The word 'augment' means to raise by a half step musically. So, an augmented fourth would be a natural fourth ( 2 1/2 steps) raised by a half step ( a total of 3 whole steps). An augmented chord is built entirely out of augmented thirds, more commonly known as major thirds, and only contains three tones.
Generally, augmentation means to enlarge. In music theory, augmentation can be applied both to note values (time/duration) and to intervals (pitch relationship between to pitches). When you augment a note value you increase the duration of the note (the time you hold the note) over its previous value. Augmenting an interval is the process of increasing an interval by exactly one chromatic semitone (raise the interval a 1/2 step). In chord theory, an Augmented chord always means you are raising the 5th by a 1/2 step. Technically, you can augment any interval (unisons, seconds, thirds, etc.), but in practical terms, augmented intervals are reserved for the perfect intervals of 4ths and 5ths.
E flat consists of 3 flats, B flat, E flat and A flat. E flat to B flat would be a perfect 5th interval as B flat is in E flat major, but because your question was E flat to B, B is a semitone up from B flat, this would mean the interval becomes a semitone larger, and a semitone larger from a perfect interval is augmented. Therefore, the answer to your question is an augmented 5th. Hope this helps :)
Tritonic (Augmented fourth ) which is a dissonant is the most difficult to sing as melody.
Technically, any interval can be augmented by expanding it by a half-step. For instance, the augmented fourth is a perfect fourth plus a half step, etc. However, an augmented 3rd would be incredibly unusual; a composer would be much more likely to write it as a perfect fourth.
Those are both names for the same interval, where the top note is 6 half-steps (semi-tones) away from the bottom. It is also known as a tritone, and is halfway between an octave. If you start on C, the augmented fourth above is F-sharp, and the diminished fifth is G-flat. They sound the same (they are enharmonic).

An augmented second interval consists of two whole steps and one half step. In terms of scale degrees, it spans three semitones. For example, if you take C and move to D#, you cover this distance, which represents an augmented second. Thus, there are three half steps in the interval of an augmented second.
An augmented triad consists of two major thirds stacked on top of each other. In terms of half steps, the interval from the root to the major third is four half steps, and the interval from the major third to the augmented fifth is another four half steps. Therefore, an augmented triad contains a total of eight half steps from the root to the highest note.
The interval from C to A flat is a minor sixth. In terms of half steps, it spans eight half steps, which is characteristic of a minor sixth interval. This interval can also be described as an augmented fifth when considering the relationship between the notes in a different context.
An augmented third inverts to a diminished sixth.
augmented 5th, as e flat to b flat is a perfect 5th and b is a semitone above b flat, making the interval augmented
The interval between B flat (B♭) and E sharp (E♯) is an augmented fourth or diminished fifth. This is because E♯ is enharmonically equivalent to F, and the distance from B♭ to F spans four diatonic scale degrees. Thus, the interval spans six half steps, which characterizes it as an augmented fourth.
Yes
An augmented third is an interval of five semitones, spanning three note names. An example of an augmented third is C to E sharp, or C flat to E.
An augmented second is an interval comprising three semitones and two note names - for example, C to D sharp.
