Extracted text: 1. What is the state of H2O if P = 725 kPa and T= 151 °C? 2. What is the quality or degrees of superheat of H2O if P = 400 kPa and V= 607.2 cm/g? 3. What is the temperature of H2O if P = 1000 kPa and U = 2810 kJ/kg? 4. What is the temperature of H2O if P = 150 kPa and H= 1814.3 kJ/kg? What is the specific volume? What is the specific internal energy? What is the specific entropy? What is the quality of degrees of superheat (whichever is applicable)? 5.Calculate the change in enthalpy of 500 kg of CaCO3 when it is heated at atmospheric pressure from 50 °C to 880 °C. 6. Twenty kg of wet steam is initially at 1 bar with a quality of 98%. Through a series of processes, it is converted to steam at 100 bars and 500 °C. Calculate the change in enthalpy. 7. Consider heating 2 moles of steam from 1000 kPa and 200 °C to 500 °C at constant pressure. Calculate the associated change in enthalpy using the following sources for data: a) Heat capacity b) Steam Tables
