In chemistry, a pen is not used to draw lines on chromatography paper. A pencil is used to draw lines on the paper because the ink can smear and interfere with the chromatography and the ink will dissolve in the chromatography solvent.
The transparent liquid in a pen is typically ink. It is a liquid that is used to write or draw on paper when the pen tip makes contact with the surface.
Chromium was used as an alloy in ball point pens to improve the strength and durability of the pen tip.
The element used in most ball point pens is osmium, which is a rare naturally occurring element. It is usually alloyed with platinum.
Two uses for Osmium: >> With Iridium, an alloy used in making precision ball bearings & ball point pen points. >> As a catalyst in the synthesis of Ammonia (NH3) and in the hydrogenation or organic compounds.
What elements are present in ballpen
because if the ball pen used in the paper chromatography its possible that the ink of the ball pen was mixed in the food colors.
if you mess up you can erase it
because it can be rubbed out you nogging
An average ballpoint pen can typically draw a continuous line of about 1 to 2 miles before running out of ink. This can vary depending on the brand and quality of the pen.
take a pen and use dc->LineTo(point).
Ball & Roller Bearings both belongs to the category of radial contact bearings.In case of ball bearings spherical balls are used however in case of roller bearings cylindrical rollers are used.due to balls used in ball bearings there is a point contact is made whether it is line contact in roller.
get a pen or pencil, then put it on whatever your gonna draw the hose on, then do a line, then do another line parrel to it, then do a line at each end of those lines, so they are conecting, there is your hose |=========|
you don't
roller ball pens employ a mobile ball and liquid ink to produce a smoother line.
Yes, you can draw on yourself with a pen.
Mouse or light pen
You can draw a pen many different ways, be creative.
