What is the difference between azeotropic and near-azeotropic refrigerant blends?
Azotropic will only have one boiling or condensing point for each system pressure negligible fractionation or temperature glide will occur Zeotropic will have a range of boiling and condensing points for each system pressure noticeable fractionationand glide will occur.
Define a near-azeotropic refrigerant blend and give two examples.?
a blended refrigerant with less than 10F temperature glide, 41oA and 404A are examples.
What is the difference between zeotropic and near-azeotropic?
zeotrope is a liquid mixture that shows no local maximum or minimum when vapour pressure is plotted as a function of composition.[1] Such a mixture is separable into its component parts by fractional distillation azeotropic distillation[1] is any of a range of techniques used to break an azeotrope in distillation. In chemical engineering, azeotropic distillation usually refers to the specific technique of adding another component to generate a new, lower-boiling azeotrope that is heterogeneous (e.g. producing two, immiscible liquid phases), such as the example below with the addition of benzene to water and ethanol. This practice of adding an entrainer which forms a separate phase is a specific sub-set of (industrial) azeotropic distillation methods, or combination thereof. In some senses, adding an entrainer is similar to extractive distillation.
What is the difference between azeotropic refrigerant and zeotropic refrigerant?

Which distillation separates azeotropic mixtures?
Fractional distillation is typically used to separate azeotropic mixtures by taking advantage of the differences in boiling points of the components to separate them at different stages of the column.
What does all near-azeotropic refrigerant blends exhibit?
near-azeotropic refrigerant blends all exhibit some .A )temperature glide and fractionation .B)oil problems .C) high boiling points .D)low condensing pressures

Is R-12 azeotropic?
R-12, also known as dichlorodifluoromethane, is not an azeotropic refrigerant. Azeotropes are mixtures that have a constant boiling point and composition throughout the phase change, but R-12 is a pure substance. However, it can form azeotropic-like behaviors when mixed with certain other refrigerants, but on its own, it does not exhibit azeotropic properties.
Does azeotropic mixture is miscible or immiscible?
immiscible
Refrigerants that are made up two refrigerants that when blended in the right proportions comine to make a thord stable refrigerant are called?
Refrigerants that consist of two components blended in specific proportions to create a third, stable refrigerant are known as azeotropic mixtures. These mixtures have unique properties, such as a consistent boiling point and composition during phase changes, which enhance their efficiency and effectiveness in refrigeration applications. Azeotropic blends are often used to improve performance and reduce environmental impact in cooling systems.
What are three major types of consonant blends?
The three major types of consonant blends are initial blends (blends at the beginning of a word, e.g., "bl"), final blends (blends at the end of a word, e.g., "st"), and medial blends (blends in the middle of a word, e.g., "sk").
