Revinw I Constants I Periodic Table Matter can change from one physical state (phase) to another without any change in chemical identity. Each change is characterized by a specific name, a AH (enthalpy) value, and a AS (entropy) value The energy involved in phase changes and temperature changes can be calculated by using the following equations Part B Complete the sentences describing the steps needed to calculate the energy change associated with the conversion of 351 g of water ice at- 10 °C to steam at 125 "C.

Image: Graph, Energy on X axis, Temp on Y axis. There is a line sloping up and to the right labelled "A" beginning near bottom of Y-axis. At end of this line, there is a horizontal line labelled "B". At the end of this line there is another line sloping up and to the right labelled "C". End of Image. NH3 (MW = 17.034 g/mol) Melting point = minus 77.73 degrees C Boiling point = minus 33.34 degrees C Heat capacity of liquid = 4.700 J/g/K Heat capacity of gas = 2.060 J/g/K Heat of vaporization = 23.40 kJ/mol Find A, B and C (as far as 0 degrees C) and the total energy required (in that order) in Joules (express as 'J'). Assume 100.0 g of substance. A, B and C should have four significant figures. When entering your values import your answer followed by a space then J Example: 3450. J Notice that in this particular example a decimal point was included after 3450 to indicate that the zero is significant. If the answer does not need a decimal do not include one. 1.____ 2.____ 3.____ 4.____
