An endothermic process absorbs 138kJ. How many calories of heat are absorbed?

To convert kilojoules (kJ) to calories, you can use the conversion factor: 1 kJ = 239.0057 calories.

Therefore, to find the amount of heat absorbed in calories, you can multiply the given value in kilojoules by the conversion factor:

138 kJ * 239.0057 calories/kJ = 33,033.7896 calories.

Therefore, approximately 33,033.79 calories of heat are absorbed.

To determine the number of calories of heat that are absorbed in an endothermic process, we need to convert the given value of 138 kJ into calories.

To begin, we should know that 1 kilojoule (kJ) is equivalent to 1000 joules (J) and 1 calorie (cal) is equal to 4.184 joules (J).

Here's the step-by-step conversion:

1. Convert kJ to J:
138 kJ * 1000 J/kJ = 138,000 J

2. Convert J to calories:
138,000 J * 1 cal / 4.184 J ≈ 32,976.88 cal

Therefore, approximately 32,977 calories of heat are absorbed in the given endothermic process.

There are 1000 joules in a kJ.

There are 4.184 J in a calorie.
