## What is the calorific value of petrol?

The calorific value of food indicates the total amount of energy, a human body could generate during its metabolism which is expressed in Kilojoules per 100 grams or 100 ml.

Calorific Value of Fuel.

Fuel Calorific Value Of Fuel( Approximately)
kerosene 45000
Petrol 45000
Methane 50000
LPG 55000

## Which has more calorific value coal or petrol?

Majorly there are three fossil fuels i.e., coal, petroleum and natural gas.

Which fuel has the highest calorific value? A.) Hydrogen gas. B.) Methane. C.) Wood. D.) Petrol.

Fuel Calorific Value (kJ/kg)
Coal 25000-33000
Petrol 45000
Kerosene 45000

## What are the calorific values of coal and petrol Which is better and why?

Answer: The calorific value of coal is about 25,000 – 33,000 kJ/kg, whereas that of petrol is 45,000 kJ/kg. Hence, petrol is a better fuel.

## What are the two types of calorific value?

Gross calorific value (GCV) and net calorific value (NCV) are the terms used in the formula to calculate calorific value of fuel.

## Which fuel has lowest calorific value?

Coal has the lowest calorific value.

## How is calorific value calculated?

Procedure to Calculate Calorific Value

Net Calorific Value (NCV) means lower heating value (LHV) i.e. lower calorific value (LCV) is determined by the subtraction of heat of vaporization of the water vapour from the higher heating value. … Latent heat corresponding to the partial pressure of water vapour in Kcal/kg.

## Which fuel causes least pollution?

Natural gas is the cleanest fuel and causes the least pollution when burnt compared to petrol, diesel and coal.

## What is calorific value of fuel class 8?

(a)The amount of heat energy produced on complete combustion of 1 kg of a fuel is called its calorific value. The calorific value of a fuel is expressed in a unit called kilojoule per kg (kJ/kg).

## What is fuel value?

Fuel value (kJ/g) is defined as the amount of energy released per gram of fuel. … The amount of fuel burned can be determined by difference in mass. Both of these measurements will be used to get the fuel value. Calorimeter Efficiency. The efficiency of the calorimeter must be determined prior to calculating fuel values.
