The heat energy associated with a change in temperature that does not involve a change in phase is given by -msAT where q is heat in joules, mis mass in grams, s is specific heat in joules per gram-degree Celsius, J/(g·°C). and AT is the temperature change in degrees Celsius. The heat energy associated with a change in phase at constant temperature is given by where q is heat in joules, m is mass in grams, and ? H...

1.If 245 Joules is required to change the temperature of 14.4 g of Chromium by 38.0 K, What is the specific heat of capacity of Chromium? 2. Calculate the energy in the form of heat (in kJ) required to convert 225 grams of liquid water at 21.0 °C to steam at 115 °C. (Heat of fusion = 333 J/g; heat of vaporization = 2256 J/g; specific heat capacities: liquid water = 4.184 J/g·K, steam = 1.92 J/g·K)

B. Calculation of Heat during phase change. A phase change is a physical process in which a substance goes from one phase to another. The temperature of a substance does not change as the substance goes from one phase to another. The heat of fusion (AHfus) is the amount of heat per gram (or per mole) required for a phase change that occurs at the melting point. The heat of vaporization, (Hvap) is the amount of heat per gram (or...
