It takes 1000 calories to heat 1 litre of water 1 degree C.
Yes, your body uses a thermal energy known as caloric energy called "calories." A calorie is the amount of thermal energy required to heat one gram of water by one 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.
2.4705 watts/hour
(110 calories) plus (heat lost from the container during the procedure)
A quart of water is 946.35 cubic centimeters and since density of water is 1 gram per cubic centimeter the weight of a quart of water is 946.35 grams. Heat required = (mass) x (specific heat of substance) x (temperature differential) In our case it would be 946.35 x 1 x 38(assumed degrees centigrade) = 35961.3 cals
Nutritionally, none at all. If you are talking about calories as in weight loss and diet, water hasn't got any calories. Thermodynamically, the calorie as a unit of energy is deprecated in favor of the Joule. It takes 1000 calories (or one kilocalorie, also known as one Calorie) to raise the temperature of 1000 g of water one degree C. Because 1 kg of water is approximately one liter, you can get one Calorie (1000 calories) of heat energy per degree C from a liter of hot water as it cools. (Recovering that heat as usable energy is a different matter entirely.)
200000 calories. 1 gm of water needs 1 cal(calorie) to raise it's temperature through 10C. Now, density of water = 1gm/ml at 40C and we assume that it's density is same at 00C. So we have 2000gm of water. For raising temp by 10C we need 2000 cal. For raising temp by 1000C we need 2000 x 100 cal = 200000 calories

The answer is 2 calories.
The calorific value of water is 80cal/degree. so it takes 60*80=2400cal of heat.
1 litre for 1 degree in 1hour is 1,16 kW/h
A calorie of energy (NOT to be confused with a Calorie, they are different so watch the caps) is the amount necessary to heat 1 gram of water 1oC, so 30 calories are needed to heat 30 g of water 1 degree. To heat it 70oC would take 2100 calories (or 2.1 Calories) of energy.
The specific heat of water is 4.179 Joules per gram per degree Centigrade. The density of water is 1 gram per cubic centimeter, so one liter is 1000 grams. This means it takes 4179 Joules to raise one liter one degree Centigrade.
300 calories, which is equal to about 1255.2 joules
(5)(3)= 15 calories. 1 calorie is the energy (heat) to raise 1 gram of water by 1 degree celsius, so 5 grams of water (3 degrees Celsius) = 15.
103 calories. The heat of fusion of water is 80 cal/g and it takes one calorie to change the temperature of 1 g of water by 1 degree. 80+23=103 calories
