Q3.4 Reflecting on Differences in Phases Think about what you already know about different phases of matter. Given this figure showing the process of changing from one phase to another, what parameter (physical quantity of a system) serves as an indicator for energy flowing into or out of the molecular system? Gas Cool or compress Heat or reduce pressure Liquid Cool Heat Crystalline solid In the box below, make a claim as to which parameter is represented in the processes in the figure and use your ideas of energy to support your claim.
Scenario #1- You are cooking when you burn your hand. Which would hurt more: burning your hand with 50 g of boiling water or burning your hand with 50 g of steam? Keep in mind that when burning your hand in water, the water hits your skin, and the water temperature changes from 100°C to 37°C. When burning your hand with steam, the water hits your skin, condenses, and then the water temperature changes from 100°C to 37°C. A. Determine the classification of the substances in your scenario B. Determine if characteristics described are chemical or physical. C. Give the calculations (and calculation type) used to answer the question in the scenario. Show your work.
