Hi ! I have been searching but i am not able to find out that is there any reason behind , why 1 liter * atm = 101.33 joules ?
I am asking that why it is equal to 101.33 joules any logical reason or just a constant ?Nugatory said:Are you asking why it comes out equal to 101.33 Joules, or why a pressure (atm) time a volume (liter) gives an energy (joules)?
Oh yes ! ThanksDaniel Hendriks said:https://lavelle.chem.ucla.edu/forum/viewtopic.php?t=729
multiply the gas constant 8.31447 J/mol K and then divide by the gas constant 0.08206 L atm/mol K.
1 L atm = 101.33 Joules
Even though this is not wrong, is just shifting the question to why 8.31 J equals 0.082 L*atm.Daniel Hendriks said:https://lavelle.chem.ucla.edu/forum/viewtopic.php?t=729

In scientific calculations, 1 liter * atm is a unit used to measure pressure. It stands for one liter of gas at one atmosphere of pressure. This unit is often used in the calculation of energy, specifically in the conversion of liters-atmospheres to joules.
The ideal gas law, PV = nRT, relates the pressure (P) and volume (V) of a gas to its temperature (T) and the number of moles (n) of gas present. In this equation, 1 liter * atm represents the unit of pressure (P) and is used to convert the volume (V) of the gas into a standard unit (liters). This allows for the calculation of the number of moles (n) of gas present, which is then used to calculate the energy (joules) of the system.
The conversion factor from 1 liter * atm to joules is based on the definition of the atmosphere as a unit of pressure. One atmosphere is defined as the amount of pressure exerted by a column of mercury that is 760 millimeters high at 0 degrees Celsius. This pressure is equivalent to 101.33 joules of energy per liter.
In the context of the gas laws, pressure and energy are directly related. As the pressure of a gas increases, its energy also increases. This can be seen in the ideal gas law, where pressure and volume have an inverse relationship. When pressure increases, volume decreases, and this results in an increase in energy (joules) within the system.
1 liter * atm is commonly used in real-world applications in the field of chemistry and physics, specifically in the measurement of gases and their properties. It is often used to calculate the energy of a gas in a closed system or to determine the number of moles present in a given volume of gas. This unit is also used in industries such as pharmaceuticals and oil and gas, where precise measurements of gases are crucial for production processes.
