The complete combustion of a small wooden match produces approximately 512 cal of heat. how many kilojoules are produced? express your answer in terms of kilojoules.

We have to covert 512 cal of heat in kilo joules.

As, 1 cal = 0.004184 kJ = 4.184 joules.

Therefore,

Thus, combustion of a small wooden match produces approximately ( in kilo joules ) is 2.142 kJ .

the answer would be 32*f
