Question 1 => retort stand with
clamp;spring balance; two
beakers,500cmcube
a) containing water and labelled
water
b) containing kerosene and
labelled liquid L;set of masses
50g,100g,150g,200g,250g;threa
about 1m.
Question 2 => retort stand with
clamp;flat bottom plastic petri-
dish;syringe about
(0-10cmcube). Remove the
needle. Pull up the plunger. Use
flame from a match stick to melt
and seal the tip of the syringe to
ensure that it is air

plastic) adhesive to fix the
bottom of the petri-dish
symmetrically to the top of the
plunger; set of masses
500g,1000g,2000gand 2500g.
Note: Masses may be
improvised with fine dry sand.
