Question 229Steam Plants - 1st Asst/Chief70% to pass
What physical changes will occur to the steam within a boiler that has been properly bottled up when additional heat is applied?
AI Explanation
The correct answer is C) The pressure will increase and the specific volume will decrease.
When a boiler is properly bottled up, the steam inside is a closed system. According to the laws of thermodynamics, when additional heat is applied to a closed system, the pressure will increase while the specific volume (volume per unit mass) of the steam will decrease. This is because the mass of the steam remains constant, but the energy input causes the steam to become more compressed.
The other options are incorrect because they do not accurately describe the changes that occur to the steam under these conditions. Option A is incorrect because the volume would decrease, not remain constant. Option B is incorrect because both the pressure and specific volume would change. Option D is incorrect because the pressure would increase, not remain constant.
