State first law of Thermodynamics. Heat (q) and work done (w) individually are not state functions but their sum is always a state function. Explain. Why?

Some properties of a system are state functions. q and W are not state functions. But (q+W) is a state function. Why?

A thermodynamic state function is a quantity.

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]

A single pole doesn't exists"State this function is true or false.

What are nuclear pores? State their function.
