What physical changes will occur to the steam within a boiler that has been properly bottled up when additional heat is applied?

🔍 Key Concepts

• Meaning of a bottled‑up boiler (all valves closed, no steam leaving, volume essentially fixed) • Definition of specific volume (volume per unit mass of steam) • How adding heat to a closed, rigid container affects pressure, temperature, and specific volume

💭 Think About

• If the boiler is properly bottled up, can any steam or water leave the system? What does that imply for total mass and total volume? • With total volume essentially fixed, think about what must happen to pressure when you add more heat to the same confined mass. • Specific volume is total volume divided by mass. If neither total volume nor total mass can change much, what does that suggest about specific volume as you heat the contents?

✅ Before You Answer

• Be clear on whether a properly bottled‑up boiler allows any flow in or out (mass change). • Decide whether the total volume of the steam space can significantly change as the boiler heats up. • Check your choice against the definition of specific volume = volume ÷ mass and see if both parts (pressure and specific volume) are consistent with a sealed, nearly rigid system.

Question 1 of 27070

What physical changes will occur to the steam within a boiler that has been properly bottled up when additional heat is applied?

The steam pressure and it specific volume will remain constant.

The pressure will increase and the volume will remain constant.

The pressure will remain constant and the specific volume will increase.

The pressure will increase and the specific volume will decrease.
