PhysicsHardsingle choice

Water at $4^{\circ}$ C has zero volume expansion coefficient ( $β = 0$ ). For water at that temperature, using $C_{p} - C_{v} = \frac{T V β ^{2}}{κ _{T}}$ :

Options:

Answer:

Solution:

With $β = 0$ the difference vanishes. For all other temperatures $C_{p} > C_{v}$ , since $β^{2} > 0$ . C.
