"Measuring the Temperature of Water" Changes in Temperature and Water PPT

Part 1: How to measure water temperature

Which thermometer should you choose to measure the temperature of water? What are the requirements and regulations?

Generally speaking, the temperature of liquid water will be between 0°C and 100°C. Therefore, to measure the temperature of water, you need to choose a thermometer with a measurement value in the range of 0°C to 100°C.

How to measure water temperature

1. Hold the top of the thermometer in your hand.

2. Immerse the lower end of the thermometer in the water without touching the bottom and wall of the container.

3. Keep your sight level with the liquid level of the thermometer.

4. Take the reading when the liquid column no longer rises or falls.

5. The thermometer cannot leave the water being measured when reading.

Measuring the temperature of water PPT, Part 2: Measuring the temperature of water

Use a thermometer to measure water at four different temperatures and record the measurement data.

Water temperature measurement record

Are there differences between groups measuring the temperature of the same water?

What might be the cause of these differences?

Has the water temperature changed? How? What does the change in water temperature indicate?

The greater the temperature difference, the greater the cooling rate.

The warmer the water, the faster the temperature drops.

The temperature of tap water is the same as that of the surrounding air, and the water temperature hardly changes in a short period of time.

For an object, when the temperature decreases, it means that the heat of the object decreases; when the temperature rises, it means that the heat of the object increases.
