What is a calorie?

Answer 1

A calorie is the amount of energy it takes to raise water (100 mL, I think) by 1 degree Celsius.

Answer 2

Unit of energy. In food and nutrition, a measure of the energy released by food on absorption by the body. There are calories and Calories. A Calorie is a kilocalorie. Human beings need approximately 2000 Calories per day through food.

Answer 3

a calorie is the amount of energy needed to increase the temperature of 1 ml of water 1 degree Celsius.

In regards to food, a calorie is actually a kilocalorie, or 1000 of the calories described above.

Answer 4

its a measurement. just like a metre is a measurement of length, a calorie is now an old fashioned unit of measuring energy, its modern day replacement is called the Joule (both are often seen printed next to each other on cereal packets in the nutritional info on the side Cal= calorific value, and kJ=kilo-joules. both are scientifically defined as the amount of energy an object has

Answer 5

What is a Calorie, Anyway?
What is a calorie? And why is this term important when we're talking about weight? A calories is the amount or measurement of heat necessary to raise the temperature of one gram of water one degree on the Celsius scale.

Excuse me? What does this have to do with why my pants won't fit?

A calorie is also the unit of measurement of energy produced by food when it is oxidized, or used, in the body. Calories are like fuel for our bodies. We need them for our bodies to run. But if we pump more fuel into our bodies than we need for the amount of activity we do, the excess fuel just sits there. Your body will store this excess, unused fuel. It may store it as muscle, if you perform enough physical, muscle-building exercises such as weightlifting, or it may store it as fat.

Answer 7

a calorie is a unit of heat or energy.
I think it is the energy needed to raise the temperature of 1 cubic cm of water , 1 degree C at Std temp and pressure.

You need to maintain a balance between the amount of calories you take in (food) and the amount of calories you use (exercise). You "burn" your body's fuel - calories - when you perform physical activities, and you also burn calories just by sitting still, breathing and living each day.

If you perform enough physical activity, you may increase the amount of calories (or energy units) you burn each day and raise the amount of calories (or energy units) you need each day. So a person who is physically active can eat more calories each day without gaining weight, because this person uses the fuel he or she pumps in, instead of storing it as fat.

Each person is different when it comes to the amount of calories he or she needs each day. The amount of calories a person needs for fuel varies according to age, height, gender, amount of physical activity and other factors.

Answer 9

the amount of energy to change 1 gram of water 1 degree C

Answer 10

the amt of energy needed to raise 1 gram of water 1 degree Celsius (spelled with a capital 'C' its enough energy to raise 100 grams 1 degree or 1 gram 100 degrees)
