• 1 States

At what temperature does water boils at atmospheric pressure?

• 101°C

• 98°C

• 100°C

• 101.2°C

At what temperature does water boils at 10 bar g?

• 184.13°C

• 194.14°C

As pressure increases, the specific volume of steam                 ?

• No change

• Increases

• Decreases

Total steam enthalpy (hg) = ?

• hf (enthalpy of water) + hfg (enthalpy of enthalpy)

• hf (enthalpy of water) + hfg (enthalpy of evaporation)

• hf (enthalpy of air) + hfg (enthalpy of evaporation)

• hf (enthalpy of gas) + hfg (enthalpy of evaporation)
