think:

Which thermometer should you choose to measure the temperature of water?

The temperature of liquid water will be between 0℃~100℃. Therefore, you should choose a thermometer with a measurement value in the range of 0℃~100℃

How to measure water temperature

Hold the top of the thermometer in your hand.

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

Keep your eyes level with the liquid level of the thermometer.

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

The thermometer cannot leave the water being measured when taking readings.

Does the water temperature change? How?

Answer: 1. Except for tap water, the temperature of other types of water has dropped.

2. The temperature of hot water drops quickly, while the temperature of warm water drops slowly.

3. The higher the temperature of the water, the faster it will drop initially.

Through experiments we found:

1. The greater the temperature difference, the greater the cooling amplitude.

2. The higher the water temperature, the greater the temperature drop.

3. The temperature of tap water is the same as that of the surrounding air, and the water temperature will not change in a short period of time.

If one hour passes, what will the temperature of the four glasses of water be?

If half a day passes, what will be the temperature of these four glasses of water?

If one day passes, what will be the temperature of these four glasses of water?

If two or three days pass...will the water temperature drop indefinitely?

If you put this water into the freezer compartment of a refrigerator, what will happen to the water temperature?
