Question

write the imp precautions to be taken in an experiment to determine the density of a solid by using spring balance and a measuring cylinder.

Answer 1

Heya!!
The precautions are :-

1) The liquid present in the measuring cylinder should not contain any air bubble in it.
2) The lower meniscus of the water level should be noted .
3) When the solid is immersed in the liquid , it should not touch the sides of the measuring cylinder.

Hope it helps :)

Answer 2

 

Precautions :

=>Always used a thread of least weight and volume to tie the solid block.
=>The solid block should be dried before measuring mass and volume.
=>The indicator of the spring balance should be at zero before measuring the mass of the solid.
=>The solid block should be completely immersed in water of the measuring cylinder before observing its volume.
=>While immersing the solid block, the water of the measuring cylinder should not spill.
=>The solid block should not touch the brim and sides of the beaker.
=> Lower meniscus of water level should be noted always.
