Question

in the very first thermometer .....
is used to measure the heat​

Answer 1

Answer:

Several inventors invented a version of the thermoscope at the same time. In 1593, Galileo Galilei invented a rudimentary water thermoscope, which for the first time, allowed temperature variations to be measured. Today, Galileo's invention is called the Galileo Thermometer, even though by definition it was really a thermoscope. It was a container filled with bulbs of varying mass, each with a temperature marking, the buoyancy of water changes with temperature, some of the bulbs sink while others float, the lowest bulb indicated what temperature it was.

Answer 2

Answer:

Yes

Explanation:

The first illustration of a thermoscope showing a scale, which therefore can be described as a thermometer, was by Robert Fludd in 1638. However, around 1612, Santorio Santorio calibrated the tube and went on to attempt to measure human temperature with his thermoscope.
