Assuming that the water is at 25 degrees C to boil one litre liter of water you would require 75000 cal or 3138. To be heated to boil Quantity 1 L Sensible heat 1 kg 100 - 25 1 spheat 75 KCal Latent heat to boil 1 L or Kg 540 K Cal Total heat required 615 KCal Add about 5 to 10 heat losses 25K views View upvotes Ruben Valenzuela BA in astrophysics UC Berkeley co 1992. Show all your calculations.

Follow the above instructions and calculate the actual cost of boiling 1 litre of water. Water at home temperature is 60 F it will boils at 212. Over 5 minutes this corresponds to 722W 605 87 KW.

Thermal Efficiency and Improvements. Note that the entire power output of a typical electric rangeoven is about 8 kW so in practice it isnt really possible to boil away 1L of water without unusual equipment. How do you calculate the amount of energy required to maintain a water temperature of 100 degrees C over a period of 5 mins.

So it costs Ksh1377 to boil one litre of water using electricity. 00872kWh will cost158000872Ksh1377. Remember we need 00872kWh to boil one litre of water regardless of the method we are using.

To heat 1 liter of water by 1C requires 418kJ so you then multiply this by 70 the temperature difference and then by 150 the total amount of water which gives 43890kJ. Try multiplying these therms together until you get units in calories. The specific heat of water is 1 calorie per gram C the density of water is 1 gram per milliliter 1 liter is 1000mL and your temperature change is 80C boiling point - starting point 100C - 20 C.

Using Gas LPG One KG of LPG gas has 136 kWh of energy. And 1 calorie equals 4184 Joule. CDC recommends making water microbiologically safe to drink by bringing it to a rolling boil for one 1 minute.
