Figure \(\PageIndex{1}\): A typical heating curve for a substance depicts changes in temperature that result as the substance absorbs increasing amounts of heat. Plateaus in the curve (regions of constant temperature) are exhibited when the substance undergoes phase transitions.

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. It can also be defined as a curve whose points are at a constant normal distance from a given curve. [1] .
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.
DEFINITION. Curves C and C are parallel if there is a one-to-one corres pondence between their points such that the tangents at corresponding points are parallel and such that the join of corresponding points is perpendicular to the tangents. This definition was given by Da Cunha (1 ).
Heating curve - shows temperature changes of a substance over time as it is heated. Cooling curve - shows temperature changes of a substance over time as it is cooled. Intermolecular forces - are forces between particles.
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.

Apr 13, 2022 · Equation 8.4.15 shows that the curve of a plot of \(\ln(p/p\st)\) versus \(1/T\) (where \(p\) is the vapor pressure of a pure liquid or solid) has a slope at each temperature equal, usually to a high degree of accuracy, to \(-\Delsub{vap}H/R\) or \(-\Delsub{sub}H/R\) at that temperature.
