Question

Give reason too and only MaTaehyung will answer this

Sunita took containers P, Q and R of equal weight and filled them with 100 mL of water from different sources, as shown below.

She placed the containers in sunlight and weighed them when they had dried up completely. Which of the containers will now weigh the MOST?

A.P

B.O

C. R

D. (All the three containers will have the same weight).

Answer 1

Answer:

The answer is P

Reason: compared to tap water and rain water salt water is more dense because if salt ions which means the presence of salt particles make it heavier compared to other two solutions

hope it helps ;)

Answer 2

$\huge\mathcal{\fcolorbox{purple}{black}{\orange{⇝Answer:-}}}$

D. (All the three containers will have the same weight).

Sunlight speeds evaporating by heating the water.

Drying is a natural process that happens due to evaporation in which the molecules at the surface of a liquid break free and escape in vapour form.

⟹ So the water of all the three containers will remain same after evaporation.
