Question

Write an activity to show that water can be made to boil even at a temperature below it's boiling point. Please answer it fast......

Answer 1

go to a place where air is not dense
this is because
if air is dense then air molecules do not have space in air i.e air is dense

but

when there is place to water molecules then it can boil even at below 100¤c

Answer 2

Steps to make water boil at temperature below its boiling point:

1. Add hot water ( around 50° C) into a syringe.

2. Close the opening of the syringe.

3. Now, pull back the plunger in horizontal position.

We may notice that the water boils.

Concept behind the activity:

Boiling point of water is 100° C at normal atmospheric condition.

When the pressure of the water is equal to the pressure of the atmosphere, then it starts to boil.

When this pressure is altered, water can even boil for few seconds at a temperature lower than 100° C.

In this activity, when plunger is pulled back, pressure gets reduced. So, water starts to boil at even 50° C.
