The grams of carbohydrate in one apple if the apple has no fat and no protein and provides 72 kcal of energy. what ate the kilocalories or kj?

One calorie is equivalent to 4.184 joules. If an apple has 72 kilocalories of energy, knowing that 1 kilocalorie is equal to 1000 calories, then it has 72000 calories. Then to convert it to joules multiply it by 4.184. Then you have _ joules. Then concvert it to kilojoules by dividing it by 1000, you have 301.248.

the transfer of heat by electromagnetic radiation is called thermal radiation . it is usually carried out by electromagnetic waves in an energy range just below the visible spectrum, which is the infrared range.

so the answer would be radiation.
