Question 1 of 27070

Which of the following filled thermal systems used as a temperature transmitting/receiving system usually is associated with a display with a non-uniform scale?

🔍 Key Concepts

• Relationship between pressure and temperature in different states of matter (liquid, vapor, gas, mercury) • How linear or non-linear expansion/pressure change affects the scale on an indicator • Which filled systems tend to have a linear response and which tend to be non-linear

💭 Think About

• Think about which type of filled system has a pressure–temperature relationship that changes more rapidly over part of the temperature range, causing the scale markings to bunch up or spread out • Consider which systems are commonly used where a uniform (evenly spaced) scale is important, and which are tolerated even if the scale is non-uniform • Ask yourself: in which system does the working fluid change phase (for example, from liquid to vapor) and how would that affect the way the scale is marked?

✅ Before You Answer

• Identify which option involves a phase change over the operating range – this often leads to a non-linear response • Recall that a linear relationship between temperature and pressure/volume usually gives an evenly spaced (uniform) scale • Before choosing, match each system type with whether it is mostly linear or strongly non-linear over the measuring range
