What is a major disadvantage of using fossil fuels?
They warm the planet.They release greenhouse gases.They release Carbon Dioxide back into the atmosphere. They therefore help to cause global warming.They also release poisonous gases such as Carbon Monoxide.They are a non renewable resource that releases long sequestered CO2 (a greenhouse gas) into the atmosphere.
What are some alternates to fossil fuels?
Some alternatives to fossil fuels include renewable energy sources such as solar, wind, hydroelectric, and geothermal power. Additionally, biofuels derived from organic materials like crops and algae can also serve as a sustainable alternative to fossil fuels. Nuclear energy is another alternative that does not produce greenhouse gas emissions.
What is an advantage of using solar wind and hydroelectric power instead of fossil fuel?
An advantage of using solar wind and hydroelectric power over fossil fuels is that they are renewable energy sources, meaning they can be replenished naturally. This reduces dependence on finite resources like coal, oil, and gas. Additionally, using these cleaner energy sources can help reduce greenhouse gas emissions and mitigate climate change.
What is a source of energy that needs another source of energy to produce it?
Nuclear energy requires an external source of energy to initiate the nuclear fission or fusion reactions that produce energy. This initial energy input is typically in the form of electricity or another type of fuel to start the chain reaction.
What type of energy is always lost during energy transformations?
The type of energy that is always lost during energy transformations is usually heat energy. This is because some of the energy input is typically converted into heat due to inefficiencies in the system, leading to a loss in usable energy.
What is the block diagram of fossil fuels input to electricity output?
c.
What is the common form of input energy. why?
The common form of input energy is electrical energy because it is versatile, easy to transport, and can be converted into other forms of energy efficiently. Additionally, it is widely available and can be generated from various sources such as fossil fuels, renewable sources, and nuclear power.
What is causing globalwarming?
It is caused by the increased input of CO2 or Carbon Dioxide into the atmosphere by human beings through burning fossil fuels for energy. This traps heat which inturn cooks the Earth.
What is the total energy input into the atmosphere from all sources?
The total energy input into the atmosphere comes from various sources such as solar radiation, geothermal heat, and human activities. Solar radiation is the primary source, providing the majority of the energy input. Geothermal heat from Earth's interior also contributes, while human activities such as burning fossil fuels and deforestation add additional energy to the atmosphere.
What process does the energy comes from?
Energy comes from various sources such as sunlight (solar energy), fossil fuels (coal, oil, natural gas), wind, water (hydropower), nuclear reactions, and biomass (organic matter). These sources provide the input needed for processes that convert the energy into usable forms for activities like heating, electricity generation, and transportation.
Why is the sun considered to be original source of most energy resources?
The sun is considered the original source of most energy resources because it provides the primary energy input for processes like photosynthesis, which creates biomass, and drives wind and ocean currents that can be harnessed for energy. Fossil fuels also derive their energy from the sun, as they are formed from organic matter that originally received energy from sunlight.
What is a major disadvantage of using fossil fuels?
They warm the planet.They release greenhouse gases.They release Carbon Dioxide back into the atmosphere. They therefore help to cause global warming.They also release poisonous gases such as Carbon Monoxide.They are a non renewable resource that releases long sequestered CO2 (a greenhouse gas) into the atmosphere.
Why is there a carbon cost for for the process of cracking a hydrocarbon?
Cracking a hydrocarbon involves breaking larger hydrocarbon molecules into smaller ones, which requires energy input. This energy typically comes from burning fossil fuels, releasing carbon dioxide into the atmosphere and contributing to carbon emissions. This process adds to the overall carbon footprint of hydrocarbon processing.
How does energy efficiency affect global warming?
The higher the fossil power plant efficiency the less input fossil fuel burning and hence the less green house gas emissions and accordingly the less global warming.
Why is a spark of energy requieried to begin the chemical reaction of burning a fossil fuel?
The spark of energy is needed to initiate the combustion process by breaking the bonds within the fossil fuel molecules, creating reactive intermediates that can undergo further reactions with oxygen to produce heat and light energy. This initial energy input is required to overcome the activation energy barrier and start the combustion reaction.
What is the main cause of increased carbon dioxide?
The main cause of increased carbon dioxide in the atmosphere is the burning of fossil fuels such as coal, oil, and natural gas. This releases CO2 that has been trapped in the Earth's crust for millions of years, contributing to the greenhouse effect and global warming.
What is the energy input for a device that provides 20 units of useful energy and has an efficiency of 0.25?
The total energy input can be calculated using the formula: Energy input = Useful energy output / Efficiency Substitute the given values into the formula: Energy input = 20 / 0.25 Energy input = 80 units.
