Galileo Galilei invented the first water thermometer. He created it by adding droplets of alcohol in the water. This is so the liquid is less denser and can detect changes in temperature.
If surrounding water temperature is lower than the water in the thermometer, heat will transfer from the water in the thermometer to the colder water causing the liquid in the thermometer to drop.
When a thermometer enters cold water, the temperature reading on the thermometer will decrease as the thermometer adjusts to the temperature of the water. The liquid inside the thermometer will contract and move down the scale, indicating the lower temperature of the cold water.
The question must be asked carefully. If the thermometer is in water ice and there is no liquid water, and there is one atmosphere of pressure, the thermometer can read anything from the freezing point of water and lower, depending on the range of the thermometer. If the thermometer is in a stable mix of water and ice, it will read the freezing point of water.

The first person credited with inventing the thermometer in 1593 was Galileo Galilei, an Italian scientist and astronomer. He developed a device called the thermoscope, which later evolved into the modern thermometer.
The temperature of the water in the tub before the measurement is the same as the temperature measured by the thermometer once it has equilibrated. However, there may be a small delay between when the thermometer is first introduced and when it reaches the actual water temperature due to thermal equilibrium.
Charles WingerThe Thermometer was invented by Galileo Galilei in 1593. His thermometer consisted of water in a glass bulb; the water moved up and down the bulb as the temperature changed.
The first water thermometer was invented in the 16th century. In 1593, Galileo Galilei improved the existing thermoscope by inventing a basic water thermometer.
That depends on how hot the water is in the cup. Use the thermometer to measure it and see.
Galileo made the thermometer in 1593.
You can measure the temperature of water using a thermometer. Insert the thermometer into the water and wait a few seconds for the reading to stabilize. The temperature displayed on the thermometer is the temperature of the water.
