The variables which determines the thermodynamic behaviour of a system are called thermodynamic variables.
Gases have two specific heat capacities,`C_p `and `C_v`. Why?

The variables which determines the thermodynamic behaviour of a system are called thermodynamic variables. what happens to the internal energy of a gas during an adiabatic expansion?

The variables which determines the thermodynamic behaviour of a system are called thermodynamic variables. What happens to the internal energy of a gas during isothermal expasion?

The variables which determines the thermodynamic behaviour of a system are called thermodynamic variables. Pick out the one which is NOT a thermodynamic variable.(temparature, pressure, work, volume)

The variables which determines the thermodynamic behaviour of a system are called thermodynamic variables. Laplace pointed out that when sound is propagating through a gaseous medium, the change in adiabatic. Show that adiabatic bulk modulus is -gamma_P ?

Why specific heat of gas at constant pressure (C_p) is greater than specific heat at constant volume?

Thermodynamics deals with energy changes of macroscopic system. a) Consider a chemical reaction taking place in a closed insulated vessel. To which type of thermodynamic system does it belong? b) State the first law of thermodynamics. c) 3 mol of an ideal gas at 1.5 atm and 25^oC expands isothermally in a reversible manner to twice its original volume against an external pressure of 1 atm. Calculate the work done. [R = 8.314 JK^-1mol^-1]
