A contour line that corresponds to values measured at identical temperatures. For example, curves on a plot of gas pressure measured at different volumes in a constant temperature bath are isotherms.

Scientific method

Chemistry; General chemistry

An inefficient but highly successful method of knowledge construction based on experimental testing of hypotheses .
