Question

6.5. What is a p-v dia an indicator dia? tence
define as isotherm
What is the use of P-vdia ? what does the areal
under Pudia represent?​

Answer 1

Answer:

Only two thermodynamic variables are sufficient to describe a system because third variable can be calculated from equation of state of the system.

P-V Indicator Digram is just a graph between pressure and volume of a system undergoing an operation.

When a system undergoes an expansion from state A (P1 V1) to a state B (P2V2) its indicator digram is shown as follows

Intermediate states of system are represented by points on the curve.

The pressure volume curve for a fixed temperature is called isotherm.
