Question

50 kg of fuel was completely burnt for an experiment. The amount of heat
energy was found to be 2,50,000 kJ. Calculate the calorific value of the fuel.

Answer 1

ʜᴇʀᴇ'ꜱ yᴏᴜʀ ᴀɴꜱᴡᴇʀ

✎ ʜᴇᴀᴛ ᴩʀᴏᴅᴜᴄᴇᴅ → 50ᴋɢ

✎ ᴋɪʟᴏᴊᴜʟᴇꜱ (ᴋᴊ) → 2,50,000ᴋᴊ

ᴄᴀʟᴏʀɪꜰɪᴄ ᴠᴀʟᴜᴇ → $\frac{kJ}{kg}$ → $\frac{Kilojules}{Kilogram}$

ᴄᴀʟᴏʀɪꜰɪᴄ ᴠᴀʟᴜᴇ → $\frac{250000 kJ}{50 kg}$

✎ 5,000 ᴋᴊ/ᴋɢ

Answer 2

Explanation:

✎ ʜᴇᴀᴛ ᴩʀᴏᴅᴜᴄᴇᴅ → 50ᴋɢ

✎ ᴋɪʟᴏᴊᴜʟᴇꜱ (ᴋᴊ) → 2,50,000ᴋᴊ

ᴄᴀʟᴏʀɪꜰɪᴄ ᴠᴀʟᴜᴇ → \frac{kJ}{kg}

kg

kJ

→ \frac{Kilojules}{Kilogram}

Kilogram

Kilojules

ᴄᴀʟᴏʀɪꜰɪᴄ ᴠᴀʟᴜᴇ → \frac{250000 kJ}{50 kg}

50kg

250000kJ

✎ 5,000 ᴋᴊ/ᴋɢ
