The energy released by combustion of 1 g of a substance is called the of the substance. the energy released by combustion of 1 g of a substance is called the of the substance. specific heat fuel value enthalpy nutritional calorie content heat capacity

Fuel value.

Explanation:

Hello,

In this case, the fuel value is defined as the amount of energy released by the complete combustion of 1g of a particular mass of the substance called fuel. In such a way, the higher the energy density (fuel value) the less energy is used transporting the fuel.

Specific heat and heat capacity lead to the necessary heat to increase the temperature of 1g of a substance by 1°C. Enthalpy is a thermodynamic quantity related with the total heat content of a system. Nutritional calorie content is the energy provided by a food and heat capacity

Best regards.

In a chemical reaction the total mass of all the substances taking part in the reaction remains the same. Also, the number of atoms in a reaction remains the same. Mass cannot be created or destroyed in a chemical reaction.
