Question

Salim takes 100 g of water each in four identical containers P, Q, R and S and mixes the following in them. 5 g of salt in container P 5 g of honey in container Q 5 g of coconut oil in container R 5 g of chalk powder in container S He then places all the containers in the Sun for five hours. From which container is the LEAST amount of water likely to evaporate?
a. Container P
b. Container Q
c. Container R
d. Container S

Answer 1

The container with chalk powder will contain the least amount of water, because it absorbs water, but the containers with honey and cocunut oil will conserve their amount of water, because they will prevent the water evaporation (especially cocunut oil because it will be on the top side of the container).
