🔍 Key Concepts

• Identify what line 5 represents on the temperature vs. BTU/lb graph (hint: look at the sloping line above the boiling temperature). • Recall how specific heat (BTU per pound per degree of temperature change) of a vapor behaves when pressure increases. • Compare how latent heat (horizontal segments) changes with pressure versus how sensible heat (sloping segments) changes with pressure.

💭 Think About

• First, decide whether line 5 is showing a latent heat process (constant temperature, changing BTU) or a sensible heat process (changing temperature and BTU). What property does its slope represent? • Think about what happens to the latent heat of vaporization as saturation pressure goes up, and separately what happens to the specific heat of superheated vapor. Are those trends the same or different? • Check some typical steam table values (mentally or conceptually): at higher pressures, does it take significantly more, significantly less, or roughly the same BTU per pound to raise superheated vapor by 1°F?

✅ Before You Answer

• Be sure you are clear that line 4 and line 5 represent different types of heat (latent vs sensible) before choosing an option. • Confirm in your mind whether the units of line 5’s value are BTU per pound per degree (a rate per degree) rather than total BTU for the entire segment. • Double‑check that the choice you pick actually describes a change in specific heat of superheated vapor, not a change in latent heat of vaporization or condensation.
