65. Give reasons for the following
(a) Liquids can be taken in an open container
while gas requires a closed container.
(b) Honey cannot be poured into another
container as easily as water.
c) Gases flow more than liquids.
(d) As water is subjected to heating, its tempera-
ture increases and becomes constant at 100°C
even though water is still there in the container
and the supply of heat is continued.
(e) When a solid substance is subjected to heating,
it disappears without leaving any liquid.

Answer:

Explanation:

a) Gases can go out of the container with wind as its density is so less. Wind can easily take this away. On the other hand liquids have much more density or molecules. as a result much more force needed to be applied on liquids which winds do not have.

b) Honey has more density than water. When water is poured, the gravity pull it down. So, we know, if the mass increases than more amount of force is needed to pour it. But gravity has a constant acceleration at a certain place. Thats why it takes more time to pour honey. In addition to that its sticky which resists the gravity.

c) Gases have less density.

d) At 100 c the water changes its form from liquid to gaseous. And as we know from the Heating curve that temperature and state cannot change at the same time.

e) As for this question i dont know the answer.
