Which process is isobaric?

$($A$)$ A $->$ B

$($B$)$ B $->$ C

$($C$)$ C $->$ A

$2.$ Which process is isovolumetric?

$($A$)$ A $->$ B

$($B$)$ B $->$ C

$($C$)$ C $->$ A

$3.$ Which process is isothermal?

$($A$)$ A $->$ B

$($B$)$ B $->$ C

$($C$)$ C $->$ A

$4.$ How does the temperature at point A compare to the temperature at point B$?$

Hint$1$: Ideal gas law still holds, both at point A and at point B$.$ In other words, $=$ and $=$

$.$

Hint $2$: How does the volume at point A compare to the volume at point B$?$ How does the pressure at

point A compare to the pressure at point B$?$
