On a stove it would take about 5 minutes to boil 2 cups of water, depending on the stove and the factors I mentioned before. Usually it’s 2 minutes per cup of water. It would take a lot longer to boil water on a grill. In a microwave, it would take about 1.5 to 2 minutes to boil 2 cups of water.

## How long does it take to boil off 1 Litre of water?

3. Heat source. The heat source also plays a significant role. If, for instance, you attempt to boil say, 1 liter using a regular stove, it will take about 10-15 minutes for the water to reach boiling point.

## How long will it take to heat 2 Litres of water?

The heat is lost to the atmosphere at constant rate 160J/s, when its lid is open. In how much time will water heated to 77∘C with the lid open ? (specific heat of water = 4.2kJ/∘C-kg) ∴Time required =QP=500s=8min20s. Step by step solution by experts to help you in doubt clearance & scoring excellent marks in exams.

## How long does it take to boil 1 Litre of water in a kettle?

1 liter of water boils in an electric kettle in about 4 to 5 minutes. 1 liter of water boils in a microwave in about 3 to 4 minutes.

## Can you boil water 2 times?

When you boil this water once, volatile compounds and dissolved gases are removed, according to author and scientist, Dr Anne Helmenstine. Yet if you boil the same water twice, you risk increasing concentrations of undesirable chemicals that may be lurking in the water.

## How long we should boil water?

If the water is clear: Bring the clear water to a rolling boil for 1 minute (at elevations above 6,500 feet, boil for three minutes). Let the boiled water cool. Store the boiled water in clean sanitized containers with tight covers.

## How long does it take to boil 500ml of water?

I did an experiment where I boiled two cups (500ml) of water in a kettle, and it took 1:30 minutes to reach around 98 C, average.

## How much energy does it take to heat 1000 Litres of water?

24 calorie per second. It takes 1000 calories to raise 1 liter of water one degree C. So apply about 4000 watts for one second to do this.

## How do you calculate the time it takes to heat water?

Using the formula Pt = (4.2 × L × T ) ÷ 3600 you can calculate the time it takes to heat a specific quantity of water from one temperature to another temperature.

## How many watts does it take to heat water?

A typical 50-gallon electric tank runs at 4500 watts.

From above, heating a gallon of water by 1 F takes 8.33 BTU. Heating from 68 F to 104 F would by a 36 F rise, or 36 x 8.33 = 300 BTU to heat 1 gallon of water.

## How many watt hours does it take to boil water?

So 0 degrees C is 273 degrees Kelvin. What c in the equation is, the specific heat capacity. So in water it takes 1200 joule’s to raise a Kg of water by 1 degree K or in degrees C. If this takes 1 min to boil the power required to boil the water equals 96kilo joules/60 seconds =1600 watts or 1.6 kilo watts.

## Is it cheaper to boil a full kettle?

Kettle: around 2p to boil a full kettle: The average kettle holds 1.5 litres of water and uses about 0.1 kWh of electricity to boil for 3 minutes. That’s around 2p every time you boil a full kettle.

## Does it take longer to boil more water?

So when the heat is spreading itself evenly across the water, the larger amount of water would be less hot than the smaller amount of water thus, it would take more time to get the larger amount of water to be as hot as the smaller.

## Is it bad to boil water multiple times?

Generally, boiling water, allowing it to cool and then reboiling it does not present much of a health risk. … It’s best if you don’t let water boil down, which concentrates minerals and contaminants and if you reboil water, it’s better to do it once or twice, rather than make it your standard practice.

## Is twice boiled water bad?

Does twice boiled water taste different? Okay, so we’ve shown that you don’t need to worry about reboiling water more than twice. It’s perfectly safe and will not be hazardous to your health in the short or the long term.

## Can boiled water go bad?

Boiled water can be stored for 6 months at room temperature. This statement relies on adherence to CDC guidelines, which dictate that the water was boiled according to their advisory. It should be stored in sanitized containers and placed in locations with a room temperature not above 70°F (21°C).
