Meaning and Definition
A device that indicates a change in temperature without providing a precise numerical measurement.
An early scientific instrument, precursor to the modern thermometer, used to detect the presence and direction of temperature change, often through the expansion/contraction of air or liquid in a sealed glass tube.

FAQ
Frequently Asked Questions
No. A thermoscope is a specific historical device that shows change, not a numerical value. Using it for a modern thermometer is incorrect.
Its invention is often attributed to Galileo Galilei around 1592, though several Renaissance scientists worked on similar devices.
Not in practical applications. It is primarily used as a teaching tool to demonstrate the principle of thermal expansion or discussed in historical contexts.
A common design was a glass bulb attached to a thin tube, partially filled with water or wine, with the bulb end placed in a container of water. Air expansion in the bulb moved the liquid in the tube.
A device that indicates a change in temperature without providing a precise numerical measurement.
Thermoscope is usually technical/specialized in register.
Thermoscope: in British English it is pronounced /ˈθɜː.məˌskəʊp/, and in American English it is pronounced /ˈθɝː.məˌskoʊp/. Tap the audio buttons above to hear it.
Learning
Memory Aids
Mnemonic
Think: 'THERMO' (heat) + 'SCOPE' (to look at). You 'scope' or look at heat change, but don't measure its exact number.
Conceptual Metaphor
A WITNESS TO CHANGE (rather than a measurer).
