A simple calculation will tell you
The heat capacity of water is 41868J/(g·0℃) × volume of water × density × (100℃-temperature of water before heating) = quantity of heat< /p>< p>q=i×i×r×t
Electricity consumption=heat=u×i×t=p×t
1 kilowatt hour = 1 kilowatt hour = 3,600,000 Joules

How to use a mineral water bottle to pump water from the river< /h3>
Experiment 1, inertia experiment: lay the bottle of mineral water flat on the table, pull the bottle hard, and the bubbles in the bottle will move in the direction of the bottle;
Experiment 2, liquid pressure experiment: Place the bottle upright on the table, open the bottle cap, and attach the bottle at different heights. Three holes, observe the water flow speed or landing distance. It can be seen that the greater the depth of the liquid, the greater the pressure;
Experiment 3, atmospheric pressure experiment: Place the bottle upright, open the bottle cap and use a piece of paper to cover the mouth of the bottle and turn it upside down so that the water in the bottle does not flow.
Use the siphon principle.
Fill the mineral water bottle with air and shake it for a while, and he can draw it.
The principle of the siphon is the principle of the connector. The siphon is filled with water, there is no air, the water level at the inlet end is high, and the water outlet is closed with the palm of the hand or other objects. At this moment, the pressure inside the pipe is equal everywhere. Once everything is installed, open the water outlet. Although the air pressure on both sides is equal, the water level at the inlet end is high and the pressure is strong, causing the incoming water to continuously flow out of the outlet.
