Description
"Measuring the Temperature of Water" Changes in Temperature and Water PPT Courseware
To measure the temperature of water, we must have a suitable thermometer.
What should I choose?
How to measure water temperature
(1) Hold the upper end 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) The line of sight should be level with the liquid level of the thermometer.
(4) Take the reading when the liquid injection no longer rises or falls.
(5) The thermometer cannot leave the water being measured when reading.
What will happen if you don't follow the correct operation method?
(1) Holding it in the middle will block the scale, and holding a glass bulb will cause the temperature measured not to be the water.
(2) If it touches the container or leaves the liquid surface when reading, the temperature of the water is not measured.
(3) Looking down or looking up will cause the reading to be too large or too small.
(4) The temperature measured when it is not stable is inaccurate.
The general rules for water cooling naturally are:
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 the temperature of the surrounding air.
Therefore, the water temperature hardly changes in a short period of time.
for an object
A decrease in temperature means that the object's heat content decreases;
When the temperature rises, the heat of the object increases.
