An isotherm curve is a line on a graph that represents a constant temperature. It shows the relationship between temperature and another variable, such as pressure or volume. Isotherms are commonly used in thermodynamics to analyze the behavior of gases.
The symbol for an isotherm is a dashed line on a graph that represents a constant temperature measurement.
Above the 10 degree isotherm: Brazil and Democratic Republic of the Congo. Below the 10 degree isotherm: Australia and Venezuela.
At a given temperature, the extent of adsorption will increase with the increase of pressure of the gas. The extent of adsorption is measured as x/m, where mi= is the mass of adsorbent and x that of adsorbate. At low pressure, x/m varies linearly with p. As per Freundlich adsorption equation Taking log both sides of the equation, we get, At low pressure, x/m=kP At high pressure, x/m=kPo This is called Freundlich adsorption isotherm at a constant temperature. Freundlich isotherm fails at high pressure and is only for physical adsorption. Langmuir isotherm is represented as x/m=ap/(1+bp) (a and b are constants) At very high pressure,(bp>>1) x/m=a/b At very low pressure,(bp<<1) x/m=ap

One region where hypothetical isotherm patterns can be observed is in the tropics, near the equator. In this region, temperatures remain relatively constant throughout the year, leading to isotherms that are parallel to the equator. This phenomenon is influenced by the consistent angle at which sunlight strikes the Earth's surface at the equator, resulting in minimal variation in temperature.
