Phase diagrams are combined plots of three pressure-temperature equilibrium curves: solid-liquid, liquid-gas, and solid-gas. These curves represent the relationships between phase-transition temperatures and pressures.

Two definitions of a parallel curve: 1) envelope of a family of congruent circles, 2) by a fixed normal distance. The parallel curves of a circle (red) are circles, too. A parallel of a curve is the envelope of a family of congruent circles centered on the curve. It generalises the concept of parallel (straight) lines.
Introduction to the Heat Curve. Before we take a look at what a heat curve is, we must first understand what can happen when heat is added to a system. Wize Concept. When heat is added to a system, the system can EITHER:
Jun 6, 2017 · To read a meniscus, you first need to see what type of meniscus your liquid forms. If the meniscus is a concave meniscus, read at the lowest level of the curve. If the meniscus is convex, take your measurement at the highest point of the curve.
Heating curves provide valuable information about the thermal properties of substances, including their specific heat capacities, latent heats of fusion and vaporization, and temperature ranges over which phase transitions occur.
Examples: - the curves parallel to a line are the lines parallel to this line (!) - the involutes of a curve are parallel to one another. - the toroids are the parallel curves of the ellipse. - the Cayley sextic is one of the parallel curves of the nephroid. - The parallel curves of the parabola x ² = 2 p y are the curves parametrized by:

A curve connects the experimental points and shows the trend in the relationship. For example, the cure in Fig. 1.6.2 tells that the pressure decreases as the volume increases.
