Why can kerosene and ethanol be used as fuels?
This can be answered on many different levels. They both burn and give out a good amount of heat is probably the simplest. In more scientific terms, they both contain chemical energy which is released when they burn. More practically, they both ignite easily and burn quite cleanly.
What is the specific heat capacity of ethanol and how does it affect its ability to absorb and release heat compared to other substances?
The specific heat capacity of ethanol is 2.44 J/gC. This means that ethanol can absorb and release heat more efficiently compared to other substances, as it requires less energy to change its temperature. This property makes ethanol a good candidate for use in applications where heat transfer is important.
Why is ethanol liquid?
Ethanol is a liquid at room temperature due to its intermolecular forces. The strong hydrogen bonding between ethanol molecules requires more energy to break the bonds, keeping it in a liquid state.
Why does kerosene burn for longer than methylated spirits?
Kerosene has a higher energy density than methylated spirits, which allows it to burn for a longer period of time. This means that more energy is released when kerosene burns compared to methylated spirits, resulting in a longer-lasting flame.
Which is more flamable petrol vs kerosene?
Petrol is more flammable than kerosene because petrol has a lower flash point and autoignition temperature. This means petrol is more likely to ignite at lower temperatures compared to kerosene.

What fuel produces more energy per gram burned- Ethanol or paraffin?
Paraffin produces more energy per gram burned compared to ethanol. This is because paraffin has a higher energy density due to its chemical composition, which allows it to release more energy when combusted. Ethanol, on the other hand, has a lower energy content per gram.
How does ethanol hurt the environment?
It takes more energy to produce ethanol than the fuel itself yields.
Is kerosene lamp a renewable energy source?
Kerosene is a collection of hydrocarbons derived from crude oil a nonrenewable resource which will run out. So at the moment Kerosene is not a renewable source of energy. However work is currently underway to make use of various plants which can be used to create other hydrocarbons such as ethanol and break these down to basic molecules then through a process known as reforming it is possible to make these simple hydrocarbons become more complex ones such as the components of kerosene. So in the future Kerosene along with all other hydrocarbons could become renewable and become a source of burnable energy as new chemical techniques are formulated.

Why isn't alcohol production from biomass energy efficient?
distillation. Boiling the solution requires more energy than the energy content of the ethanol present.
Does kerosene release more soot than petrol?
It produces less soot. Kerosene is refined one more time then petrol and so this makes it more pure. Its like comparing olive oil and extra virgin olive oil.
Why does kerosene burn for longer than methylated spirits?
Kerosene has a higher energy density than methylated spirits, which allows it to burn for a longer period of time. This means that more energy is released when kerosene burns compared to methylated spirits, resulting in a longer-lasting flame.
Is methanol a volatile liquid at room temperature true or false?
ethanol Edit- this would be methanol because ethanol is a 2-carbon chain compared to the 1C in ethanol, and therefore has more intermolecular forces. As a result, molecules of ethanol would need more energy to break these intermolecular forces to be in a gaseous phase.
Which is more flamable petrol vs kerosene?
Petrol is more flammable than kerosene because petrol has a lower flash point and autoignition temperature. This means petrol is more likely to ignite at lower temperatures compared to kerosene.
What is the hypothesis about specific heat of ethanol and copper?
The hypothesis could be that the specific heat of ethanol is lower than that of copper, based on their different molecular structures and compositions. This would suggest that copper requires more energy to change its temperature compared to ethanol for the same mass.
