`0.80 `gram of petroleum was burnt in a bomb calorimater which contains `2.5 kg` of water and has water equivalent `500gram` The rise in temperature was `5^(@)C` Find the calorific value of petroleum

0.75 gram of petroleum was burnt in a bomb calorimeter which contains 2 kg of water and has a water equivalent 500 gram. The rise in temperature was 3^(@)C . The calorific value of petroleum is 10^(n) cal/g. Determine the value of n.

What is calorific value of petroleum if 0.25 g of petroleum is burnt in a calorimeter containing 3 kg of water and having a water equivalent of 400 gm. The rise in temperature is 10^@C

When 0.2 g of 1-butanol was burnt in a suitable apparatus, the heat evolved was sufficient to raise the temperature of 200 g water by 5^(@)C. The values of enthalpy of combustion and calorific value of 1butanol are [kcal]

When 0.400 kg of water at 30^(@)C is mixed with 0.150 kg of water at 25^(@)C contained in a calorimeter, the final temperature is found to be 27^(@)C , find the water equivalent of the calorimeter.

The heat liberated when 1.89 g of benzoic acid is burnt in a bomb calorimeter at 25^@C increase the temperature of 18.94 kg of water by 0.632^@C . If the specific heat of water at 25^@C is 0.998 cal/g-deg, the value of the heat of combustion of benzoic acid is

If 4.5kg of fuel completely burnt and amount of heat produced stands measured at 1,80,000 KJ. What is the calorific value?
