Answer:
Energy
Explanation:
The easiest way would be to remember that PV=nRT and doing fundamental dimensions on that equation:[tex][nRT]=[PV]=[P][V]=ML^{-1}T^{-2}L^3=ML^2T^{-2}[/tex], so the answer is Energy.
This is because we have to remember that P=F/A, and F has dimensions of mass ([tex]M[/tex]) and acceleration ([tex]L/T^{-2}[/tex]) while A has dimensions of longitude squared ([tex]L^{2}[/tex]), which gives [tex][P]=ML^{-1}T^{-2}[/tex]. Volume has dimensions of [tex]L^{3}[/tex].
We can use any energy formula to know its dimensions, for example, from the Kinetic Energy we know that it must has dimensions of mass and velocity squared, [E]=[tex]ML^2T^{-2}[/tex], which is what we got.
