Question

In what way would a digital thermometer be preferable to those from a liquid-based thermometer?
Digital thermometer readings are easier to use when performing calculations.
Digital thermometer readings can be more readily combined with computer software.
Digital thermometer are inexpensive.
Digital thermometer are less prone to fluctuation.

Answer 1

Correct answers:
- Digital thermometer readings are easier to use when performing calculations.
- Digital thermometer readings can be more readily combined with computer software.

Why:
- Digital displays give direct numeric output, so you can read and use values immediately for calculations.
- Many digital thermometers provide electronic outputs (digital interfaces, data logging, Bluetooth/USB), so they integrate with computers and software easily.

Why the others are incorrect:
- “Inexpensive”: not universally true — some digital thermometers are cheap, but many are more costly than simple liquid (glass/mercury) thermometers.
- “Less prone to fluctuation”: not generally true — digital sensors can show rapid noise or short-term variation; liquid thermometers often have thermal inertia that smooths fluctuations.
