WebFigure 2. A heating curve and phase diagram for water. Solution. While anywhere along the line segment BD represents a phase change from solid to liquid, and points Y and Z are both on that line, the correct answer is D. At point Y, the phase change is occurring at the same pressure (1 atm) that was used to construct the heating curve. WebUsing Equation (8) where the specific loss power P s is given by Equation (2) or (7) depending on the magnetic field used (as we have shown above), with the quantities ξ, χ i and τ given by Equations (3), (5) and (6), we calculated the variation of the heating temperature (ΔT h) of the CoFe 2 O 4 nanoparticles and the heating time (Δt o) to reach …
