This absolute amount of pressure does not play a significant difference.
At high temperatures and low pressures, its results deviate too little.
But at low temperatures and high pressures, it will change significantly and this difference will change from gas to gas.
In the image you can see the difference between some results from both equations.
Fire burning is a combustion reaction, which is a type of reaction that is always EXOthermic (meaning it gives off heat). When the carbon in the wood reacts with the oxygen in the air, it forms CO2 and H2O, releasing heat in the process that escapes the fire place and transfers out to the room.
As for the spread of heat:
“A fire can spread by radiation when the heat travels through electromagnetic waves in the air”

Answer:
To calculate the no. of moles you must know mass and molar mass of the product
Explanation:
no. of moles =mass/molar mass
Answer: False
Explanation:
Molecular formula is the chemical formula which depicts the actual number of atoms of each element present in the compound.
Empirical formula is the simplest chemical formula which depicts the whole number of atoms of each element present in the compound.
Example: 
has similar molecular formula and empirical formula as the elements are already present in simplest of the ratios.
has molecular formula of but 
as the empirical formula.
