(b) isobaric
(c) isochoric
(d) none of these.
Figure

Answer 1

Answer:

(c) isobaric....

please mark me brainliest XD....

Answer 2

The process on an ideal gas, shown in attached figure, is isochoric

Explanation:

Step 1:

As we know that

P is directly proportional to T, in accordance with the graph

Applying State Equation

We get  

PV = nRT

$P=\frac{n R}{v} T$  

where

n =  physical law which describes the relation between the measurable properties of an ideal gas  

P is pressure

V is volume  

n is  number of moles

R is the gas constant

T is  temperature in Kelvin

Step 2:

Given : P directly proportional to T  

Which means $\frac{n R}{v}$ is a constant , But V still remains constant

Constant v means isochoric cycle  

Therefore the correct answer is Option (c) isochoric
