Questions: 3.25 kcal is the same amount of energy as 13600 J 3.25 J 777 J 13.6 J 0.777 J

Solution Steps

To convert kilocalories (kcal) to joules (J), we need to know the conversion factor. The conversion factor is \(1 \, \text{kcal} = 4184 \, \text{J}\).

Multiply the given energy in kilocalories by the conversion factor to convert it to joules: \[ 3.25 \, \text{kcal} \times 4184 \, \text{J/kcal} = 13598 \, \text{J} \]

Compare the calculated joules with the options provided:

• 13600 J
• 3.25 J
• 777 J
• 13.6 J
• 0.777 J

The closest value to 13598 J is 13600 J.
