The temperature of some water in a bottle can be measured with a/an

thermometer.

The temperature of water in a bottle can be measured with a thermometer.

To measure the temperature using a thermometer, follow these steps:
1. Make sure the thermometer is clean and sterilized if necessary.
2. Place the thermometer in the water. If the water is in a bottle, it can be helpful to insert the thermometer through the bottle's opening.
3. Wait for the thermometer to stabilize, allowing it enough time to accurately measure the temperature.
4. Read the temperature indicated on the thermometer's scale. The scale may be digital or analog (with a mercury or alcohol-filled bulb).
5. Take note of the temperature reading, which is usually indicated in degrees Celsius (°C) or Fahrenheit (°F).

Remember to handle the thermometer carefully and avoid touching the part that goes into the water to ensure accurate measurements.
