What is calorific energy?
Calorific energy refers to the amount of heat energy released by burning a certain amount of fuel. It is commonly used to measure the energy content of fuels such as coal, oil, and natural gas. The higher the calorific value of a fuel, the more energy it can produce when burned.
What is the calorific value of petrol diesel and unleaded petrol?
Fuel Type Higher Calorific Value (Gross Calorific Value - GCV) kJ/kg Btu/lb Diesel 44,800 19,300 kJ/l Btu/gal Kerosene 35,000 154,000 Gas oil 38,000 164,000 Petrol (kJ/kg) 48,000 Petroleum (kJ/kg) 43,000
Explain why some fuels are fossil fuels?
Fossil fuels are made from the remains of ancient organisms like plants and animals that have been buried for millions of years. This organic matter gets transformed into fuels like coal, oil, and natural gas through heat and pressure underground. Their formation process over such a long timescale is what makes them known as fossil fuels.
Why fossil fuels run out in one day?
Fossil fuels are a finite resource that is formed over millions of years from organic matter. They cannot be replenished quickly, so if all the remaining fossil fuels were extracted and used in a single day, it would exhaust the available supply and leave none for future generations. Additionally, the extraction and burning of such vast quantities in a short period would have catastrophic environmental consequences.
What is one way in which fossil fuels and wind power are different?
Fossil fuels are non-renewable sources of energy, while wind power is a renewable source of energy. Fossil fuels contribute to air pollution and climate change through carbon emissions, whereas wind power is clean and does not produce greenhouse gases during operation.
What do you mean by calorific value of fuels and how can you determine the colorific value of solid liquid and gas?
calorific value means the total amount of heat energy evolved when 1gm of the fuel is completely burnt. from the combustion equation find out enthalpy of combustion.then divide the molecular weight to that quantity.
Causes effects and control measures of air pollution?
explain the consequences of over utilization of water resources
What are bio-fuels used for?
biofuels make energy from living things or their waste products
Advantages of fuels?
Advantages of fuels: Easily Available, Produce Large Amount of Energy, High Calorific Value and Stability. The highest consumption rate in todayâ??s world is of fossil fuel.
What is calorific energy?
Calorific energy refers to the amount of heat energy released by burning a certain amount of fuel. It is commonly used to measure the energy content of fuels such as coal, oil, and natural gas. The higher the calorific value of a fuel, the more energy it can produce when burned.
Why can you not fully explain how a torch works?
Because it can be made out of different materials, use different fuels and can be lit different ways. and depending on all of that it can burn different colors and light intensities.
Does adding oxygen increase calorific value of fuels?
No. Oxygen is not a fuel, so it has no calorific value. Some people confuse "combustion" (burning a fuel) with "supports combustion" (allows burning to take place). Oxygen supports combustion, but does not burn itself. Therefore it has no calorific value.
Why is net calorific value is less than gross calorific value?
The lower calorific value or Net calorific value (NCV) which supposes that the products of combustion contain the water of combustion to the vapor state. The heat contained in this water is not recovered.The higher calorific value or Gross calorific value (GCV) which supposes that the water of combustion is entirely condensed. The heat contained in this water is recovered.sayed karar waris
What is in fossil fuels?
In a fossil fuel is different fuels that have been burned
What are different types of alternative fuels?
Biofuels, Algae fuels ect.
What are the consequences of using fossil fuels?
Hurts the environment, and cars that use fossil fuels generally have more problems than electric. Also more expensive to fill
What are the environmental consequences related to obtaining the three major types of fossil fuels?
Burning of fossil fuels releases harmful gases in atmosphere ie NO2 and SO2.
