Video transcript

Hello everyone today. We have the following question. A hypothetical substance has a normal melting point of 47 Kelvin give the temperature range when it is a liquid based on the given table. So something important to note is that the density of a substance will decrease significantly when we go from a solid to a liquid. And so the data shows that this density drop happened significantly Between 70° Kelvin and 80° Kelvin. So it is reasonable to assume that the boiling point is between this range, so 70-80° Kelvin is our range for our answer. And with that we've answered the question. I hope this helped, and until next time.
