Hello Everyone in this video we're trying to do is compare this graph to the statement and seeing if this is true or false. The statement reads the behavior of a superconductor, a material that total loses all electrical resistance below below its superconductor transition temperature is shown in the graph below. And the graph they're referring to is of course this one over here. So we're talking about the behavior of a superconductor. What we're talking about is choreographing it senses before the critical temperature, assuring it to temp here. The resistance of the superconductor is zero. And then so there's just talking about the before and after the cold temperature, the resistance of the superconductor increases as the temperature increases. So you see from the graph here that's provided the axis is the X axis is a temperature and then which is making this independent and are dependent. Ry is going to be the electrical resistance servicing here for the behavior of a superconductor. Before the critical temperature the resistance of the superconductor zero. So we should see sort of a flat line. So let's draw what we should see. And seeing if this matches. So if it's zero it means that this is basically a flat line like so and then once we hit the critical temperature, let's say this one right here is critical temperature I just put T. C. It should rise. It should increase as our temperature increases as well. So both increases. So something linear like this. This is what we should be seeing. However here we see that none of this is equal to zero in regards to our resistance, so therefore our statement here is false. So then this right here, this false answer that we just highlighted that's going to be my final answer regarding this problem.
