∆ Conductors are materials that can carry electricity - they conduct electricity.
∆ Metal materials such as copper, iron, steel and aluminium are all good conductors of electricity.
∆ Convection: The process of heat transfer from one part of a fluid to another part by the actual movement of the particles of the fluid is called convection.
∆ Land breeze - A local wind system characterized by a flow from land to water late at night. Land breezes alternate with sea breezes along coastlines adjacent to large bodies of water. Both are induced by differences that occur between the heating or cooling of the water surface and the adjacent land surface.
∆ Sea breeze - It describes a wind that blows from the ocean inland towards land. This breeze occurs most often in the spring and summer months because of the greater temperature differences between the ocean and nearby land, particularly in the afternoon when the land is at maximum heating from the sun.
