Answer Key : (a) -

(a)

(a s) Whenever internal energy of a system decreases, then the temperature always decreases

In an adiabatic expansion work is done by the gas

 is

 Temperature decreases

(b r) For an ideal gas,

(c q) Whenever internal energy increases temperature of the system increases

(d p) During resonance,

In  where resonance takes place
