Video transcript

Hey everyone where asked which of the following statements is true. Looking at our answer choices, it looks like we're talking about ice, a tropic liquids, its viscosity and how it compares to our liquid crystalline phase. First let's think about what we've learned. We know that in our liquid crystalline phase our molecules are not totally free to change in orientation and order is maintained in at least one dimension. So this would make our liquid crystalline phase more resistant to flow, which means it would be more fiscus in comparison to our ice. A tropic liquid. Looking at her answer choices, it looks like a is going to be your answer because we stated that our isotopic liquid will be less viscous than our liquid crystalline phase. And that is because our molecules are not free to change in orientation in our liquid crystalline phase. And we also mentioned that at least one dimension is kept in order. So I hope this made sense. And let us know if you have any questions

At 25 °C gallium is a solid with a density of 5.91 g/cm3. Its melting point, 29.8 °C, is low enough that you can melt it by holding it in your hand. The density of liquid gallium just above the melting point is 6.1 g/cm3. Based on this information, what unusual feature would you expect to find in the phase diagram of gallium?
