How much gas does it take to boil 1 Litre of water?
To heat 1 liter of water by 1C requires 4.18kJ so you then multiply this by 70 (the temperature difference) and then by 150 (the total amount of water) which gives 43,890kJ. So at 100% efficiency you will need 0.9kg of gas.
How long does it take to boil 1 Litre of water in a kettle?
In general they use an electric kettle. A 1 KW kettle filled with 1 liter of water from the cold supply at 12 deg C takes 1000 gm/liter x 1 calorie per gm times (100 – 12) degrees C x 4.2 joules/calorie times 1 KW /1000 watts times 1 minute / 60 seconds or about 6.2 minutes.
How much energy does it take to boil 500ml of water?
In our kitchen, we need to get those 500 mL of water from room temperature (21C) to boiling (100C) by adding energy – 165,000 Joules (or 0.046 kilowatt hours), to be precise – in the form of heat.
Can I boil water with a candle?
Candles can boil water on their own, but it can be hard because of the relatively low heat they put out in comparison to other heat sources. Candle wax simply can’t get as hot as quickly as other forms of emergency heating, such as camp stoves, can.
What is the SHC of water?
The specific heat capacity of water is 4,200 Joules per kilogram per degree Celsius (J/kg°C). This means that it takes 4,200 J to raise the temperature of 1 kg of water by 1°C. Lead will warm up and cool down fastest because it doesn’t take much energy to change its temperature.
