If the height of the mercury column in the leveling bulb is 30mm greater than that in the gas buret and atmospheric pressure is 670mm, what is the pressure on the gas trapped in the buret?
30mm
30mm
30mm !
30 mm = 3 centimetres
90 cm is greater than 9 mm
420 mm is greater than 4.2 cm
It is 30 mm/1 m = 30 mm/1000 mm = 3/100
1 meter = 100 cm = 1000 mm there are 10 mm in 1cm so 300 mm = 30 cm. greater
Cm are greater
27
3.4 cm equals 34 mm which is greater than 30 mm
