Welcome back everyone. We're told that the following images show the properties of a metal. Which of the following statements is correct. So looking at our first image, we have these metal rods that are packed very closely together, where we would recognize that from our Bunsen burner we have a very bright orange flame that is produced. And we would recognize that what this is signifying is that because of this close packing of these metal rods they are able to pass on vibrations to one another and very well conduct the heat of this flame here. So we would confirm that this image A. Is describing metals as good conductors of heat, whereas an image be we have a very hot, molten looking structure that is melting into this liquid here. And we would understand that this is describing the properties of metals which have very high melting points due to their giant lattice structures and due to their giant crystal lattice structures, we would recognize that this means that there is a large amount of electrostatic force that must be broken to melt or to allow these metals to melt. So ultimately in summary image B describes metal high melting point metals high melting point. So looking at our options below, we have statement A which reads that image A shows that metals have high melting points. So let's already roll choice A out. We agreed that its image be that describes the high melting points of metals. So, Image A. And statement B shows that metals are good conductors of heat. While image B shows that metals have high melting points. we can so far agree with statement. Be moving onto statement see Image A. Shows that metals are good conductors of electricity. While Image B shows that metals have high boiling points, we would rule out Choice C. It's not describing the boiling point is describing the melting point, which is why we see our metal being turned into this molten liquid here and now. We have a statement D. Image A shows that the metals are good conductors of heat. While Image B shows that metals are good conductors of electricity, we would completely rule out Choice D. Meaning that the only correct choice to complete this example as the true statement with regards to our images A. And B. Is going to be Choice B. So I hope that everything I explained was clear. If you have any questions, please leave them down below. Our final answer is B. Image A shows that metals are good conductors of heat. While Image B shows that metals have high melting points, I'll see everyone in the next practice video
