Want this question answered?
The calorific value of water is 80cal/degree. so it takes 60*80=2400cal of heat.
It takes 1000 calories to heat 1 litre of water 1 degree C.
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
The specific heat of water determines how much energy is needed to heat water.
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).
Less than 3 minutes! It shouldn't take that long
It will freeze quicker ina colder temperature. What is the temperature ?
It depends on the volume of water present, and the heat of the water to start with.
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
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 it takes water to boil depends on how much heat is being used. Water boils at 100 degrees C
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.
