Question

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

Answer 1

Take 138 kJ divide it by 4.184 = 32.98 kcal = 3298 calories

Answer 2

Answer: 32982 calories

Explanation:

Endothermic processes are those processes in which heat is absorbed and exothermic processes are those processes in which heat is released.

Standard units for heat measurement are Joules and calories wherein

1 joule = 0.239 Calorie.

Now 1 kJ = 1000 Joules

Therefore 138kJ =
`138*1000=138000Joules`

As 1 Joule is equivalent to 0.239 calorie

138000 Joules are equivalent to=
`(0.239)/(1)* 138000= 32982 calories`
