At room temperature, ammonia (NH3) is a highly water-soluble, colorless, irritant gas with a unique pungent odor. Ammonia has a boiling point of -33Â°C and an ignition temperature of 650Â°C. Injury from ammonia most commonly is caused by inhalation, but it also may follow ingestion or direct contact with eyes or skin.
Guitar frets are thin strips of metal that are embedded in the neck of the guitar. They are raised up from the face of the fretboard in order to separate the neck into different semi-tonal intervals. This basically means that each fret indicates a different note. Frets are numbered just like the strings are. They are not, however, numbered by the metal pieces themselves but by the space in between the metal pieces. For instance, the first fret on the guitar is the space between the nut and the first metal piece. The fret wire is commonly made of a nickel/silver alloy, but stainless steel wire, although more expensive, produces longer lasting benefits.
If someone told you to place your finger on the first fret, you would go to the first fret and place your finger right behind the fret. If they told you to go to the fifth fret on the first string with your first finger, you would count up five frets and place your first finger behind that fret on the thinnest string.nowing these systems inside and out makes all of your future guitar lessons a lot faster. Weâll begin with the numbering system for the fingers on your fretting hand. Your index finger is your first finger, middle finger is your second finger, ring finger is your third finger, and your pinky is your fourth finger.
