Question

In the reported figure, heat energy absorbed by a system in going through a cyclic process is ______ πJ.

Options

• 101

• 100

• 105

• 110

Answer 1

In the reported figure, heat energy absorbed by a system in going through a cyclic process is 100 πJ.

Explanation:

In cyclic process,

ΔU = 0

According to the first law of thermodynamics,

δQ = δW + ΔU

δQ = δW = Area = πr₁r₂

⇒ π[10 × 10³] [10 × 10^-3] = 100πJ
