WebPlot a graph of temperature against the volume of acid added, and use extrapolation of the two sections of the graph to deduce the maximum temperature reached without heat loss. Use your results to calculate the concentration of the hydrochloric acid. Teaching notes. The main concern in this experiment is the heat loss. 馬尿酸 下げるにはWebA phase diagram indicating the temperature changes of water as energy is added is shown in Figure 11.10. The ice starts out at −20 °C, and its temperature rises linearly, absorbing heat at a constant rate until it reaches 0 °. Once at this temperature, the ice gradually melts, absorbing 334 kJ/kg. tarjeta cuidar tu salud nlWebThe enthalpy-temperature curve PQ for saturated air is plotted either using calculated data or from the humidity chart (Figure 13.4).
