Question

Heat energy absorbed by a system going through a cyclic process as shown in figure is

a) 10⁷ pi Joule
b) 10⁴ pi Joule
c) 10² pi Joule
d) 10^-3 pi Joule​

Answer 1

Answer:

it is in Google only okkkkkkkkkkkkkkkkkkkkkkkkk

Answer 2

Answer:

C

Explanation:

Since process is cyclic, change in internal energy ΔU=0

Applying first law of thermodynamics,

ΔQ=ΔU+ΔW

ΔQ=ΔW = Area under the ellipse= πab

Here, length of semi major axis=a=10=b=length of semi minor axis

Hence, heat absorbed= 10
