Answer #1

Yes for Same transformation from stage 1 (P1,V1,T1) to Stage 2 (P2,V2, T2), work required will be differed depends on by which process this transformation happened. Process followed is adiabatic, isentropic etc will have different amount of work.

By 1st Law of thermodynamics, Change in heat = Change in Internal energy+Work

For Two same stages, Change in internal energy will be same, its independent of transformation process which is taken to move from Stage 1 to Stage 2. Hence to accomodate different work, heat will be different for different processes.

The same cultural symbol can have the different meanings to different groups. If you change a symbol only slightly it may change its meaning dramatically. Crosses in a math problem or on a church steeple or on fire in someone’s yard all have very different meanings. Can you think of other symbols whose meaning changes with the context it is used in?

Show that the work done by an ideal gas during an isothermal change of state (from initial state 1 to final state 2), in a closed container is given by; 1W2=m.R.T(ln(v2/v1)) A piston-cylinder device contains 0.2 kg of air, initially at 27oC and 100 kPa. The air is then slowly compressed in an isothermal process to a final pressure of 400 kPa. Determine: (a) The work done during this process, and (b) The heat transferred.

Your boss asks you to determine (and quickly) the amount of heat needed to increase the temperature of a gaseous n-octane stream from 25 °C to 800 °C. The stream operates at a flow rate of 125 mol/min with pressure maintained roughly at 1 atm. a)      Due to the time constraint you assume that the heat capacity is independent of temperature. How much heat do you tell our boss is required? b)      Later, you decide to calculate the true amount...
