Thermal expansion of solids, liquids and gases — practice question

The diagram illustrates two liquid-in-glass thermometers $P$ and $Q$. Other than the fact that $Q$ has a capillary tube with a larger internal diameter than $P$, the thermometers are the same. Which thermometer has the larger range and which thermometer has the greater sensitivity?

  • Alarger range: $P$, greater sensitivity: $P$
  • Blarger range: $P$, greater sensitivity: $Q$
  • Clarger range: $Q$, greater sensitivity: $P$
  • Dlarger range: $Q$, greater sensitivity: $Q$
