WebFeb 22, 2024 · Figure 16.4. 1: Solubility curves for several compounds. Notice how the temperature dependence of NaCl is fairly flat, meaning that an increase in temperature has relatively little effect on the solubility of NaCl. The curve for KNO 3, on the other hand, is very steep, and so an increase in temperature dramatically increases the solubility of ... WebIn the SI system, the specific heat is numerically equal to the amount of heat necessary to change the temperature of 1.00 kg of mass by 1.00°C. The SI unit for specific heat is J/(kg × K) or J/(kg × °C). (Recall that the temperature change ΔT is the same in units of kelvin and degrees Celsius.) sigfis tce https://pammcclurg.com
