How much heat does it take to heat 1 liter of water from 20 to 80 degrees?
The calorific value of water is 80cal/degree. so it takes 60*80=2400cal of heat.
How many calories does it take to heat 1 liter of water 1 degree?
It takes 1000 calories to heat 1 litre of water 1 degree C.
Does it take 4180 Joules to heat 1 liter of water?
amount of energy required to heat 1 liter of water completely depends on the desired change in temperature. q = Cg m ∆T ∆T = q/ (Cg x m) = 4180/(4.18 x 1000) = 1 4180 J would heat 1 liter of water by 1 oC
Why does water take so long to warm up?
The specific heat of water determines how much energy is needed to heat water.
How long does it take to heat one liter of water from a heat source?
It depends on the how many degrees you wish to change the water and the wattage of the heater. Obviously a 1500 watt heater will do it faster than a 1000 watt heater. You might want to begin by looking at the heat transfer formula: heat in joules equals mass times change in temperature times specific heat of the material (water in this case).
How long does it take for a heater to heat up the water in your tank?
Less than 3 minutes! It shouldn't take that long
How long does it take for one liter of water to freeze?
It will freeze quicker ina colder temperature. What is the temperature ?
How long does it take water to freeze at 20 degrees?
It depends on the volume of water present, and the heat of the water to start with.
How many btu to heat a 120 liter hot water cylinder?
How hot and how fast? 5,000 btu's will heat it. Not very hot and it will take forever. If you are using it for residential hot water application. Roughly 40,000 BTU's
Why horseshoe cools down slowly in air?
It has two reasons: 1.The specific heat of water is around four times higher than the specific heat of air, that is the water takes the energy from the hot horseshoe 4 times faster at the same temperature. 2. One liter of water contains more molecules than one liter of air, that is there are more mass around the horseshoe in water to take the heat than in air.
How long does it take for the water to start boiling At what temperature does the water boil?
How long it takes water to boil depends on how much heat is being used. Water boils at 100 degrees C
How long will it take 1 watt to heat 1 liter of water 1 degree centigrade?
Roughly 4200 seconds, since the specific heat of water is around 4.2J/gK (ie it takes 4.2 joules to raise 1 gram by 1 Kelvin); 1 litre = 1000 grams, 1 Celcius (centigrade) = 1K, 1W = 1J/s.
