Question

At three different temperatures, T1, T2, and T3, the molecules in a liquid crystal align in these ways:

(b) Which is the highest of these three temperatures? [Section 11.7]

Accepted Answer

Step 1: Understand the properties of liquid crystals. Liquid crystals are a state of matter that has properties between those of conventional liquids and those of solid crystals. For instance, a liquid crystal may flow like a liquid, but its molecules may be oriented in a crystal-like way.. Step 2: Know the different phases of liquid crystals. There are several different phases of liquid crystals, but the most common are the nematic, smectic, and cholesteric phases. In the nematic phase, the molecules are aligned along one direction, but not layered. In the smectic phase, the molecules are aligned along one direction and also layered. In the cholesteric phase, the molecules are aligned along one direction and layered, but also twisted.. Step 3: Identify the phase of the liquid crystal at each temperature. From the description given in the problem, identify which phase the liquid crystal is in at each temperature T1, T2, and T3.. Step 4: Understand the relationship between temperature and phase. As the temperature increases, the order of the liquid crystal decreases. This means that the liquid crystal goes from a more ordered phase (like smectic or cholesteric) to a less ordered phase (like nematic).. Step 5: Determine the highest temperature. Based on the phase of the liquid crystal at each temperature, determine which temperature is the highest. The highest temperature will be the one at which the liquid crystal is in the least ordered phase.
