A heating element of resistance r is fitted inside an adiabatic cylinder which carries a frictionless piston of mass m and crosssection A as shown in diagram. The cylinder contains one mole of an ideal diatomic gas. The current flows through the element ?
such that the temperature rises with time t as
#(C)# . the piston moves up with constant acceleration .
#(D)# . the piston moves up with constant velocity.
such that the temperature rises with time t as
Well as the cylinder is adiabatic in nature,it will not release nor accept any heat other than the heat produced by the resistor.
Now.the pressure on the gas is solely due to the atmospheric pressure and weight of the piston,which don't change with the process.
So,it is an isobaric process.
Now,change in internal energy for an isobaric process is given as,
So,the piston will move upward with constant acceleration.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.

- A #5 L# container holds #12 # mol and #9 # mol of gasses A and B, respectively. Every three of molecules of gas B bind to four molecule of gas A and the reaction changes the temperature from #360^oK# to #420 ^oK#. By how much does the pressure change?
