
Correct answer: Magnetic field is created when molten material is heated from earth's core.
Due to the movement of molten iron and nickel inside the core of the earth magnetic field is generated. Due the the generation of high temperature all the molten material are in the liquid form. A Coriolis force is generated due to flow of molten liquid, which result in the formation of magnetic field.
The magnetic field of the earth is used to protect the earth from the harmful solar radiation .
So other scientists can try the exact same experiment and see if they both got the same results.
