solid) coexist, and the critical point is the point on a phase diagram at which the substance is indistinguishable between liquid and gaseous states. Activity 1: Specific Heat Capacity Open the Energy Forms and Changes simulation. Choose the Intro tab. Play around to become comfortable with the sim. 1. Attach the temperature gauge to each object (brick, iron, and water) so you have a temperature guide. Which object (brick, iron, and water) is at the higher temperature? 2. Which object (brick, iron, and water) contains more energy? To answer this question make sure the energy symbols box is checked 3. Reset the sim. Place the water beaker on the stand. Chill the water as much as possible, then add heat and observe. List below at least three observations (make sure the energy symbols box is checked.) 4. Reset the sim. Heat the iron block to the maximum temperature. Place the heated-up iron block in the water container at room temperature. Describe what happens with the temperature and energy stored by each object. 5. Reset the sim. Cool the iron block to the minimum temperature. Place the cooled-down iron block in the water container at room temperature. Describe what happens with the temperature and energy stored by each object
