Answer 1

Answer:

1. Calorific Value

2.petrol

3.Methae

4.Carbon monoxide

5.Hydrocarbons

Answer 2

1] Calorific value is the quantity of heat produced by the complete combustion of a given mass of a fuel, usually expressed in joules per kilogram. It can be defined as the amount of heat energy produced on complete combustion of 1 Kg of fuel

2] Nonconventional energy sources (also called alternative energy sources) are any sources or substances that can be used to produce fuels, other than conventional fuels. These are sources that are continuously replenished by natural processes, including biomass, hydropower, nuclear power, solar energy, and tidal energy.

3] Methane .Natural gas is a naturally occurring gas mixture, consisting mainly of methane.

4]Incomplete combustion occurs when the supply of air or oxygen is poor. Water is still produced, but carbon monoxide and carbon are produced instead of carbon dioxide. The carbon is released as soot . Carbon monoxide is a poisonous gas, which is one reason why complete combustion is preferred to incomplete combustion.

5]Combining hydrogen and carbon produces a group of organic compounds called hydrocarbons. Depending on the specific molecular formula, there can be many different types of hydrocarbons, such as the fuels propane and octane. The simplest hydrocarbon is methane, which has the chemical formula CH4.
