Questions & Step-by-Step Solutions
Which of the following has the highest entropy at 298 K?
Step 1: Understand what entropy means. Entropy is a measure of disorder or randomness in a system.
Step 2: Know the states of matter: solids, liquids, and gases. Gases have more disorder than liquids, and liquids have more disorder than solids.
Step 3: Compare the substances given in the question. Identify if they are solids, liquids, or gases.
Step 4: Recognize that at 298 K (25 degrees Celsius), water can exist as a solid (ice), liquid (water), or gas (water vapor).
Step 5: Determine which state has the highest entropy. Since gases have the most disorder, water vapor will have the highest entropy compared to liquid water and ice.
