Heat and Thermal ExpansionHard

Question

The expansion of unit mass of a constant pressure is shown in the diagram. here : -

Options

A.a = volume, b = ^oC temperature

B.a = volume, b = K temperature

C.a = ^oC temperature

D.a = K temperature, b = volume

Solution

Volume can′t be negative.
At constant pressure
V ∝ T or V α (t + 273)
