What is the chemical formula of calories?
The is not chemical formula for calories. The word 'Calories' is an old fashioned measure of energy. Its modern name is 'Joules'.
Heat required to convert 10 g of H2Os at 1 Celsius compared to changing 100 g of H2OS by 1 Celsius?
A calorie is the amount it takes to heat one gram of water one degree Celsius. So to heat 10 g one degree, it would take 10 calories, same goes for the 100 g.
Calculate the amount of heat released when 50 g of steam at 100 celsius hits the skin condenses and cools to a body temperature of 37 celsius?
water's specific heat is 1 calorie/mL/degree celsius. if you assume the density is 1 g/mL then we have 50 mL of material going from 100 to 37 degrees C. So take Mass X Change in Temp X Specific heat and that is your answer.
What do you do when a customer was given the wrong amount of change?

How many calories should a 120lb person have?
If it's a woman then I would say the correct amount of calories for a healthy diet is 1,700 calories. For a man it varies. 2,000 calories is a healthy amount for a man.
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 many calories of heat would it take to raise the temperature of 256 grams of water from 20 degrees to 99 degrees?
A calorie is the amount of heat you need to raise the temperature of one gram of water by one degree Celsius. Assuming you are raising the temperature of the water from twenty degrees Celsius to ninety-nine degrees Celsius, it would take 20,000 calories. To calculate this, subtract 20 from 99. This is the amount of degrees you need to raise the temperature of the water by. Then multiply that number by 256, the amount of water in grams. You should get 20,244 calories. In significant digits, your answer should be 20,000 calories.
Is thermal energy measured in Celsius?
No. Temperature is measured in degrees celsius. Thermal energy, which causes temperature change, is measured in calories or british thermal units.

What is the difference between calories and kilo calories?
One calorie (cal) is the amount of heat required to raise the temperature of 1 g of water through 1 ° C (from 14.5-15.5 ° C). In real life, the kilocalorie (1000 calories) is used (the amount of heat required to raise the temperature of a whole  kilogram of water through 1 ° C) because it's easier to conceptualize and use in practical applications.
How is the measurement of calories in food determined?
Food is burned to see how much energy is given off. The food is places in a sealed container and burned to measure the rise in water temperature. The amount of energy given off is the amount of calories in the food.
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.
What do calories measure?
