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

How many calories are required to raise the temperature of 1 g of water by 5 degrees C?
1 calorie is the energy required to raise 1 gram of water by 1 degree C. So it would take 5 calories to raise it by 5 degrees C.
How many Calories are needed to heat up a 2 liter bottle of liquid from 0 degrees to 100 degrees Celsius?
It depends on the liquid contained in the bottle and the material the bottle is constructed from. The definition of a Calorie is the amount of energy required to raise the temperature of one gram of water by one degree Celsius, therefore to heat 2 litres of water (which weighs 2000g) by 100 degrees C = 200.000 Calories. N.B. The water will be at 100 C, to convert into steam, the energy required for phase change must be considered. The effect of the bottle has been ignored in this answer. To add to the confusion: This definition is the "real" calorie as defined and used in physics and chemistry etc. The calorie used in food, exercise etc is really a kilocalory. It is abbreviated kcal, but is often read as calories, not kilokalories. If you mix this up, you get the wrong answer that a liter of cola contains approx 430 calories, but to heat it from 7 to 37 degrees celcius takes 30.000 calories.
How many calories are required to convert 17g of ice at 0 degrees Celsius to liquid water at 32 degrees Celsius?
The simple beginning is that the definition of a calorie is "the energy required to raise the temperature of 1g of water 1°C." Therefore, the energy required to raise 17g of water 32°C: 17*32=544 cal. However, the question asked about ice. There is an extra bit of energy required for the change of physical state. The energy required to convert 1 gram of ice at 0°C to liquid water at 0°C is called the "latent heat" and is equal to about 80 cal. To convert 17g of ice, we multiply this together: 17g * 80cal/g = 1360 cal. So, we add this energy required for the change of state to the energy required to raise the listed quantity to the required temperature and we get 544 cal + 1360 cal = 1904 cal, assuming no heat is lost to the environment. I hope this clarifies some things.
How much heat energy in kilojoules is required to convert 41.0g of ice at -18.0 degrees C to water at 25.0 degrees C?
19.7 kJ
If 405.0 ml of water had its temperature raised by 17.2 degrees celsius how many calories would have been put into the water?
I don't think you actually put calories into the water. You would dissipate thermal energy that could be measured in kCal or calories to heat the water. You may be thinking of the stored thermal energy from the heated water.
How many calories are required to raise the temperature of 1 g of water by 5 degrees C?
1 calorie is the energy required to raise 1 gram of water by 1 degree C. So it would take 5 calories to raise it by 5 degrees C.
How much energy is required to raise 21kg of water by 2 degrees Celsius?
21 Kg = 2100 grams to rise the temperature of this amount of water by 2 degrees Celsius you need 2*2100 = 4200 calories or 17572.8 Joules.
How many Calories equals 350 degrees celsius?
Celsius is a unit of temperature, calorie is a unit of energy. Although temperature and energy are closely related they are not the same.calories required to heat 1kg of Alluminium in 350˚ = 910 × 350 = 318500J = 76 123.33 calories requiredcalories required to heat 1kg of Copper in 350˚ = 390 × 350 = 32 624.28 calories requiredcalories required to heat 0.5kg of Alluminium in 350˚ = (910 × 350)÷2 =159250J = 38061.66 calories requirednotice the difference between heating different materials, and heatingdifferent amounts of the same material makes difference in energyrequired
How much energy is needed to raise the temperature of 2.0 g of water 5.0 degrees C?
The needed energy is 10 calories.
Does nutrition labels list the energy content in food in degrees?
No, it list the energy content in calories, which is the amount of energy to raise a quantity of water by a certain temperature.
How were calories were made?
calories were never "made." they are simply the amount of energy required to raise the temperature one gram of water one degree celsius.
How much energy is required per gram per change in degrees C?
It depends on the specific energy of the substance.
How many Calories are needed to heat up a 2 liter bottle of liquid from 0 degrees to 100 degrees Celsius?

How many joules of energy are required to raise the temperature of 74g of water from 20 degrees to 70 degrees celsius?
15480.80
What kind of energy do calories produce?
Calories don't "produce" energy; calories are a UNIT OF ENERGY.
How many calories are needed to raise the temperature of 10 g of water from 25 C to 35 C?
100 calories. 1 calorie is defined as the amount of energy required to raise the temperature of 1 gram of 1 by 1 degree Celsius. So, if you need to raise 10 grams of water 1 degree, you would need 10 calories of energy. If you needed to raise those same 10 gram by 10 degrees, you'll need 10 * 10, or 100 calories.
Is a green heating system unable to go beyond 68 degrees?
If you are asking why a green heating system will not go above 68 degrees Fahrenheit then one reason is to save energy. The higher the temperature the more energy required to get to that temperature and the more energy required to keep that temperature.
