What is the calorific value of LPG?
Think about which fuel produces the most heat.
Name one solid fuel.
This fuel is commonly used in many households.
What is the calorific value of coal?
Consider the range provided in the section.
True or False: LPG produces more pollutants than coal.
Evaluate the environmental impact of both fuels.
If you have 10 kg of cow dung and 5 kg of LPG, calculate the total energy produced if cow dung gives 7000 kJ/kg, and LPG gives 55000 kJ/kg.
Break it down by calculating the energy from each fuel separately.
A household using coal emits 10 times more CO2 than a household using LPG. If the LPG household emits 100 kg of CO2 per month, how much does the coal household emit?
What multiplier do we need to consider for the emissions?
