please show the answer in steps.
1)What is the change in entropy when a) 100 g of ice is meltedat 0 ℃ b) 100 g of water is vaporized to 100 ℃
Use the values for each step to calculate the change in entropywhen 100 g of ice at 0 ℃ is transformed to water vapor at 100 at ℃. Suppose that the changes are brought about by a heater thatsupplies at a constant rate and sketch a graph showing a) thechange in temperature of the system b) the enthalpy of the system,c) the entropy of the system as a function of time.
2)The average of the enthalpy of vaporization of propanone,C3H6O over the temperature range of 280 to340 K is 30.2 kJ/mol. The vapor pressure is 30.600 kPa at 298.15 K.Estimate the normal boiling temperature of propanone.
