Consider Figure 10.29. Can you label all of the red andblue lines in the graph with the mathematical expression that wouldbe used to calculate the amount of heat added? For example, the redline from 10 °C to 0 °C could be calculated by q = (m x cice x ΔT)or q = (mass x 2.09 J/g °C x 10 °C)
Temperature (°C) 100° 80° 60° 40° 20° 0° -10° H₂O(s) Liquid begins to boil H₂O(1) H₂O(g) and H₂O(1) Solid begins to melt H₂O(s) and H₂O(1) All solid melted H₂O(g) All liquid evaporated Amount of heat added FIGURE 10.29 A typical heating curve for a substance depicts changes in temperature that result as the substance absorbs increasing amounts of heat. Plateaus in the curve (regions of constant temperature) are exhibited when the substance undergoes phase transitions.
