The time it takes to heat one liter of water from a heat source depends on the power of the heat source and the starting temperature of the water. On average, it can take 4-6 minutes to heat one liter of water on a stovetop or in a microwave.
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.
Less than 3 minutes! It shouldn't take that long
The time it takes for one liter of water to freeze will depend on various factors such as the temperature of the surroundings and the initial temperature of the water. Generally, it can take a few hours to freeze completely in a standard home freezer at around -18 degrees Celsius.
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.
Assuming 100% efficiency, it would take approximately 6.7 hours to heat 500 liters of water with a 3kW element. However, in reality, the heating process may take longer due to factors like heat loss and initial water temperature.
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.
