The plot 1V2 vs P for ideal gas at constant T and n is shown by graph 4.
This shows exponential decrease.
The plot V vs 1T for ideal gas at constant P and n is shown by graph 3.
This shows exponential increase.
The plot log P vs log V for ideal gas at constant T and n is shown by graph 3.
This shows exponential increase.
The plot V as 1P2 for ideal gas at constant T and n is shown by graph 1.
This is a straight line with a negative slope.
