The specific heat capacity is in the equation. If it takes 1 min to boil the water, it will take 1600 watt hours or 1.6 kilo watt hours.
Can you boil water in a 700 watt microwave?
A 600-700 watt oven will boil water in 2½ to 3 minutes. An oven with more wattage will boil water in less time.
How much energy does it take to boil 1 gallon of water?
One BTU is the amount of heat energy required to raise one pound of water by 1ºF. Water weighs 8.33 pounds per gallon so we can calculate that one gallon of water requires 8.33 BTU to raise the temperature 1ºF.
Does it take a lot of energy to boil water?
Explanation: In order to cause water to increase in temperature, the energy being put into the water first needs to break hydrogen bonds between the water molecules. Hydrogen bonding in water is significant, so it takes a significant amount of energy to overcome them.
How long does it take to boil water in a 1000 watt microwave?
If you plan to boil more than one cup, you should expect boil time to be longer: 1,200 watts: 1.5 minutes. 1,000 watts: 2 minutes.
How long should you boil water to purify?
Boiling is sufficient to kill pathogenic bacteria, viruses and protozoa (WHO, 2015). If water is cloudy, let it settle and filter it through a clean cloth, paperboiling water towel, or coffee filter. Bring water to a rolling boil for at least one minute.
How many kWh does it take to boil 1 Litre of water?
Based on the above answers and examples, to boil 1 litre of water from 20C to 100C, requiring 0.183 kWh of either electricity or gas, at todays energy prices GAS is 68% cheaper than electricity.
How long does it take to boil off a gallon of water?
How long does it take a gallon of boiling water to evaporate? If we boil water it takes, for example, 5 minutes to reach the boiling point. If we continue heating, it will take another 20 minutes or so before the water has completely evaporated (which is good, because it gives us time to save our kettle).
How much does it cost to boil a gallon of water?
It is generally accepted that it costs about 1¢ to 2¢ to heat a gallon of water. The exact amount will depend on the efficiency of your water heater, whether you use gas or electric and exactly what your electric or gas costs are.
What happens when you heat water to 100 degrees Celsius?
Boiling point depends on pressure. At sea level, water boils at 100 °C (212 °F) and freezes at 0 °C (32 °F). … But, whatever the boiling point is, when water reaches it and undergoes a phase transition into water vapor (steam), the temperature stops rising. You can crank the heat as high as you like.
Why is energy needed to boil water?
Boiling water is an endothermic process, which supplies heat to the water molecules, increasing their potential energy. … Once the intermolecular bonds are broken, any extra heat increases the kinetic energy of the system and the molecules of the water vapor move faster as the temperature increases.
When water boils does it release or absorb energy?
The amount of energy absorbed when a substance boils, and released when the same amount of substance condenses, is the same. The phase transition is solid to gas, so energy will be absorbed. The process involves the ice melting to water, the water heating from 0 °C to 100 °C, then the water boiling to steam.
