ACTIVITY/EXERCISES Direction: Graph the heating curve of ethanol using the information given. Check off each item as you add additional information to your graph so that none is missed. Background information of Ethanol: Boiling Point - 78 °C Melting Point =-114 °C Starting Temperature -120 °C %3D 1. After two minutes, frozen cold ethanol starts to melt. It takes two minutes to melt completely. 2. After eight more minutes, it begins to boil. It boils for six minutes. 3. Heat is added for two more minutes until ethanol reaches 80 °C. 4. Label "melting" where this takes place. 5. Label "vaporization" where this takes place. 6. Label "phase change" where a phase change occurs. 7. Indicate where ethanol is only a SOLID, only a LIQUID, and only a GAS. 8. Of the three phases, label which phase has: weakest IMF, strongest IMF, and medium IMF.

3 example problems with solution about TEMPERATURE AND HEAT.
Use the heating-cooling curve below to answer the following questions. 160 Temperature (°C) 140 A curve with five distinct linear sections is shown on a plane with a horizontal axis labeled: "Heat added at a constant rate" with a right arrow suggesting the heat added increases from left to right. The vertical axis is labeled: "Temperature (°C)". • First section: starts at origin with an approximate 80 temperature of 0°C, moves up and to the right, and ends at approximately 19°C. . Second section: continues right horizontally. • Third section: moves up and to the right, ending at 40 approximately 102°C. • Fourth section: continues right horizontally. The horizontal 20 distance for this section is much greater than the other sections. • Fifth section: moves up and to the the graph at approximately 160°C. e right, exiting the top of (a) What is the freezing point (in °C) of the liquid? °℃ (b) What is the boiling point (in °C) of the liquid? °℃
