Identify the number of correct statements out of the following.

(i) Total energy of universe remains conserved but entropy of universe always increases for natural process

(ii) Pressure is an extensive property

(iii) Temperature is a state function

(iv) Addition of two path function can provide a state function.

According to the second law, the total entropy of the universe is continuously increasing whereas according to the first law, total energy of universe remains conserved.

Pressure is intensive property which independent of amount of material. It can be easily calculated.

Temperature is a state function as it is one of the values used to define the state of an object.

State functions are thermodynamic properties whose values are determined solely by the system's starting and ending states, not the path followed.
