Mercury is toxic and can be absorbed through your skin when you touch it.
To convert between absolute pressure in kPa to gauge pressure in mm Hg, you can use the conversion factor of 1 kPa = 7.5 mm Hg. Therefore, if the required absolute pressure is 20 kPa, the corresponding gauge pressure would be 20 kPa * 7.5 mm Hg/kPa = 150 mm Hg.
100 hg = hectogram
2 hg = 200 g
An objective lens should never touch the slide because it can damage both the lens and the specimen. It can also result in potential contamination and distortion of the image being viewed under the microscope. Keeping a small distance between the lens and the slide allows for proper focusing and prevents scratching or smudging.
