Calories are units of energy. We often associate calories with food, but in fact they apply to any substance that contains energy.
Simply put, 1 calorie of energy or heat can raise the temperature of 1 gram of water by 1 degree Celsius at one atmospheric pressure. 1 calorie is approximately equal to 4. 186 joules (joules are commonly used units of energy in physics).
Most of us associate calories with what we eat or drink, such as "This soda contains 200 calories". In fact, the calories listed on food packaging are calories, which are also written in capital letter C.
It is equivalent to the heat required to raise 1 000 grams of water from 14.5 degrees Celsius to 15.5 degrees Celsius at1atmospheric pressure, which is about equal to the internal energy of 4 186 joules. (1000 calories = 1 calories).
So, actually, this can of soda contains 200,000 calories (but don't worry, it also applies to exercise-when the exercise chart says that you jog for 2 kilometers to burn 100 calories, it is 100 calories).
In English, "calorie" (lowercase) means calorie, which is about 4. 186 joules, and "calorie" (uppercase) means calorie, which is about 4 186 joules.
