mate a litre..(not a liter!) refers to an amount of liquid not gas and there is not a set amount of moles in a litre as the volume of gas can change with regards to pressure and temprature as shown in the equation PV/T=constant (p=pressure, V=volume, T=temprature)
I'm currently studying A2 physics and I'm stumped on a particular question within a past paper involving internal energy of air. The question is as follows:
Estimate the internal energy of the air in a room of volume 24m^3 at a temperature of about 20˚C. Assume that the air behaves as an...
