1.	Which one of the following sets of units represents the smallest and the largest amount of energy respectively ?
Answer» J and ERG erg and cal cal and eV eV and lit atm Solution :Smallest `=` eV and Largest `=` lit atm `1eV = 1.6 XX 10^(-19) J ,1 cal = 4.186 J` ` 1 erg = 10^(-7) J , 1 `lit atm` =101.3 J`
